How to draw a ChristmasTree

Question:

Using Java, write a code that creates a Christmas Tree. The code will ask user to enter a number that means the height of the tree.

Code:

import java.util.Scanner;
 
public class ChristmasTree {
 
   public static void main(String args[]) {
 
      Scanner sc = new Scanner(System.in);
 
      System.out.print("Enter height: ");
      int height = sc.nextInt();
 
      for (int i = 0; i < height; ++i) {
  for (int j = -height + 1; j < -i; ++j) {
     System.out.print(" ");
  }
  for (int j = -i; j <= i; ++j) {
     if (j == 0) {
        System.out.print("|");
     } else if (j < 0) {
        System.out.print("\\");
     } else {
        System.out.print("/");
     }
  }
  System.out.println("");
      }
   }
}

Output:
