and this is the program

import java.util.Scanner;
public class Tutorials

public static void main(String args[]) {
Scanner bucky = new Scanner(System.in);

fnum = bucky.nextDouble();
System.out.println("Enter second num:");
snum = bucky.nextDouble();
answer = fnum + snum;
System.out.println(answer);




}


}

Answer 1

fnum is not declared so has no type.

snum is not declared so has no type.

answer is not declared so has no type.



Your good at this aren't you.



Have fun.

Answer 2

You didn't declare your variables! Should look like this:



import java.util.Scanner;

public class Tutorials



public static void main(String args[]) {



double fnum, snum, answer; // you have to declare your variables



Scanner bucky = new Scanner(System.in);

System.out.println("Enter first num:");

fnum = bucky.nextDouble();

System.out.println("Enter second num:");

snum = bucky.nextDouble();

answer = fnum + snum;

System.out.println(answer);



}//end main

}//end class

Answer 3

Like the error message says, you're trying to use variables called fnum, snum, and answer, but you haven't declared any variables with those names.

Answer 4

you didn't declare the variables fnum, snum and answer
