Well off with you to learn JAVA -------- array introduction, java -------- Array Today, I will share with you an important data type in JAVA learning-array. To store a series of related data, using arrays is a good choice. In addition, if a program fragment often appears repeatedly, defining it as a method can effectiv
Introduction to CC language structure is extremely compact, C language is a modular programming language, the entire program can be divided into several relatively independent function modules, mutual calls between modules and data transfer is very convenientC language is very powerful in its expressive ability. The C language takes into account the features of high-level languages and assembly language, as

usage. Finally, if your test set--the set of test instances--is very thorough, and when all the tests are passed, you can say that your code is complete. Interestingly, this view also happens to be one of the features of test driven Development (testing-driven development). Test driven Development (TDD) is also considered the test first coding (pre-coded test). Test first coding is a way to take tests one step further: Write a test before you write any code.

During the Spring Festival read the next "java:the complete Reference" found this writing in simple, I think a question, the book a lot of content we also know, but why we can not write such a book, so comprehensive, so systematic, so simple and easy to understand. Have to admire Herbert Schildt programming skills, need to mention is Herbert Schildt wrote a lot of Java and C, C + + books, he is the C, C + +
easier to maintain. Java code redundancy is also well known, and most attacks to the Java language will directly target Java's tedious and rigid syntax (but I think this is also one of the advantages of Java, as mentioned in the first section of this book, "conservative design ideas are the biggest advantage of Java".
variable configuration methodAfter we have configured the successful PATH environment variable and found that Java and Javac can run everywhere, then we have no need to put the source code in the bin directory, but we have encountered a problem is that the source file referenced in the tool class could not find what to do at this time? In fact, this is because Java is an object-oriented
