scanner and int issue

i get error incomparable types java.lang.String and int


how can i connect the two -.- been stuck on this lol

Code :

---

package whileloops;
import javax.swing.JOptionPane;
 
public class Whileloops {
 
 
public static void main(String[] args) {
 
  String omar;
  omar=JOptionPane.showInputDialog("First Number", "Enter Your First Numbe");
 
  if (omar == 2)  {System.out.println("I love you");
  toString(omar);
 
  }
 
 
 
}
}

---

You have declared omar as a String, and showInputDialog() will return you a String. Now a string is not a numeric value so you cannot say if(omar==2) which is what the compiler is grumbling about.

Now strings *are* associated with numeric values - "42" and "0x2A"with 42, "the only even prime" with 2 etc. And Java provides methods for the finding the first sort of association.

Basically you ought to declare another variable (an int) and use the string omar to give it the right value. And then use this int variable in the if condition. See Converting Between Numbers and Strings in Oracle's Tutorial for an example and discussion. Their example uses float rather than int, but the idea is the same.

great advice, thanks =)

You're welcome
