TASK 3. Console Input and Output. Review Scanner class and its methods, Implement the following code, make sure it runs without errors. 1 package 1lessons; 3 import java.util.Scanner; 4 5 public class ReportSum3 { public static void main(String args[]) { Scanner sc = new Scanner(System. in); 60 7 8 // Prompt the user to enter the first integer System.out.println("Enter the value for 'a' and press Enter: "); int a = sc.nextInt(); // Prompt the user to enter the second integer System.out.println("Enter the value for 'b' and press Enter: "); int b = sc.nextInt(); 10 11 12 13 14 15 16 17 18 19 20 21 22 } //Close the Scanner. It's a good practice to release the resource that was acquired sc.close(); // Display the result System.out.printf( "Provided Integers: %4d and %4d, the total is %5d\n", a, b, (a + b)); } To simplify the task, we came out with the idea to use Methods. Implement a method to add two integers.
