The toLowerCase() method converts a string to lower case letters. Note: The toUpperCase() method converts a string to upper case letters
public class Test {
public static void main(String args[]) {
System.out.println(Character.isLowerCase('c'));
System.out.println(Character.isLowerCase('4'));
System.out.println(Character.isLowerCase('
'));
System.out.println(Character.isLowerCase(' '));
}
