Java Number Pattern 8

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(j);
   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 line defines the beginning of a Java class named Demo.
public static void main(String[] args): This is the main method of the program, which is the entry point for execution. It takes an array of strings args as input (command line arguments).
int i, j;: Two integer variables, i and j, are declared to be used as loop counters.
for(i=5; i>=1; i--): This is an outer loop that starts with i having a value of 5 and iterates as long as i is greater than or equal to 1, decrementing i by 1 in each iteration.
for(j=5; j>=i; j--): Inside the outer loop, there is an inner loop. The inner loop initializes j to 5 and iterates as long as j is greater than or equal to the current value of i. In each iteration, j is decremented by 1.
System.out.print(j);: Within the inner loop, this line prints the current value of j (which is decreasing due to the loop) without moving to the next line.
System.out.println();: After the inner loop completes, this line is executed to print a newline character, moving to the next line.
After the completion of the inner loop and the newline is printed, the outer loop iterates to the next iteration, and the process continues.

💯 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.
