Question

PLEASE READ THE FULL INSTRUCTION.

Write a Java programme to print the pattern of asterisks shown below. For i=1 For i=2 * * For i=3 For i=n ** * ** ** ......... * (n asterisks) Your program should prompt the user to enter the value of n and then draw the corresponding star pattern. Remember if n is 5, you will have to print five patterns for i=1, i=2, i=3, i=4, and i=5. If n is 3, you will have to print three patterns for i=1, i=2, and i=3. Name your java file as Lab6_Task.java.

Answer 1

import java.util.Scanner;
public class Lab6_Task2 {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter value for n: ");
        int n = scan.nextInt();
        for(int i = 1;i<=n;i++){
            System.out.println("For i="+i);
            for(int k = 0;k<i;k++) {
                for (int j = 0; j <= k; j++) {
                    System.out.print("* ");
                }
                System.out.println();
            }
        }
    }
}

Output

Enter value for n: 5 For i-1 For i=2 For i=3 For i 4 For i-5
