Answer 1

//TestCode.java
import java.util.Scanner;
public class TestCode {
    static int getResult(int num1, int num2, int num3){
        int res = 1;
        if(num1 == 7){
            res = 1;
        }
        else{
            res = res * num1;
        }
        if(num2 == 7){
            res = 1;
        }
        else{
            res = res * num2;
        }
        if(num3 == 7){
            res = -1;
        }
        else{
            res = res * num3;
        }
        return res;
    }

    public static void main(String[] args) {
        int num1, num2, num3;

        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter value for num1: ");
        num1 = scanner.nextInt();

        System.out.print("Enter value for num2: ");
        num2 = scanner.nextInt();

        System.out.print("Enter value for num3: ");
        num3 = scanner.nextInt();

        System.out.println(getResult(num1,num2,num3));
    }
}
