Here, we are supposed to create a source code that asks for String input from the user and displays the string by changing the String’s Case to both UpperCase and LowerCase.

The basic idea is to change the input string’s case using String functions <String>.toUpperCase() for upper case modification and <String>.LowerCase() for lower case modification.

Source Code:

/* Program to enter a string and display in both UpperCase and LowerCase using String function.*/

import java.util.*;
class DisplayCase
{
public static void main()
{
Scanner inp=new Scanner(System.in);
System.out.print("\n Enter String: ");
String s=inp.nextLine();

System.out.println("\n Upper Case: "+(s.toUpperCase()));
System.out.println("\n Lower Case: "+(s.toLowerCase()));

}
}

Output:

Enter String: The Big Bang Theory

 Upper Case: THE BIG BANG THEORY

 Lower Case: the big bang theory


 Enter String: FrIenDs

 Upper Case: FRIENDS

 Lower Case: friends
