You don't have to mess with reallocation in Java. That is what the garbage collector is for.
//creates an array of 10 objects.
Object[] someObject = new Object[10];
//sometime later old array is discarded, and new 12 element array is created.
someObject = new Object[12]; //Garbage collector will reallocate the memory from the discarded array. Not your problem.
