Java Number Pattern 25

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=i; j<=5; j++)
   {
    if(i < 4)
     System.out.print(i);
    else
     System.out.print(6 - 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:

The program begins with the declaration of a public class named Demo.
Inside the class, the main method is declared with the standard signature: public static void main(String[] args).
Within the main method, two integer variables i and j are declared. These variables are used for loop control.
The outer loop, for(i=1; i<=5; i++), iterates over the values of i from 1 to 5 (inclusive). This loop controls the number of rows printed in the output.
Inside the outer loop, there is an inner loop, for(j=i; j<=5; j++), which iterates over the values of j starting from the current value of i to 5 (inclusive). This loop controls the number of columns printed in each row.
Inside the inner loop, there's an if-else condition:
- If i is less than 4, the program prints the value of i using System.out.print(i).
- Otherwise (when i is 4 or 5), the program prints the value 6 - i. This is done to print 3 when i is 4, and 2 when i is 5.
After the inner loop completes, the program executes System.out.println(); to move to the next line, creating a new row in the output.
The outer loop repeats this process for each value of i from 1 to 5.
Once all iterations are complete, the program exits the main method.

💯 Tips for Enhancement:
