    Question How do you convert a jar file into a java file, how ?

    how do you convert a jar file into a java file ?

    I am new to Java ,but have a little experience in C++ and Visual Basic.

    I want to edit and maybe create my own mobile games that are written or converted into jar files.

    At the moment I am using Java NetBeans , and Easy Java( the java pad).

    However the only solution I tried was to open the JAR file in winrar and see that its made up of png picture files,
    midi music files and class files. Unfortunately when I uncompressed the JAR file , there was NO java file to be seen and the JAVA editors Do not show the class file like a Java file. So why is there no extension Java file in the mobile JAR game ?

    I'm not quite sure I understand you...

    Jar files are basically Java zip files, which can contain embedded run commands for running a Java application.

    Java files are the source files which can be edited using any text editor. These are in turn compiled down to .class files which contain the bytecode to be run by the JVM. You can "disassemble" these .class files, but it's very likely you won't get back anything that's terribly useful and it will probably require considerable knowledge to reverse engineer the source.

    Reverse engineering a downloaded jar is almost always disallowed by license. Also, the simple fact that you expected to find source files in a jar archive suggest that you need to go through much more fundamental tutorials before taking up game programming.

    Here's a good starting point: The Java™ Tutorials
