Create a new array with given size, if size is different than given array. Copy as much as possible data of the given array into the new array. If new array is larger than given array, the empty space is not initialized.

The effect is that of the equivalent array creation expression: new cl[size] and copying of existing data into this new array.

Parameters:

cl - class of objects in data array.

data - source array, may be null.

size - size of new array

Parameters:

data - source array, may be null.

size - size of new array

Version:
