getter methods

Also known as accessor methods, getter methods just return the value of a field in a class.

class TwoDPoint {
    double x;
    double y;
    
    String getAsString() {
      return "(" + this.x + "," + this.y + ")";
    }
    
    void setX(double value) {
      this.x = value;
    }
    
    void setY(double value) {
      this.y = value;
    }
    
    double getX() {
      return this.x;
    }
    
    double getY() {
      return this.y;
    }
  
}
TwoDPoint origin = new TwoDPoint();
origin.setX(0.0);
origin.setY(0.0);
System.out.println("The x coordinate is " + origin.getX());
