In this article, we will learn to print the different Number pattern programs in Java. This is one of the important Java interview questions for fresher. Let’s look into the below possible number pattern programs
Number 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 to print the pattern ");
int rows = scanner.nextInt();
System.out.println("** Printing the pattern... **");
for (int i = 1; i <= rows; i++)
{
for (int j = 1; j <= i; j++)
{
System.out.print(j + " ");
}
System.out.println();
}
}
}
Output
Enter the number of rows to print the pattern 5 ** Printing the pattern... ** 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5
Pattern 2:
package com.javainterviewpoint;

int rows = scanner.nextInt();
System.out.println("** Printing the pattern... **");
for (int i = 1; i <= rows; i++)
{
for (int j = 1; j <= i; j++)
{
System.out.print(i + " ");
}
System.out.println();

Explaining little more. first array digit is 6 so java program should print 6 asterisk then 2, 3 like this. And if its 9 then print nine starts. This should be bottom to top approach
javainterviewpoint says
Can you brief me a little more on this, let me put my understanding first value is 6 so it should print 6 asterik from bottom to top, now what to 2,3 does there how it adds up space there? what is the logic behind it? also, post the pattern once again wrapped in <pre></pre> tag.
Sachin batra says
Yes asterik would print according to arrays value. first value is 6 it should print 6 asterik and so on…
