    Default need help about java class and object


    I'm new to java and heres my question: What does it mean by this:
    private Classx Objx;
    Objx = SomeClass.getStuffx().getStuffz();<--???what does this mean???

    I think I understand when it says "SomeClass.getStuffx();". It means that it's calling the method "getStuffx()" which is inside the class "SomeClass". But what does this mean "SomeClass.getStuffx().getStuffz();"????

    That's simply chaining method invocations. It basically says, "Take the object returned by getStuffx() and invoke that object's getStuffz() method."

    The purpose is to cut down on explicitly defining variables to hold the result of every method invocation.
