Java Number Pattern 5

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=1; i<=5; i++)
  {
   for(j=1; 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 declares a class named Demo.
public static void main(String[] args): This is the main method, the entry point of the program. It takes an array of strings named args as a parameter.
int i, j;: Declares two integer variables i and j which will be used as loop counters.
The outer loop: for(i=1; i<=5; i++): This loop runs from i=1 to i=5 (inclusive) and controls the number of rows in the pattern.
Inside the outer loop, we have an inner loop: for(j=1; j<=i; j++): This loop runs from j=1 to j=i (inclusive) and controls the number of columns or digits to be printed in each row. The value of i determines the number of digits to be printed in that row.
System.out.print(j);: This statement prints the value of j without a newline character, effectively printing the digits in the same line.
After the inner loop, we have System.out.println();: This statement is used to print a newline character, moving to the next line after each row is printed.
The program repeats steps 4 to 7 until the outer loop (i loop) completes all five iterations. As i increases, the number of digits printed in each row increases.

💯 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.
