Problem:
Write a program that prompts the user to enter an intger from 1 to 15 and displays a pyramid, as shown in the following sample run:

Enter the number of lines: 7
______1
_____212
____32123
___4321234
__543212345
_65432123456
7654321234567

those are suppose to be spaces instead of underscores...its only way i could make it look right on this post

i have got the right side of it, but i'm stuck on how to get the left side.

import java.util.Scanner;
public class pyramid {
	public static void main(String[] args) {
	Scanner input = new Scanner(System.in);
 
	System.out.print("enter lines: ");
	int k = input.nextInt();
 
	for (int i=1; i<=k; i++){
		for (int j=1; j<=i; j++){
			System.out.print(" " +j);}
			System.out.print("\n");
	}
	}
}

....
I omitted the scanner part.
