Please help me use/create Concurrent LinkedHashMap.
As per my belief, if I use Collections.synchronizedMap(), I would have to use synchronized blocks for getter/setter.
If I use ConcurrentSkipListMap, is there any way to implement a Comparator to store sequentially.
I would like to use java's built in instead of third party packages.
Thanks

write an interface with one method,two classes that implement the interface, and a main method with an array holding an instance from both classes.Using this array variable call the method in a foreach loop.This is a interview question in java anybody?
I was surprised to see in the Java source that System.arraycopy is a native method.
Of course the reason is because it's faster. But what native tricks is the code able to employ that make it faster?
Why not just loop over the original array and copy each pointer to the new array - surely this isn't that slow and cumbersome?
Thanks,
