Common Ancestor to Java Array and List

Question

In .NET, both array and list have Enumerable as ancestor, so a method that accept Enumerable as an argument can receive both array and list as its argument. I wonder if ther

Answer 1

They don't have a common ancestor, however, there are methods to cast between the two types as needed -

• List.toArray()
• Arrays.asList()

So you could provide an overloaded method to cast to a common type - i.e.

public void doAll(MyType[] array) {
    doAll(Arrays.asList(array));
}

public void doAll(List list) {
    //... process List here.
}
