JAVA

中文：这个软件运行后能悬浮在所有软件之上，可以自动控制安卓系统下安装的微信，对指定微信发的每个语音进行录制后转发到指定的微信群，全程自动化，减少人工成本，当然这个软件是我很多年前（约2016年）自己开发的，现在的安卓系统和微信早就更新了不知道多少版了，所以现在应该是不能控制的，不过原理是类似的，改改应该也还可以用，这个软件在稳定性方面使用了自驱式的原理，可以说是现代人工智能的起源之一。软件原理：软件采用自驱式推进软件往前运行，通过不断截取屏幕图片，跟预置的需要识别的界面数据和需要点击的按钮图片数据进行比对（这个比对包括对图形的二值化，异化，比对等等），然后进行相关操作。多年后的今天，我发现这种自动化操作居然发展出了一个行业：RPA机器人。所以这个软件我觉得你可以看成是一个RPA机器人，这个机器人运行在安卓下对窗体应用进行自动化操作。这个软件是我很多年前自己开发的，现在把源代码公开出来，由于暂时没有时间，所以直接公开，未做代码调整和优化，希望对技术传播有所助益。本代码公开纯属技术交流，没有收取任何费用，软件分为两部分：安卓RPA机器人，控制后端，机器人使用android studio开发，后端：java+sqlserver，以webservice提供服务。 After running, this software can be suspended on all the software. It can automatically control the wechat installed under the Android system, record and forward each voice sent by the designated wechat group to the designated wechat group, and the whole process is automated to reduce labor costs. Of course, this software was developed by myself many years ago (about 2016). Now the Android system and wechat have been updated for a long time. I don't know how many versions, so it should be uncontrollable now, However, the principle is similar, and the modification should also be used. This software uses the self driving principle in terms of stability, which can be said to be one of the origins of modern artificial intelligence. Software principle: the software uses self driving to push the software forward. By constantly intercepting screen images, it compares with the preset interface data that needs to be identified and the button image data that needs to be clicked (this comparison includes binarization, alienation, comparison, etc. of graphics), and then carries out relevant operations. Today, many years later, I found that this kind of automation has developed an industry: RPA robot. So I think you can think of this software as an RPA robot, which runs under Android to automate window applications. This software was developed by myself many years ago, and now the source code is published. Because I don't have time for the time being, it is directly published without code adjustment and optimization. I hope it will be helpful to the spread of technology. This code is disclosed purely for technical exchange without any charge. The software is divided into two parts: Android RPA robot, which controls the back-end. The robot is developed using Android studio, and the back-end: java+sqlserver, which provides services with WebService.

Markov Text Generation Problem Description The Infinite Monkey Theorem1 (IFT) says that if a monkey hits keys at random on a typewriter it will almost surely, given an infinite amount of time, produce a chosen text (like the Declaration of Independence, Hamlet, or a script for ... Planet of the Apes). The probability of this actually happening is, of course, very small but the IFT claims that it is still possible. Some people have tested this hypotheis in software and, after billions and billions of simulated years, one virtual monkey was able to type out a sequence of 19 letters that can be found in Shakespeare’s The Two Gentlemen of Verona. (See the April 9, 2007 edition of The New Yorker if you’re interested; but, hypothesis testing with real monkeys2 is far more entertaining.) The IFT might lead to some interesting conversations with Rust Cohle, but the practical applications are few. It does, however, bring up the idea of automated text generation, and there the ideas and applications are not only interesting but also important. Claude Shannon essentially founded the field of information theory with the publication of his landmark paper A Mathematical Theory of Computation3 in 1948. Shannon described a method for using Markov chains to produce a reasonable imitation of a known text with sometimes startling results. For example, here is a sample of text generated from a Markov model of the script for the 1967 movie Planet of the Apes.

GALEN (defensively) Gorilla hunter stands over a dead man, one fo Besides a few spelling errors and some rather odd things that make you wonder about the author, this passage is surprisingly human-like. This is a simple example of natural language generation, a sub-area of natural language processing—a very active area of research in computer science. The particular approach we’re using in this assignment was famously implemented as the fictitious Mark V. Shaney4 and the Emacs command Disassociated Press5. Approach So, here’s the basic idea: Imagine taking a book (say, Tom Sawyer) and determining the probability with which each character occurs. You would probably find that spaces are the most common, that the character ‘e’ is fairly common, and that the character ‘q’ is rather uncommon. After completing this “level 0” analysis, you would be able to produce random Tom Sawyer text based on character probabilities. It wouldn’t have much in common with the real thing, but at least the characters would tend to occur in the proper propor- tion. In fact, here’s an example of what you might produce: Level 0 rla bsht eS ststofo hhfosdsdewno oe wee h .mr ae irii ela iad o r te u t mnyto onmalysnce, ifu en c fDwn oee iteo Now imagine doing a slightly more sophisticated level 1 analysis by determining the probability with which each character follows every other character. You would probably discover that ‘h’ follows ‘t’ more frequently than ‘x’ does, and you would probably discover that a space follows ‘.’ more frequently than ‘,’ does. You could now produce some randomly generated Tom Sawyer text by picking a character to begin with and then always choosing the next character based on the previous one and the probabilities revealed by the analysis. Here’s an example: Level 1 "Shand tucthiney m?" le ollds mind Theybooure He, he s whit Pereg lenigabo Jodind alllld ashanthe ainofevids tre lin-p asto oun theanthadomoere Now imagine doing a level k analysis by determining the probability with which each character follows every possible sequence of characters of length k (kgrams). A level 5 analysis of Tom Sawyer for example, would reveal that ‘r’ follows “Sawye” more frequently than any other character. After a level k analysis, you would be able to produce random Tom Sawyer by always choosing the next character based on the previous k characters (a kgram) and the probabilities revealed by the analysis. 4https://en.wikipedia.org/wiki/Mark_V._Shaney5https://en.wikipedia.org/wiki/Dissociated_press Page 2 of 5 At only a moderate level of analysis (say, levels 5-7), the randomly generated text begins to take on many of the characteristics of the source text. It probably won’t make complete sense, but you’ll be able to tell that it was derived from Tom Sawyer as opposed to, say, The Sound and the Fury. Here are some more examples of text that is generated from increasing levels of analysis of Tom Sawyer. (These “levels of analysis” are called order K Markov models.) K = 2 "Yess been." for gothin, Tome oso; ing, in to weliss of an’te cle - armit. Papper a comeasione, and smomenty, fropeck hinticer, sid, a was Tom, be suck tied. He sis tred a youck to themen K = 4 en themself, Mr. Welshman, but him awoke, the balmy shore. I’ll give him that he couple overy because in the slated snufflindeed structure’s kind was rath.

She’d never would be. He found her spite of anything the one was a prime feature sunset, and hit upon that of the forever. K = 8 look-a-here - I told you before, Joe. I’ve heard a pin drop. The stillness was complete, how- ever, this is awful crime, beyond the village was sufficient. He would be a good enough to get that night, Tom and Becky. K = 10 you understanding that they don’t come around in the cave should get the word "beauteous" was over-fondled, and that together" and decided that he might as we used to do - it’s nobby fun. I’ll learn you." To create an order K Markov model of a given source text, you would need to identify all kgrams in the source text and associate with each kgram all the individual characters that follow it. This association or mapping must also capture the frequency with which a given character follows a given kgram. For example, suppose that k = 2 and the sample text is: agggcagcgggcg The Markov model would have to represent all the character strings of length two (2-grams) in the source text, and associate with them the characters that follow them, and in the correct proportion. The following table shows one way of representing this information. kgram Characters that follow ag gc gg gcgc gc agg ca g cg g Once you have created an order K Markov model of a given source text, you can generate new text based on this model as follows. Page 3 of 5 1. Randomly pick k consecutive characters that appear in the sample text and use them as the initial kgram. 2. Append the kgram to the output text being generated. 3. Repeat the following steps until the output text is sufficiently long. (a) Select a character c that appears in the sample text based on the probability of that character following the current kgram. (b) Append this character to the output text. (c) Update the kgram by removing its first character and adding the character just chosen (c) as its last character. If this process encounters a situation in which there are no characters to choose from (which can happen if the only occurrence of the current kgram is at the exact end of the source), simply pick a new kgram at random and continue. As an example, suppose that k = 2 and the sample text is that from above: agggcagcgggcg Here are four different output text strings of length 10 that could have been the result of the process described above, using the first two characters (’ag’) as the initial kgram. agcggcagcg aggcaggcgg agggcaggcg agcggcggca For another example, suppose that k = 2 and the sample text is: the three pirates charted that course the other day Here is how the first three characters of new text might be generated: •A two-character sequence is chosen at random to become the initial kgram. Let’s suppose that “th” is chosen. So, kgram = th and output = th. •The first character must be chosen based on the probability that it follows the kgram (currently “th”) in the source. The source contains five occurrences of “th”. Three times it is followed by ’e’, once it is followed by ’r’, and once it is followed by ’a’. Thus, the next character must be chosen so that there is a 3/5 chance that an ’e’ will be chosen, a 1/5 chance that an ’r’ will be chosen, and a 1/5 chance that an ’a’ will be chosen. Let’s suppose that we choose an ’e’ this time. So, kgram = he and output = the. •The next character must be chosen based on the probability that it follows the kgram (currently “he”) in the source. The source contains three occurrences of “he”. Twice it is followed by a space and once it is followed by ’r’. Thus, the next character must be chosen so that there is a 2/3 chance that a space will be chosen and a 1/3 chance that an ’r’ will be chosen. Let’s suppose that we choose an ’r’ this time. So, kgram = er and output = ther. •The next character must be chosen based on the probability that it follows the kgram (currently “er”) in the source. The source contains only one occurrence of “er”, and it is followed by a space. Thus, the next character must be a space. So, kgram = r_ and output = ther_, where ’_’ represents a blank space. Page 4 of 5 Implementation Details You are provided with two Java files that you must use to develop your solution: MarkovModel.java and TextGenerator.java. The constructors of MarkovModel build the order-k model of the source text. You are required to represent the model with the provided HashMap field. The main method of TextGenerator must process the following three command line arguments (in the args array): •A non-negative integer k •A non-negative integer length. •The name of an input file source that contains more than k characters. Your program must validate the command line arguments by making sure that k and length are non- negative and that source contains at least k characters and can be opened for reading. If any of the command line arguments are invalid, your program must write an informative error message to System.out and terminate. If there are not enough command line arguments, your program must write an informative error message to System.out and terminate. With valid command line arguments, your program must use the methods of the MarkovModel class to create an order k Markov model of the sample text, select the initial kgram, and make each character selection. You must implement the MarkovModel methods according to description of the Markov modeling process in the section above. A few sample texts have been provided, but Project Gutenberg (http://www.gutenberg.org) maintains a large collection of public domain literary works that you can use as source texts for fun and practice.

My very first Java project ever made public after two years. :)

This is a Java Compiler built for my College Compiler course and for my thesis in 1997 two years after Java 1.0 was released.

The travel industry has experienced a very fast development of top-notch nature in the course of the most recent twenty years. This has basically been because of the coming of a fringeless' reality and expanded data spread about lofty situations all through the world. The expanding number of vacationers worldwide has fed the monetary and social effect extraordinarily. Be that as it may, the absence of data, correspondence, direction, arranging, and security issues has kept the travelers to skip visiting anyplace in Bangladesh and outside the nation. Along these lines, it has turned into an incredible part in Bangladesh to put with a business thought in a manner by helping voyagers by telling them about the spots, touring plans, costings, and, security. Android is the most used mobile operating system in the world right now, so design a system for android based to solve the problems faced by travelers is the best choice. Prohelika is an online travel management system application which is android based. This proposed system aimed to offer user so that they can have related information for a perfect trip, update about tour events from the group, also can have a view of cost estimation depending on the number of tourists, notification for upcoming trips. A user can have the direction to reach the destination like google play with the approximate budget to reach the place. Therefore this application is a trustworthy, secure and free of cost medium for an easy, comfortable and enjoyable travel experience. To solve the problems faced by travelers, inspire tourism by providing information, and enhancing people’s interest in traveling this android application Prohelika should create a positive outlook and gladly accepted by travelers. The project is divided into two module admin and user. We use Java, XML, Android Studio and Firebase database for the front end and back end design. After finishing the implementation, the proposed system can meet the objectives and it is obvious that the tourists and the travelers will be helped by this system.
