incompatible types required: int found: java.lang.String (basic programming)

I have come across this error a few times, and I try many things to fix it, but I can't seem to find out what is going wrong. here is the code:

import java.util.Scanner;
public class InputExample {
    public static void main(String[] args) {

        Scanner scan = new Scanner(System.in);
        String name1 = scan.nextLine();
        String name2 = scan.nextLine();
        int num1 = scan.nextLine();
        double num2 = scan.nextLine();

        System.out.println("Employee Name:" + name2 + name1);
        System.out.println("Age:" + num1);
        System.out.println("Salary:" + (double)num2);
    }
}

And the error that shows up specicfically is:

[File: /InputExample.java Line: 9, Column: 25] incompatible types required: int found: java.lang.String

[File: /InputExample.java Line: 10, Column: 28] incompatible types required: double found: java.lang.String

You're reading in a String, but want to save it as Integer/Double. Try this:

int num1 = Integer.valueOf(scan.nextLine());

Same goes for Double.

Or as OldCurmudgeon mentioned:

int num1 = scan.nextInt();
