Java Number Pattern 14

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=7; i>=1; i-=2)
  {
   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 declares the 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 args as its argument, although it's not used in this program.
int i, j;: Declares two integer variables i and j which will be used for loop control.
for(i=7; i>=1; i-=2) {: This is an outer loop that starts with i equal to 7 and decrements it by 2 in each iteration until it becomes less than 1. The loop controls the number of rows in the pattern.
for(j=1; j<=i; j++) {: This is an inner loop that starts with j equal to 1 and increments it by 1 in each iteration until it becomes equal to the value of i. The loop controls the number of columns and the values printed in each row.
System.out.print(j);: This prints the value of j (which starts at 1 and increments in each iteration) without moving to the next line.
System.out.println();: This prints a newline character, moving to the next line after each row of numbers is printed.
The inner loop continues until j becomes equal to i, printing a sequence of numbers on the same line.
After the inner loop completes, System.out.println(); is called, moving to the next line to start printing the next row of numbers.
The outer loop continues until i becomes less than 1. This controls the number of rows in the pattern.

💯 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.
