Java program to convert string to lowercase and uppercase using String function

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.

Java Code:

/* Program to enter a string and display in both UpperCase and LowerCase using String function.*/\nimport java.util.*;\r\nclass DisplayCase\r\n{\r\npublic static void main()\r\n{\r\nScanner inp=new Scanner(System.in);\r\nSystem.out.print(\"\\n Enter String: \");\r\nString s=inp.nextLine();
\nSystem.out.println(\"\\n Upper Case: \"+(s.toUpperCase()));\r\nSystem.out.println(\"\\n Lower Case: \"+(s.toLowerCase()));
\n}\r\n}\r\n

Output:

Enter String: The Big Bang Theory\nUpper Case: THE BIG BANG THEORY \nLower Case: the big bang theory \nEnter String: FrIenDs \nUpper Case: FRIENDS \n

Lower Case: friends
