Calling a method inside another method in same class

Question

In page 428 (the chapter about Type Information) of his \"Thinking In Java, 4th Ed.\", Bruce Eckel has the following example:

public class Staff extends Arra         


        

Answer 1

Java implicitly assumes a reference to the current object for methods called like this. So

// Test2.java
public class Test2 {
    public void testMethod() {
        testMethod2();
    }

    // ...
}

Is exactly the same as

// Test2.java
public class Test2 {
    public void testMethod() {
        this.testMethod2();
    }

    // ...
}

I prefer the second version to make more clear what you want to do.
