Printing out two variables on one line?

I can't seem to figure out how to print both variables i and balance. When i use + it actually adds them. I also tried several other ways to do it that I looked up on Google but they didn't come out correct either. However When I print out either variable i or balance by themselves, I do get the correct result. Can someone help me?

import java.util.*; 

public class Forloops
{
    public static void main (String [ ] args)
    {
        System.out.print("Enter Balance:");
        double balance = input.nextDouble();

        System.out.print("Enter Number of Months:");
        int i = input.nextInt();

        for ( i = 0; i <= 12; i = i + 1 ) 
        {
            balance = balance * (1.00417);
            System.out.println( balance);
        }
    }
}

When you have a string and sum it with an integer, Java will cast the integer to string automatically. The problem is that you aren't using any string inside the println() function. So the basic thing is to add "" between i and balance.

System.out.println(i + "" + balance);

This would work fine, but you have to know why. If balance was a string, using the way you thought would work, don't forget this, java will cast the variable when needed, when you should've done, like adding two different type of variables.

Alternatively

System.out.println(i + "" + balance);

or 

System.out.println("After " + i +" months: " + balance);

Try

System.out.println("I = " + i + " balance = " + balance);

try 

System.out.println(String.valueOf(i) + String.valueOf(balance))
