That makes no sense at all to me. Why not pick some less "complicated" problems and work your way up to the Good Stuff.

Just look the problem. Take it a step at a time. I assume that you can create text file that you can compile and execute with Java.


Then...

 
//Create a public class with whatever appropriate name you choose.
 
//Here's what goes in the class:
 
//Make three functions:
 
static int f1(int n)
{
    // Calculate the sum of the first n integers.
    // Maybe with a for(){} loop.
 
    // Return the square of that sum.
} // End of f1()
 
 
static int f2(int n)
{
    // Calculate the value of n times (n+1) divided by 2.
 
    // Return that value.
} // End of f2()
 
static int f3(int n)
{
    // Calculate the sum of the cubes of the first n integers.
    // Maybe with a for(){} loop.
 
    // Return that sum.
} // End of f3()
 
static void main(String [] args)
{
    // Make a for(){} loop that lets an integer variable, n, go
    // from 1 through 20.
 
    //
    // Here's the body of that loop.
    //
    BEGIN LOOP
        // Declare integer variables sum1, sum2, sum3.
        //
        // Let sum1 = f1(n), sum2 = f2(n) and sum3 = f3(n).
        //
        // Print values of n, sum1, sum2, sum3.
    END LOOP
} // End of main()

Cheers!
