All Implemented Interfaces:

java.util.Collection, java.util.List, java.io.Serializable

public class UnmodifiableArrayList

extends java.util.AbstractList

implements java.io.Serializable

An unmodifiable view of an array. Invoking

new UnmodifiableArrayList(array);

is equivalent to

Collections.unmodifiableList(Arrays.asList(array)));

But this class provides a very slight performance improvement since it uses one less level of indirection.

public int size()

Returns the list size.

Specified by:

size in interface java.util.List

get

public java.lang.Object get(int index)
