I switched from C++ to Java and have a problem with nested classes. I would like to initiate an instance of a subclass in the constructor of the superclass. I tried it like this, but it seems to be wrong.
public class Aircraft { public class LandingGear { } public Aircraft() { Aircraft.LandingGear myLandingGear = this.new LandingGear(); } }
The idea is that every instance of the class Aircraft has an instance “myLandingGear” of the subclass LandingGear.
Answer
Every Aircraft will have a LandingGear
public class Aircraft { private LandingGear myLandingGear; public Aircraft() { myLandingGear = new LandingGear(); } public LandingGear getLandingGear() { return this.myLandingGear; } }
