im creating a program which requires me to pass 2 variables to an another method in the same class. However, i have no idea how to do it as its my 1st time working with multiple methods. So i have one method that collects 2 double variables from the user in the main method, then i need to transfer those two variables to another method that does some calculations. how would i transfer those 2 variables?

In what way are the first method and the second method different?

Why can't you pass the arguments from (first) to (second) the same way you pass from (main) to (first)?

i dont quite understand what u mean by the same way as first and second. Im required to do an assignment that asks to create 2 methods, one that does the calculation and the other gets the input. however, there are 2 input variables and i dont know how to transfer the variables from one method to another.

Here's an example for one argument, of type int. You should be able to extrapolate...

Java:

public class Example {
    public static void main ( String[] args ) {
        System.out.println ( methodOne(5) );
    }

    private static int methodOne ( int x ) {
        return x * x;
    }
}

Replace the 5 in the main method with your variable. If you have multiple variables, make the method accept multiple parameters.

If you aren't sure how to do that, this site summaries it.
