Question

Hi everyone! I need help on my Java assignment.

I need to create a method that is called sumIt that will sum two values and will return the value.It should also invoke cubeIt from the sum of the two values. I need to change the currecnt program that I have to make it input two values from the console. The method has to be called sumIt and will return to the sum that will produce the cube of the sum by calling the cubeIt method. I hope this is all making sense as I am confused myself. Thanks for any help!

This is the code that I have so far.:

package journal4c;

import java.util.Scanner;
import java.text.NumberFormat;

public class Journal4C
{
Scanner in = new Scanner(System.in);
  
public int getValue()
{
System.out.println("Enter a number ");
int val;
val = in.nextInt();
return val;
}
public int cubeIt(int num)
{
return num*num*num;
}
  
public static void main(String[] args)
{
Journal4C c = new Journal4C();
int x = c.getValue();
System.out.println("The value you entered is " + x);
int cube = c.cubeIt(x);
System.out.println("The cube of your value is " + cube);
  
  
}
}

java code:

package journal4c;
import java.util.Scanner;
import java.text.NumberFormat;

public class Journal4C {
  
Scanner in = new Scanner(System.in);
  
public int sumIt()
{
  
  
System.out.println("Enter two number ");
int a,b;
// reading two numbers
a = in.nextInt();
b=in.nextInt();
int sum =a+b; // get sum

// invoke the cubeIt method
cubeIt(sum);

return sum; // returning sum

}

// method to find cube
public void cubeIt(int num)
{
int cube=num*num*num;
System.out.println("The cube of sum is " + cube);
}
  

// main method
public static void main(String[] args)
{
Journal4C c = new Journal4C();

System.out.println("The sum is " + c.sumIt());

}
          

}
