Thumps up als je door dhr. Melles hier naartoe gestuurd bent omdat hij te lui is om het zelf uit te leggen.

@GutGenotype I believe vector is a shape or variable. ArrayList is like array but it stores reference variables to classes. By this i mean TestClass TC = new TestClass(); can be stored in arraylist.

This advantage of array list is that once you reach your size limit you can still add objects to it and it will increase in size. For array you basically have to remake the array if you add to much to it then you lose all the old array data unless you save it some where.

Don't know about vectors.

Thank you this was helpful to me.

I'm making a program and i personally rarely use arraylist so i'm having to relearn it now that i need it. This doesn't totally help me but at least i can hit the ground running.
