code explanation

[jacob deiter]

Anyone please expalin the code below,what this code says

class h {

Fa fa = new Fa() {

public Object make() {
return new js();
}
};

}

[David O'Meara]

It doesn't look like it compiles.

Where did you get that from? It is full of all sorts of stylistic unconventialities. If you are copying from books or website, please Quote Your Sources.

You need to have a class js with a no-arguments constructor, and a class Fa, then it is actually very similar to this thread. It is an anonymous subclass of Fa with a make() method.

If you say "stylistic unconventialities" again I may need to pay someone to smack you

Can I choose who it is? As long as it isn't Rob.

Shall we get back to the official subject of this thread?

Dear all

I do not want to know whether it will complie or not.It is part of successful code,I just want explanation,you all think that it is a pseudo code.

The answer has been given.

It is creating in instance of a subclass of Fa that is anonymous (it has no name). The subclass contains one method that has been customized.


Standard:

foo = new Foo();

Anonymous Subclass:

foo = new Foo() {
 myCustomMethodInMyCustomSubclass() { /* code */ }
};

you normally don't see this in hand-coded Java,
but you often see it in machine-generated Java code,

If the question was about who was going to kick you, you'd beg for me to do it. I still have just a little power in my kicking leg

Then you haven't seen my code. Especially in user interface programming I do it all the time:

Action action = new AbstractAction("Action")
{
    ...
};
TableModel model = new DefaultTableModel(...)
{
    public Class getColumnClass(int column)
    {
        ...
    }
 
    public boolean isCellEditable(int row, int column)
    {
        ...
    }
};

And yes, I code 90% of my code by hand. The only code I let Eclipse generate for me is getters and setters, and even those I tweak to get at least the Javadocs correct. "Sets the myField"... ARGH!
