Java rectangle cannot find symbol

import java.awt.Rectangle;
public class Rec {

public static void main(String[] args) {
   Rectangle r1;
   r1 = new Rectangle(2, 5, 15, 15);
   System.out.println(r1.getHeight);
}
}

and i get an error like:

System.out.println(r1.getHeight);
                        ^
symbol:   variable getHeight
location: variable r1 of type Rectangle
1 error

I don't get what is wrong with this code, I'm new user so it may be simple but I couldn't find the problem :(

Use r1.getHeight() instead of r1.getHeight because getHeight(); definded in Rectangle class . use for Gets the bounding Rectangle of this Rectangle. Link

To invoke a Java method (and Rectangle.getHeight() is a method), you need a parentheses, like:

System.out.println(r1.getHeight());

By the way, for a method that accepts arguments, you would put those arguments in between parentheses:

// This is a method declaration. It says it returns an integer
// and it accepts two integers as its arguments.
int addTwoNumbers(int a, int b) {
  return a + b;
}

// Somewhere in the code, you could call this method by passing
// two integers in there:
int number1 = 1;
int number2 = 10;
int result = someobject.addTwoNumbers(a, b);
// result is now 11.
