, such as icontract, it is possible to put assertions into source code and convert them automatically into Java code that checks to make sure that the assertion is always valid. Because assertions processed by these tools are designated as Javadoc annotations in the original file, we can easily compile the file without having to run the preprocessor to make a "pr
One feature of the Java programming language is storage automation, which frees programmers from the error-prone process of releasing used memory. However, many programs still have to deal with resource issues, such as file and database connections, which must be explicitly released after use. As with manual management of storage, programmers make many mistakes in managing resources manually. One of these i

Like life, computers occasionally make mistakes. Once something goes wrong, you need some countermeasures. In the simplest case, you can stop the program and return an error code. This is like killing myself because I missed a plane (if I did that, even if I were a cat, my nine lives would be lost ). Although my smooth attempt brings a bit of humor, this "software suicide" option is indeed good. If the pro
