can array size defined dynamically?

[Davie Lin]

Hi, Happy Holiday everyone

Does anyone know if array size in Java can be defined dynamically with an integer variable.

Would be great if you can just write a couple lines of code to demonstrate if it is possible.

Thank you

Well, have you tried it? Try to create an array with statically defined size. Then, try to declare it's size as an int variable and use it as the array's size. What happens?

Yes. you can. please go through the documentation about Arrays.copyOf and System.arrayCopy
