Why does x.equals(y) throw an error in Java?

Question

Why does this program throw an error?
public class Program
{
public static void main(String[] args) {
int x=5;
int y=8;
System.out.println(x.equals(y));
}
}

Answer 1

Konsel
equals() method is a method which is inherited from the Object class.
int, char, double and so on are primitive datatypes. Here you can use == to compare them.
But all of them have a wrapper class.
int -> Integer
char -> Character
double -> Double
and so on...
You can do this:
Integer x = 5;
Integer y = 8;
System.out.println (x.equals (y));

Thank you very much! Sorry didn't realize that they wrote "Integer" instead of int...
And thanks for the explanation!
Now it works!
