Java Number Pattern 59

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;
  int k = 6, l = 13, m = 16;
  for(i=1; i<=5; i++)
  {
   for(j=1; j<=5; j++)
   {
    if(i == 1)
     System.out.format("%-3d", j);
    else if(j == 5)
     System.out.format("%-3d", k++);
    else if(i == 5)
     System.out.format("%-3d", l--);
    else if(j == 1)
     System.out.format("%-3d", m--);
    else
     System.out.print("   ");
   }
   System.out.println();
  }
 }
}

💻 Testing the Program

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

Output

1  2  3  4  5
16          6
15          7
14          8
13 12 11 10 9

🧠 How the Program Works

Let's break down the logic behind the code:

The program defines a class named Demo.
The main method is the entry point of the program, which takes an array of strings as its argument.
Three integer variables k, l, and m are initialized to 6, 13, and 16 respectively.
The outer loop (for loop) runs from i = 1 to i <= 5 for each row.
Inside the outer loop, an inner loop (for loop) runs from j = 1 to j <= 5 for each column within the current row.
The following conditions are checked for each position (i, j) in the grid:
- If i == 1, it means the first row, so the column number j is printed left-aligned with a width of 3.
- If j == 5, it means the last column, so the value of k is printed left-aligned with a width of 3, and then k is incremented.
- If i == 5, it means the last row, so the value of l is printed left-aligned with a width of 3, and then l is decremented.
- If j == 1, it means the first column (excluding the first row), so the value of m is printed left-aligned with a width of 3, and then m is decremented.
- If none of the above conditions are met, three spaces are printed to create a visual gap in the grid.
After printing all columns in a row, a newline character is printed to move to the next row.
The loops continue until all rows and columns are processed.

💯 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.
