Java Program: Java Program to Display the Pattern

2 (vii). Write a program in Java to display the following patterns.

Java Program: Java Program to Display the Pattern

public class ReverseNumberPattern {
    public static void main(String[] args) {
 
        for (int i = 5; i >= 1; i--) {
 
            for (int j = i; j >= 1; j--) {
                System.out.print(j + " ");
            }
 
            System.out.println();
        }
    }
}

✅ Explanation

🔹 Outer Loop (i)

• Controls the number of rows (5 → 1).

🔹 Inner Loop (j)

• Prints numbers in reverse order from i down to 1.

🔹 Line Break

System.out.println();

• Moves to the next line after each row.

✅ Key Concepts Used

✔ Nested loops
✔ Reverse counting
✔ Pattern formatting
