Java Number Pattern 52

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, m;
  for(i=1; i<=5; i++)
  {
   m = i;
   for(j=1; j<=i; j++)
    System.out.print(m++);
   m = m - 2;
   for(k=1; k<i; k++)
    System.out.print(m--);
   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:

The program defines a class named Demo.
Inside the class, there's a main method, which is the entry point of the program.
Four integer variables are declared: i, j, k, and m.
The outer loop (for(i=1; i<=5; i++)) runs from i = 1 to i = 5, controlling the number of rows in the output pattern.
Inside the outer loop, m is initialized with the value of i. This value of m will be used to print increasing and decreasing numbers.
The first inner loop (for(j=1; j<=i; j++)) runs from j = 1 to j = i, responsible for printing the increasing sequence of numbers. The value of m is printed and then incremented.
After the first inner loop, m is decremented by 2 (m = m - 2).
The second inner loop (for(k=1; k<i; k++)) runs from k = 1 to k = i - 1, responsible for printing the decreasing sequence of numbers. The value of m is printed and then decremented.
After both inner loops, a newline character is printed using System.out.println() to move to the next line for the next row of the pattern.
Steps 4 to 9 are repeated for each value of i from 1 to 5, resulting in the desired pattern of increasing and decreasing numbers in rows.
The program execution completes when the outer loop finishes running.

💯 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.
