    jar file maybe an executable file, or a collection of libraries
    1.executable
    .jar file consists of resources(such as images,input files) and the .java file (main class and other clases) and the compiled file(.class file), with the compiled main class file(.class format) as a header (the header consists of the main class' compile file)
    2.a list of libraries (packages) could be in a jar file, whose methods and fields can be imported into our class
