Java Program to Print Left Triangle Star Pattern

import java.util.Scanner;

public class Main
{
  public static void main(String args[])
  {
    int k = 5, num;
    int i, j;

    Scanner sc = new Scanner(System.in);

    System.out.print("Enter the number of rows: ");
    num = sc.nextInt();

    for (i = 0; i < num; i++)
    {
      for (j = 2 *(num - i); j >= 0; j--)
        System.out.print(" ");

      for (j = 0; j <= i; j++)
        System.out.print("* ");

      System.out.println();
    }
  }
}
