Answer 1

The problem is that you use 2 scanners for 1 input app (System.in) , and Java can't handle it like in your code, to correct the bug, just use one scanner (delete the second variable and use first to assign an int to v2)
Here is your code :
import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
System.out.println("enter first value");
Scanner first = new Scanner(System.in);
int v1 =first.nextInt();
System.out.println("enter second value");
int v2 =first.nextInt();
System.out.println(v1 + v2);

}
}

Input : 12 56
(you also may use line breaks to separate them)
Output : 68 (besides the other strings printed)
