Java Program: Java Program to Display the Pattern

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

Java Program: Java Program to Display the Pattern

public class JavaWordPattern {
    public static void main(String[] args) {
 
        char[] word = {'I', 'C', 'S', 'E'};
 
        for (int i = 0; i < word.length; i++) {
 
            for (int j = 0; j <= i; j++) {
                System.out.print(word[j] + " ");
            }
 
            System.out.println();
        }
    }
}

I
I C
I C S
I C S E

✅ Explanation

🔹 Character Array

char[] word = {'I', 'C', 'S', 'E'};

• Stores the letters of the word ICSE.

🔹 Outer Loop

• Controls the number of rows.
• Each row prints one additional character.

🔹 Inner Loop

• Prints characters from index 0 to i.

🔹 Line Break

System.out.println();

• Moves to the next line after each row.

✅ Key Concepts Used

✔ Character arrays
✔ Nested loops
✔ Pattern logic
