isa Test

[No One]

I've not done Java in a couple of years and I've been doing C# during
that time, so I know I mixing my languages a bit. What I cannot
remember how to do in Java is test an object for its type. In C# one
uses the "isa" keyboard, but I can't find something like this in Java.
Perhaps because I am having to use 1.2? The only thing I can think of
is to compare the objectInstance. class.getName() and
comparingObject .class.getName( ). This doesn't work for inheritance very
well. Any pointers would be greatly appreciated.

Use the "instanceof " keyword.

Thanks. I knew I was having a brain cramp.
