Java Number Pattern 32

Here`s a program that prints the above number pattern using Java Programming:

Demo.java

Copied

public class Demo
{
 public static void main(String[] args)
 {
  int i, j;
  for(i=1; i<=5; i++)
  {
   for(j=1; j<=i; j++)
    System.out.print((9+i+j) +" ");
   System.out.println();
  }
 }
}

💻 Testing the Program

When you run the above program, it will print the following output:

Output

11
12 13
13 14 15
14 15 16 17
15 16 17 18 19

🧠 How the Program Works

Let's break down the logic behind the code:

The program starts with the declaration of a public class named Demo.
Inside the class, there's a public static void main(String[] args) method. This is the entry point of the program where execution begins when the program is run.
Two integer variables i and j are declared to be used in the loops.
The outer for loop has a control variable i initialized to 1. The loop runs as long as i is less than or equal to 5. After each iteration, i is incremented by 1.
Inside the outer loop, there's an inner for loop with a control variable j initialized to 1. The inner loop runs as long as j is less than or equal to i. After each iteration of the inner loop, j is incremented by 1.
Inside the inner loop, the statement System.out.print((9 + i + j) + " "); is used to print the value of (9 + i + j) followed by a space. The calculated value is the sum of 9, the value of i, and the value of j. This sum is printed on the same line without moving to the next line.
After the inner loop completes, the System.out.println(); statement is used to move to the next line. This effectively starts a new line for the next iteration of the outer loop.
The outer loop continues until i becomes 6, at which point the condition i <= 5 is no longer satisfied, and the program exits the outer loop.
The result of running this program is that it generates a pattern of numbers arranged in rows and columns. Each number in the pattern is obtained by adding 9, the value of i, and the value of j.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
