Java Number Pattern 17

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<=10; i+=2) 
  {
   for(j=i; j<=10; j+=2)
    System.out.print(j);
   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 starts by defining a class named Demo.
Inside the class, the main method is defined with the standard signature: public static void main(String[] args)
Two integer variables i and j are declared outside of the loops. These variables will be used to control the loops and print the sequence of numbers.
The outer loop: for(i=1; i<=10; i+=2) iterates through odd numbers starting from 1 up to 10. It increments i by 2 in each iteration. This loop controls the number of rows in the output.
Inside the outer loop, there's an inner loop: for(j=i; j<=10; j+=2) that iterates through odd numbers starting from the current value of i up to 10. It also increments j by 2 in each iteration. This loop controls the number of columns in each row of the output.
Within the inner loop, the statement System.out.print(j); is used to print the value of j (which is the current odd number) without a newline character. This will print the odd numbers on the same line.
After the inner loop completes, the statement System.out.println(); is used to print a newline character. This will move the printing to the next line, so the next row of odd numbers will be printed on a new line.
The inner loop will continue to execute for each value of i determined by the outer loop. Since the outer loop increments i by 2 in each iteration, the inner loop will print a sequence of odd numbers that starts from the current value of i and goes up to 10, again with increments of 2.
The entire process repeats until the outer loop finishes its iterations (i.e., until i becomes greater than 10).

💯 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.
