Thread: Problem with condition

Hi, I'm having problem with this 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"?

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

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

In the code you have.

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.

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

I think your parenthesis was in the wrong place.

This code works fine for me.

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