Java Number Pattern 6

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=i; j<=5; j++)
    System.out.print(j);
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This declares a new class named Demo.
public static void main(String[] args): This is the entry point of the program. The main method is where the program execution begins. It takes an array of strings args as input, which can be used to pass command-line arguments to the program.
int i, j;: Declares two integer variables i and j which will be used in the loops.
for(i=5; i>=1; i--): This is an outer loop that iterates from i=5 down to i=1 in decreasing order. This loop controls the number of rows in the output pattern.
Inside the outer loop, there is an inner loop: for(j=i; j<=5; j++). This inner loop starts with the value of j being equal to the current value of i and iterates up to j=5. This loop controls the numbers printed in each row.
System.out.print(j);: This line prints the value of j (which ranges from the current value of i to 5) without a newline character, effectively printing the numbers in the same row.
System.out.println();: After the inner loop finishes, this line is executed to print a newline character, which moves the cursor to the next line. This creates the effect of starting a new row for the next iteration of the outer loop.
After both loops complete, the program exits the main method and terminates.

💯 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.
