Java Number Pattern 10

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=5; 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:

The program defines a 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 the execution starts.
Two integer variables, i and j, are declared. These variables will be used for controlling the loop iterations.
The outer loop: for(i = 5; i >= 1; i--) - This loop iterates from i = 5 to i = 1 in reverse order (decrementing i by 1 in each iteration). This loop controls the number of rows in the pattern.
Inside the outer loop, there's a nested loop: for(j = 5; j >= i; j--) - This loop iterates from j = 5 to the current value of i in reverse order (decrementing j by 1 in each iteration). This loop controls the number of columns in each row and determines how many times the current value of i should be printed in the row.
Inside the nested loop, the statement System.out.print(i); is used to print the value of i without moving to a new line.
After the nested loop completes, System.out.println(); is used to print a newline character, moving the cursor to the next line. This effectively creates a new row in the pattern.
The nested loop and newline printing are both inside the outer loop, so the pattern repeats for each value of i, creating a triangular pattern of descending numbers.
When the outer loop completes, the entire pattern is printed.

💯 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.
