The easiest way to transform collection to array?

Question

Suppose we have a Collection. What is the best (shortest in LoC in current context) way to transform it to Foo[]? Any well-known

Answer 1

For example, you have collection ArrayList with elements Student class:

List stuList = new ArrayList();
Student s1 = new Student("Raju");
Student s2 = new Student("Harish");
stuList.add(s1);
stuList.add(s2);
//now you can convert this collection stuList to Array like this
Object[] stuArr = stuList.toArray();           // <----- toArray() function will convert collection to array
