Can't Remember How to Do This

In programming class, we just learned some very simple java. However, now I can't remember the code! Can someone tell me what I'm doing wrong?
import javax.swing.JOptionPane;


public class InputOutput {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

System.out.println("Hello World!");//Output
int num1;
int num2;
int sum;
string input1;
string input2;

System.out.println("Enter an integer.");
input1=JOptionPane.showInputDialog("Input an integer...");
input2=JOptionPane.showInputDialog("Input another.");
num1=Int.parseInt(input1);
num2=Int.parseInt(input2);
sum=num1+num2;
System.out.println("The sum is"sum);

}

}

You need to fix the following:

- Add the code

Code:

---

Import javax.swing*;

---

to the top of the class because you're using JOptionPane from the Swing libarary.

- The String Class is always spelt with a capital S, like all class names.

-

Code:

---

[B]Integer[/B].parseInt(input1);

---

Not

Code:

---

Int.parseInt(input1);

---

(int is a prmitive data type while Integer is an Object wrapper class)

-and lastly you need to use the + sign to add something to a String like:

Code:

---

System.out.println("The sum is " [B]+[/B] sum);

---

Hope that helps.

Thanks! I figured it was something like this.
