Check if a String Contains only Alphabets in Java?

There are following way to check if a String Contains only Alphabets in Java.

• Declare A method checkAlphabet() to check if a String Contains only Alphabets in Java.
• Inside that method use regular expression regex [A-Za-z]*$ to validate String contain only alphabetic characters.
• Now return the Boolean status to print output.

public class TestAlphabet {
	public static void main(String[] args) {
		String str = "Welcome";
		boolean status = checkAlphabet(str);
		System.out.println("String contain only alphabet:- " + status);
	}

	public static boolean checkAlphabet(String str) {
		return (!str.isEmpty() && str != null && str.matches("[A-Za-z]*$"));
	}
}
