Java...am i using 'this' correctly?

Running into problems and I'm wondering if I'm using this correctl开发者_StackOverflowy.

Is this ok?

public person{
.
.
.
    public void setmother(person mom){
        mom.addchild(this);
    }

I'm created a personb class. Inside setmother, I want to use a method that adds children to the class. I want to add the current instance of the class to the array of children in the mom instance of the class.

I don't even know if I have the lingo down...hopefully someone understands what I'm trying to do!

Your code looks fine as it stands, i.e. you are using "this" correctly.

It's probably a good idea to also set a field that points from the child to the mother - otherwise it can be hard to implement a corresponding "getMother" method in the future, i.e. something like:

public class Person {
    private Person mother;
.
.
.
    public void setMother(Person mom){
        mom.addChild(this);
        mother=mom;
    }
.
.
}

The other minor thing I would change is the naming convention in order to be more in line with usual Java style:

• person => Person (class names start with capitals)
• setmother => setMother (method names start with lowercase but use capitals for following words)
• addchild => addChild

Yes, you are using this correctly, apart from it not being called "self", and regardless of the other syntax errors in the above code.
