Given Input: 

  char ch = '2'; // Change this to test different characters

Expected Output: 

2 is a digit.

Program:

public class Main {
    public static void main(String[] args) {
        char ch = '2'; // Change this to test different characters

        if (Character.isLetter(ch)) {
            System.out.println(ch + " is a letter.");
        } else if (Character.isDigit(ch)) {
            System.out.println(ch + " is a digit.");
        } else {
            System.out.println(ch + " is a special symbol.");
        }
    }
}

Output:

2 is a digit.

Explanation:

This code uses the Character.isLetter(char ch) method to check if the character is a letter, the Character.isDigit(char ch) method to check if the character is a digit, and the else clause to handle special symbols.

Here are some examples of how the output will look:

  • If ch is 'a', the output will be: a is a letter.
  • If ch is '5', the output will be: 5 is a digit.
  • If ch is '@', the output will be: @ is a special symbol.

You can test different characters by changing the value of ch in the code.
