Java Number Pattern 11

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=5; i>=1; i--) 
  {
   for(j=1; j<=i; j++)
    System.out.print(i);
   System.out.println();
  }
 }
}

💻 Testing the Program

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

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This declares a Java class named Demo.
public static void main(String[] args): This is the main method of the program where the execution begins when the program is run. It takes an array of strings args as input, although in this program, args is not used.
int i, j;: Two integer variables i and j are declared without being initialized. These variables will be used as loop counters.
for(i=5; i>=1; i--): This is an outer loop that starts with i initialized to 5 and iterates as long as i is greater than or equal to 1. In each iteration, i is decremented by 1.
for(j=1; j<=i; j++): This is an inner loop nested within the outer loop. It starts with j initialized to 1 and continues as long as j is less than or equal to the current value of i. In each iteration of this loop, the value of i is printed using System.out.print(i).
System.out.print(i);: Inside the inner loop, this line prints the value of i without moving to a new line.
System.out.println();: After the inner loop completes, this line prints a newline character to move to the next line.
After the completion of the inner loop, the outer loop iterates again with a decreased value of i, repeating the process until i becomes 0.

💯 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.
