Java Number Pattern 53

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, k;
  for(i=1; i<=5; i++) 
  {
   for(j=1; j<=5; j++)
   {
    if(i == j)
     System.out.print(j);
    else
     System.out.print(" ");
   }
   for(k=4; k>=1; k--)
   {
    if(i == k)
     System.out.print(k);
    else
     System.out.print(" ");
   } 
   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 Demo class is defined with a main method as the entry point of the program.
Three integer variables i, j, and k are declared to control the loops and comparisons.
The outer loop (for(i = 1; i <= 5; i++)) iterates five times, controlling the number of rows in the pattern.
Inside the outer loop, there are two inner loops that run for each value of i.
The first inner loop (for(j = 1; j <= 5; j++)) runs from 1 to 5, controlling the columns in the left half of the pattern.
Inside this loop, there's an if condition that checks if i is equal to j. If they are equal, it prints the value of j. If not, it prints a space.
The second inner loop (for(k = 4; k >= 1; k--)) runs from 4 to 1, controlling the columns in the right half of the pattern.
Inside this loop, there's another if condition that checks if i is equal to k. If they are equal, it prints the value of k. If not, it prints a space.
After both inner loops complete for a specific value of i, a System.out.println() statement is used to move to the next line, creating a new row in the pattern.

💯 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.
