Java Number Pattern 4

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=5; 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:

Output

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This line defines a Java class named Demo.
public static void main(String[] args): This line defines the main method, which serves as the entry point for the program. It takes an array of strings (args) as its parameter.
int i, j;: Declares two integer variables i and j.
for(i=1; i<=5; i++): This is an outer loop that iterates from i = 1 to i = 5. The loop control variable i is incremented by 1 in each iteration.
Inside the outer loop, there is another loop:
- for(j=5; j>=i; j--): This is an inner loop that iterates from j = 5 down to j = i. The loop control variable j is decremented by 1 in each iteration.
- System.out.print(j);: Prints the value of j (which is the loop control variable of the inner loop) without a newline character.
System.out.println();: This prints a newline character to move to the next line after the inner loop completes.

💯 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.
