Write a java program that will take 2 string inputs and perform the following operation on them: a) show length of the strings b) concatenate two strings c) convert those two strings to uppercase.

// here is code in java.

import java.util.*;

// class definition

class Solution

{

   // main method of the class

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

{

   try{

 // scanner object to read input from user

Scanner scr=new Scanner(System.in);

 // string variables

String st1,st2;

System.out.print("enter the first string:");

 // read the first string

st1=scr.nextLine();

System.out.print("enter the second string:");

 // read the second string

st2=scr.nextLine();

// part (a)

 // find length of each string

System.out.println("length of first string is: "+st1.length());

System.out.println("length of second string is: "+st2.length());

//part(b)

 // concatenate both the string

System.out.print("after Concatenate both string: ");

System.out.print(st1+st2);

// part(c)

 // convert them to upper case

System.out.println("first string in upper case :"+st1.toUpperCase());

System.out.println("second string in upper case :"+st2.toUpperCase());

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read two strings st1 and st2 with scanner object.In part a, find the length of each string with the help of .length() method and print the length.In part b, concatenate both the string with + operator.In part c, convert each string to upper case with the help of .toUpperCase()  method.

Output:

enter the first string:hello

enter the second string:world!!

length of first string is: 5

length of second string is: 7

after Concatenate both string: hello world!!

first string in upper case :HELLO

second string in upper case :WORLD!!
