Adding char as many times as a number

So I need to make a program that has the user input a height and output the following shape with nested loops:

        *
      * * *
    * * * * *
  * * * * * * *
* * * * * * * * *

My idea to get this to work is to use a char as a black space and correspond that to how many spaces I need for the right shape when given the height. However, I am having trouble calling upon it. How do I make the char, run on the same line a certain number of times. I want it to correspond with my 'x' value in the second loop.

import java.util.Scanner;
public class TrueArt 
{
public static void main(String[] args)
{
    Scanner sc = new Scanner (System.in);
    int height;
    char star = '*';


    // Gets preferred height 
    System.out.println("Enter the height you want the masterpiece to be: ");
    height = sc.nextInt();

    for (int i=0; height > i; i--)
    {
        for (int x = 0; x < height; i++)
        {
            1 + x * 2
        }
    }
}

}

Thanks for any advice in advance!

Your for loop has infinite loop issues. Try to avoid that.

By the way, another pyramid algorithm. Cheers!

for (int i=height; i > 0; i--)
{
    if(i!=1) {
        for(int y = i-1; y>0; y--) {
            System.out.print("  ");
        }
    }

    for (int x = 0; x < 2*(height-i+1)-1; x++)
    {
        System.out.print("* ");
    }
    System.out.println();

}

To have the output you want you can use this pyramid algorithm.

public static void main(String[] args) {

Scanner s = new Scanner(System.in);
int height = s.nextInt();
char star = '*';

 for(int i = 0;i < height; i++) {

    for(int j = 0; j < height - i; j++) {
        System.out.print(" ");
    }

    for(int k = 0; k <= i; k++) {
        System.out.print(star + " ");
    }
    System.out.println();  
}

}

You will have to change this a bit to get the specific shape/style pyramid you want but this is something to work off of for learning purpose.
