Question

public class Horse extends Animal {
    private Halter myHalter = new Halter();
    public void tie(LeadRope rope) {
        myHalter.tie(rope); // Delegate tie behavior to the
      // Halter object
    }
}

public class Halter {
    public void tie(LeadRope aRope) {
    // Do the actual tie work here
}
}

In this example Horse has-a Halter.Can we call myHalter.tie(rope); like this:

public class Horse extends Animal {
    private Halter myHalter = new Halter();

        myHalter.tie(rope); // Without using the public void tie method

}

It gives an error. My explanation to this is that its not a main() method but could anyone explain it in a better way.

Answer 1

Statements other than variable/field declarations in a class body must be put into a method body, a constructor or an initializer block. For example, it would be OK if you attempt to compile this code:

public class Horse {

    private Halter myHalter = new Halter();

    {
       myHalter.tie(new LeadRope());
    }
}
