Debug the code in the main method of this class, which is intended to initialize an array named arr to hold 3 ints, fill this with 3 inputs from the user, then print the contents of the array in order followed by the sum. Here's the code that needs to be fixed:

import java. util. Scanner;

public class U6_L1_Activity_One{
public static void main(String[] args){
Scanner scan = new Scanner(System. in);
int[] arr = new int(3);
arr[1] = scan. nextInt();
arr[2] = scan. nextInt();
arr[3] = scan. nextInt;
System. out. println("Contents: " + arr{1} + " " + arr{2} + " " + arr{3});
System. out. println("Sum: " + arr[1] + arr[2] + arr[3]);
}
}

import java.util.Scanner;

public class U6_L1_Activity_One{

 public static void main(String[] args){

   Scanner scan = new Scanner(System.in);

   int[] arr = new int[4];

   arr[1] = scan.nextInt();

   arr[2] = scan.nextInt();

   arr[3] = scan.nextInt();

   System.out.println("Contents: " + arr[1] + " " + arr[2] + " " + arr[3]);

   int Sum = (1 + 2 + 3);

   System.out.println("Sum: " + Sum);

 }

}

Explanation:

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.
