On this page, we are going to learn how to check whether the character is alphabet or not using a simple Java programme.

See the given examples below:

Program 1: Check Character is alphabet or not using if-else

public class Alphabet { public static void main(String[] args) { isAlphabetCharacter('S'); isAlphabetCharacter('@'); isAlphabetCharacter('7'); isAlphabetCharacter('j'); } // Method to check whether the character is alphabet or not static void isAlphabetCharacter(char ch) { if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) System.out.println(ch + " is an alphabet character"); else System.out.println(ch + " is not an alphabet character"); } }

Output

S is an alphabet character
@ is not an alphabet character
7 is not an alphabet character
j is an alphabet character

Program 2: Check whether alphabet or not using Scanner class

import java.util.Scanner; public class Alphabet2 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter the character: "); char ch = scanner.next().charAt(0); scanner.close(); // Checking whether the input character is alphabet or not if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) System.out.println(ch + " is an alphabet character"); else System.out.println(ch + " is not an alphabet character"); } }

Output 1 :

Enter the character: S
S is an alphabet character

Output 2 :

Enter the character: 7
7 is not an alphabet character

Output 3 :

Enter the character: #
# is not an alphabet character
