Thinking in Java Fourth Edition Bruce Eckel Chapter 4 Exercise 8

Exercise 8: Create a class with two methods. Within the first method, call the second method twice: the first time without using this, and the second time using this—just to see it working; you should not use this form in practice.

class Doc
{  
    void intubate()
    {
        System.out.println("prepare patient");
        laryngoscopy();
        this.laryngoscopy();   
    }
    void laryngoscopy()
    {
        System.out.println("use laryngoscope");
    }  
}  
public class PassingThisEx
{  
    public static void main(String[] args)
    {
        new Doc().intubate();      
    }      
}
