HOW TO PRINT TIANGLE PATTERN IN JAVA PROGRAM||JAVA PROGRAM || Singhania coder...

To print a triangle pattern in Java, you can use nested loops to handle the spaces and the stars for each row. Below is a simple example of how to print a right-angled triangle pattern using stars (*).

Example: Printing a Right-Angled Triangle Pattern

Here is a Java program to print a right-angled triangle pattern with stars:

`public class TrianglePattern {`

`public static void main(String[] args) {`

`int rows = 5; // Number of rows in the triangle pattern`

`// Outer loop to handle the number of rows`

`for (int i = 1; i <= rows; i++) {`

`// Inner loop to print the stars`

`for (int j = 1; j <= i; j++) {`

`System.out.print("* "); // Print star followed by space}System.out.println(); // Move to the next line after each row}}}`Output:
` * ** * * ** * * * *`

Explanation:
The outer loop (`for (int i = 1; i <= rows; i++)`) runs for each row.

The inner loop (for (int j = 1; j <= i; j++)) runs and prints stars depending on the row number. For the first row, one star is printed, for the second row, two stars are printed, and so on.
After each row, the println() method is used to move to the next line.

Example: Printing an Inverted Triangle Pattern

Here is an example where the triangle is printed upside down:

public class InvertedTrianglePattern {
    public static void main(String[] args) {
        int rows = 5;  // Number of rows

        // Outer loop to handle the number of rows
        for (int i = rows; i >= 1; i--) {
            // Inner loop to print stars
            for (int j = 1; j <= i; j++) {
                System.out.print("* ");  // Print star followed by space
            }
            System.out.println();  // Move to the next line after each row
        }
    }
}

Output:

* * * * * 
* * * * 
* * * 
* *

In this program, the outer loop runs in reverse, starting from rows and going down to 1. This creates the effect of an inverted triangle.

Conclusion:

The key to creating triangle patterns in Java is using loops: an outer loop to control the rows and an inner loop to print stars or spaces for each row. You can modify the pattern as needed by changing the number of rows or the content being printed.
