Java Number Pattern 9

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(i);
   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 program starts by defining a class named Demo.
Inside the class, there's a public static void main(String[] args) method, which is the entry point of the program.
Inside the main method, two integer variables are declared: i and j. These variables will be used as loop counters.
The outer loop (for(i = 1; i <= 5; i++)) runs from i = 1 to i = 5. This loop controls the number of rows in the triangle.
Inside the outer loop, there's an inner loop (for(j = 1; j <= i; j++)). This loop runs from j = 1 to j = i on each iteration of the outer loop. It controls the number of columns (or characters) in each row of the triangle.
Inside the inner loop, System.out.print(i) is used to print the value of i. Since the inner loop iterates from j = 1 to j = i, this means that the value of i will be printed i times in each row.
After the inner loop, System.out.println() is used to move to the next line, creating a new row for the triangle pattern.
The outer loop repeats these steps for each value of i, resulting in the complete pattern being printed.

💯 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.
