For general stuff relating to OOP you'll often find that you're better off with a Google search on Java,

You can set the variable to null, if you want to, like

instanceName = null;

Afterwards, the garbage collector, which frees unused memory, will at some point in time recover the memory.

However, I don't think you need to do this as long as you're not working with static instances.

You can also avoid to declare your instance global.

But sometimes you can not do otherwise.

so deleting isnt a good idea then ;)

I found out you can re-instantiate constructors like below which is good enough for me.

Bla b = new Bla("cheese");

...do some stuff with b...

b = new Bla("mat");

...do some more stuff with b...

thanks for pointing me in the right direction :)
