Java Character isAlphabetic() Method

Java isAlphabetic() method is a part of Character class. This method is used to check whether the specified character is an alphabet or not.

A character is considered to be an alphabet if provided by getType(codePoint) has the following characteristics:

  • Other alphabets defined by the Unicode Standard.


public static boolean isAlphabetic(int codePoint)  


The parameter passed is the Unicode codePoint Character which is to be checked whether it is an alphabet or not.


Returns boolean value true if the specified character is an alphabet else return false.

Example 1:

Here, the isAlphabetic() method checks the specified character whether it is an alphabet or not.

public class StudyTonight 
	public static void main(String[] args) 
		int cp1 = 56;
		int cp2 = 88;

		boolean b1 = Character.isAlphabetic(cp1);
		boolean b2 = Character.isAlphabetic(cp2);

		System.out.println((char) cp1 + " is alphabet? " + b1);
		System.out.println((char) cp2 + " is alphabet? " + b2);


8 is alphabet? false
X is alphabet? true

Example 2:

Here is a user-defined example where anyone using this code can put a value of his choice and get the output.

import java.util.Scanner;
public class StudyTonight 
	public static void main(String[] args) 
			System.out.print("Enter Unicode codepoint input: ");
			Scanner sc = new Scanner(System. in );
			int cp = sc.nextInt();
			boolean b = Character.isAlphabetic(cp);

			if (b == true) 
				System.out.println((char) cp + " is an alphabet");
				System.out.println((char) cp + " is not an alphabet");
		catch(Exception e) 
			System.out.println("Invalid Input!!");

Enter Unicode codepoint input: 101
e is an alphabet
Enter Unicode codepoint input: 48
0 is not an alphabet
