Java doesn't allow methods in methods. You need a class and inside that class you arange your methods like

someClass {

    methodA {
    } //end of methodA

    methodB {
    } //end of methodB

} //end someClass

main is defined as the start point of your program. When the program is executed the JVM is looking for the main method and running the code here. That's all. If you want to structure your program or want to avoid repetitions you write other methods and/ or classes. But per definition methods are't allowed to be in other methods.
