public class CharacterExample2 {
public static void main(String[] args) {
char uppercaseChar = ‘H’;
// Convert to lowercase
char lowercaseChar = Character.toLowerCase(uppercaseChar);
System.out.println(“Uppercase: “ + uppercaseChar);
System.out.println(“Lowercase: “ + lowercaseChar);
// Convert back to uppercase
char originalUppercaseChar = Character.toUpperCase(lowercaseChar);
System.out.println(“Original Uppercase: “ + originalUppercaseChar);
}
}
Output:
