Write code to take a String input from the user, then print the first and last letters of the string on one line. Sample run: En

Ainat [17]

<h2>Answer:</h2>

//import the Scanner class to allow for user input

import java.util.Scanner;

//Begin class definition

public class FirstAndLast{

//Begin the main method

public static void main(String []args){

//****create an object of the Scanner class.

//Call the object 'input' to receive user's input

//from the console.

Scanner input = new Scanner(System.in);

//****create a prompt to tell the user what to do.

System.out.println("Enter the string");

//****receive the user's input

//And store it in a String variable called 'str'

String str = input.next();

//****get and print the first character.

//substring(0, 1) - means get all the characters starting

//from the lower bound (index 0) up to, but not including the upper

//bound(index 1).

//That technically means the first character.

System.out.print(str.substring(0,1));

//****get and print the last character

//1. str.length() will return the number of character in the string 'str'.

//This is also the length of the string

//2. substring(str.length() - 1) - means get all the characters starting

// from index that is one less than the length of the string to the last

// index (since an upper bound is not specified).

// This technically means the last character.

System.out.print(str.substring(str.length()-1));

} // end of main method

} //end of class definition
