<u>The different between 32 bit and 64 bit version:</u>
- The main difference between 32-bit and 64-bit versions is that a 32-bit version can access
memory addresses which is roughly equivalent to 4 GB of memory.
- On the other hand, a 64-bit version can access
memory addresses which equates to a huge amount of memory, 16 exabytes to be precise.
- Nowadays, we observe that almost all the computers have 64-bit processors, which means that they can access any amount of memory over 4 GB till 16 exabytes.
- 64-bit processors have various advantages like the increased speed of operations, smooth multitasking and they can also support video games and software's that have high graphical requirements.
<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
