In this article, we will learn to print the different Star Pattern Programs in Java. This is one of the popular Java pattern program interview question for fresher. The pattern program are the most recommended programs to enhance the logical thinking and for the better understanding of flow control. Lets look into the below possible Star Pattern Programs in Java which might help for both the fr
Star Pattern Programs In Java
Pattern 1:
package com.javainterviewpoint;
import java.util.Scanner;
public class Pattern1
{
public static void main(String[] args)
{
// Create a new Scanner object
Scanner scanner = new Scanner(System.in);
// Get the number of rows from the user
System.out.println("Enter the number of rows needed to print the pattern ");
int rows = scanner.nextInt();
System.out.println("## Printing the pattern ##");
// Print i number of stars
for (int i=1; i<=rows; i++)
{
for (int j=1; j<=i; j++)
{
System.out.print("*");
}
System.out.println();
}
scanner.close();

}
Output
Enter the number of rows needed to print the pattern 5 ## Printing the pattern ## * ** *** **** *****
