Problem with condition

Hi, I'm having problem with this code.

Code :

---

import java.io.*;
public class ConditionalStatement {
    public static void main(String[]args) {
 
        BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
 
        String num;
 
        try {
            num = input.readLine();
            int num1 = Integer.parseInt(num);
 
            int x=(num1>=0)? "positive":"negative";
            System.out.println("The number entered is "+x+".");
        }
 
        catch (IOException e) {
            System.out.println("Error!");
        }
 
        }
}

How come this line says "incompatible types"?

Code :

---

int x=(num1>=0)? "positive":"negative";

---

I just declared x as integer. What's wrong with that?

you are using ternary statement(operation), so i guess its a bit confusing.. ,,well the problem is this -- if num1 is greater than or equal to '0' then "ASSIGN" this String value to the variable 'x' which is an integer...


change the variable 'x' to String

In the code you have.

Code :

---

int x=(num1>=0)? "positive":"negative";

---

You are trying to check the value of num1 and return a string and assign it to int x. Change the int x to be String x.

Thanks for answering, and thanks for the instruction. Now the problem is, it does not output the "negative" even if I input -1 or any negative number. It always displays "positive".

Rewrite it to be this.

Code :

---

String x=(num1 >= 0 ? "positive" : "negative");

---

I think your parenthesis was in the wrong place.

This code works fine for me.

Code :

---

        int num1 = -1;
        String x = (num1 >= 0 ? "positive" : "negative");
        System.out.println(x);
