Java Number Pattern 49

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++) 
  {
   for(j=1; j<=i; j++)
    System.out.print(j*i +" ");
   System.out.println();
  }
 }
}

💻 Testing the Program

When you run the above program, it will print the following output:

Output

1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36
7 14 21 28 35 42 49
8 16 24 32 40 48 56 64
9 18 27 36 45 54 63 72 81
10 20 30 40 50 60 70 80 90 100

🧠 How the Program Works

Let's break down the logic behind the code:

public class Demo: This defines a class named Demo.
public static void main(String[] args): This is the main method where the program's execution begins. It takes an array of strings (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 <= 10; i++): This loop iterates from i = 1 to i = 10, incrementing i by 1 in each iteration.
Inside the outer loop, there's an inner loop: for(j = 1; j <= i; j++): This loop iterates from j = 1 to j = i in each iteration of the outer loop, incrementing j by 1.
Inside the inner loop, the program prints the product of i and j followed by a space: System.out.print(j * i + " ");. This is what generates the multiplication table values.
After the inner loop completes, the program adds a new line using System.out.println();. This moves the cursor to the next line, creating the structure of a table.
The outer loop repeats these steps for each value of i from 1 to 10, generating the multiplication table 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.
