if (newCapacity - MAX_ARRAY_SIZE > 0) newCapacity = hugeCapacity(minCapacity); Check if array size reached MAX_ARRAY_SIZE (which is Integer.MAX - 8) Why the maximum array size of ArrayList is Integer.MAX_VALUE - 8? Finally it copies old values to the newArray with length 15 Share...
If you aware of the number of elements that you are going to add toArrayList, you can initialize it with an initial capacity. This avoid resizing overhead. importjava.util.ArrayList; publicclassArrayListExample{ publicstaticvoidmain(String[]args){ ...
