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

answer; ///the above statement is (

answer; receiver;
