In this post, I will be sharing how to check if a Character is Lowercase or not in Java. We can easily achieve our goal of checking if a Character is Lowercase or not by using the Character.isLowerCase() method.

1. Using Character class isLowerCase() method

According to Oracle docs, the Character.isLowerCase() method can be used to determine if the specified character is a lowercase character.

The following are examples of lowercase characters:

a b c d e f g h i j k l m n o p q r s t u v w x y z
'\u00DF' '\u00E0' '\u00E1' '\u00E2' '\u00E3' '\u00E4' '\u00E5' '\u00E6'
'\u00E7' '\u00E8' '\u00E9' '\u00EA' '\u00EB' '\u00EC' '\u00ED' '\u00EE'
'\u00EF' '\u00F0' '\u00F1' '\u00F2' '\u00F3' '\u00F4' '\u00F5' '\u00F6'
'\u00F8' '\u00F9' '\u00FA' '\u00FB' '\u00FC' '\u00FD' '\u00FE' '\u00FF'

Note: Character.isLowerCase() method cannot handle supplementary characters.

Java Program

public class CheckCharacterLowercase {
    public static void main(String args[]) {
        char ch = 'a';
        if(Character.isLowerCase(ch))
        {
            System.out.println("Given character is Lowercase");
        }
        else
        {
            System.out.println("Given character is NOT Lowercase");
        }
    }
}

Output:
Given character is Lowercase

That's all for today. Please mention in the comments if you know any other way of checking if a character is lowercase or not in Java.
