You cannot increase the size (length) of an arrays dynamically, a string array for example. So what we could do? Read about collections in Java.

Lesson: Interfaces (The Java™ Tutorials > Collections)

There are some tricky ways to do dynamic sizes handling in Java, bit not safe at all. So I suggest you not to go for such things.

Eranga has already given you the solution to variable sized arrays: Collections such as an ArrayList.

That's what I've told you. Changing the size of an array dynamically it problematic. That's why different implementations introduced in Java. Did you go through the like I've send to you?
