when we are creating a new class, and we want to make use of a lot of methods, we do something like this? (we put all the methods inside the main method? or only the void methods?)

Code:

public main method (){
method2();
method3();
}

public void method2(){
blah blah blah}

public method3 (){
blah blah blah
return value;
}

how can we use in a (return) method a variable that is included in a previous (void) method?

Code:

public class MethodsTest {
    public static void main(String[] args) {
        doSomething();
        String s = getSomething();
        String retVal = doSomethingElse(s);
        System.out.println("retVal = " + retVal);
    }

    private static void doSomething() {
        System.out.println("doingSomething");
    }

    private static String getSomething() {
        return "something";
    }

    private static String doSomethingElse(String s) {
        return "somethingElse " + s;
    }
}

you are fast thanx


if i wanted to return the ''somethingElse '' to the method getSomething, i would write this

Code:

 String retVal = doSomethingElse(s);
        System.out.println("retVal = " + retVal);

as it is inside the getSomething method (and no reference of it in the main method)?

A method can call other methods.

Code:

public static void main(String[] args) {
        String s = getSomething();
        System.out.println("s = " + s);
    }

    private static String getSomething() {
        String s = getSomethingElse();
        return "something + " + s;
    }

    private static String getSomethingElse() {
        return "somethingElse";
    }
