Java Program: Java Program to Display the Pattern

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

Java Program: Java Program to Display the Pattern

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

✅ Explanation

🔹 Outer Loop (i)

• Controls the number of rows (5 → 1).
• Each row prints fewer letters than the previous one.

🔹 Inner Loop (j)

• Prints alphabets starting from A.
• Number of characters printed equals the row number.

🔹 Character Increment

ch++;

• Moves to the next alphabet.

🔹 Line Break

System.out.println();

• Moves to the next line after each row.

✅ Key Concepts Used

✔ Nested loops
✔ Character variables
✔ Pattern logic
