Java toArray() method directly for Primitive Data Type.

How to use same method for String or Other Custom class list efficiently ?

Here is the simple solution.

Just pass the array Object with required size as a parameter to toArray();

Code snippet for String:

List <String> names = …..

……..

…….

names.toArray(new String [names.size()]);

Code snippet for Custom Class:

List<CustomClass> objects = ….

…………

………

objects.toArray(new CustomClass[objects.size()]);
