Answer:
// here is code in java.
import java.util.*;
class Main
{
public static void main (String[] args) throws java.lang.Exception
{
try{
// create 3 string variables
String st1,st2,st3;
// scanner object to read input
Scanner scr=new Scanner(System.in);
System.out.print("enter the first string:");
// read first string
st1=scr.nextLine();
System.out.print("enter the second string:");
// read second string
st2=scr.nextLine();
// print 1st string and its length
System.out.println(st1+" "+st1.length());
// print 2nd string and its length
System.out.println(st2+" "+st2.length());
// create 3rd string by joining two string with a space between
st3=st1+" "+st2;
//// print 3rd string and its length
System.out.println(st3+" "+st3.length());
}catch(Exception ex){
return;}
}
}
Explanation:
Create three string variables.Read the 1st string and assign it to variable "st1" , read 2nd string and assign it to variable "st2".Find the length of 1st and 2nd string and then print "st1" & its length.Similarly do it for 2nd string, print "st2" and its length in a line. Join the first two string with a space in between them. find its length and print the "st3" and its length in a line.
Output:
enter the first string:
hello
enter the second string:
alex
hello 5
alex 4
hello alex 10
