Suppose we have a String object called myString. Write a single line of Java code

that will output myString in such a way that all of its characters are uppercase.

myString=myString. toUpperCase ();

Explanation:

In java to change all characters of a string to upper case we use. toUpperCase () method. It will convert string to upper case.

Implementation in java.

import java. util.*;

class Solution

{

public static void main (String[] args) throws java. lang. Exception

{

try{

Scanner scr=new Scanner (System. in);

System. out. print ("Enter a string:");

String myString=scr. nextLine ();

myString=myString. toUpperCase ();

System. out. println ("string in upper case : "+myString);

}catch (Exception ex) {

return; }

}

}

Output:

Enter a string:hello

string in upper case : HELLO
