Once we declare a variable’s data type, it can only hold that type of data throughout the execution of the program. For example, imagine we have a file of Java code that was written and compiled to bytecode on a computer running the Windows operating system. This bytecode can be executed (that is, the program can be run) by a JVM on any platform, including Windows, Mac OS, Linux, and so on. The benefit of this setup is that it allows bytecode compiled on particular operating systems and platforms to be executed by a JVM on any other platform.
- If you browse into it, you’ll see all of the files and subfolders that make up the project you downloaded.
