Calculating Squares and Cubes in a table

[aldorfski_17]

Hey All,

I'm sorry if I sound rushed, but I need some help with one of my assignments. I am having some issues coding my "for" loops. I have an assignment that requests a table that receives an integer input. Once I input an integer, the table will display all of the squared and cubed numbers of every number leading up to that input. See example below:

enter integer: 3

Number Square Cube
1 1 1
2 4 8
3 9 27

continue? (y/n):

The code I have just keeps repeating and does not increment. I tried incrementing up to the input, but that didn't work either. Any help is greatly appreciated. Thanks.

See code below:

import java.util.Scanner;

public class PowerTableDisplayer {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		// Code to display "Welcome to the Squares and Cubes Table
		System.out.println("Welcome to the Squares and Cubes Table");
		System.out.println();
		
		// Create a Scanner object
		Scanner sc = new Scanner(System.in);
		
		
		
		String choice = "y";
		while(choice.equalsIgnoreCase("y"))
		{
		    	// get the input from the user
				System.out.println("Enter an Integer: ");
                int integerNext = sc.nextInt();     
                
               
                System.out.println("Number" + "  " + "Squared" + "  " + "Cubed");      	
        		System.out.println("======" + "  " + "======" + "  " + "======");
        		
       
        for (int i = 1; i > 0; i++)
        {      
        i = integerNext;
        int numberSquared = (int) Math.pow(i, 2);
        int numberCubed = (int) Math.pow (i, 3);
        
        
        String message = "\n" + i + "       " + numberSquared + "       " + numberCubed;
        
        System.out.println(message);
        System.out.println();
        
        // see if the user wants to continue
        System.out.print("Continue? (y/n): ");
        choice = sc.next();
        System.out.println();
        
        }
        
        
        
        }
		
        
        
		}
			   
        			}

Well, when you start your for loop, you set the value of i to integerNext, so every iteration works with the same value. I think a much better way would be like this:

for(int i = 1; i <= integerNext; i++) {
//the rest of the code goes here
}

And learn to use code tags and proper indentation, readability is important, especially if you want others to read your code.

Hey MoonChile,

Thanks for your reply. After implementing the change, the program ends after the first line.

Enter integer: 3

Number Squared Cubed
3 9 27

Any thoughts on how I can get the Number 1 and 2 to show up, as well as the Square and Cubed numbers for each?

Remove this line from the body of your loop:

i = integerNext;

kind regards,
