Q:

Where can I find the source code for Java arrays?

Where can I find the source code for java arrays?
Example:
double[] arr=new double[20];

All array's with any dimension implements Cloneable and Serializable` interface. I searched the source code but couldn't find the code for this.

A:

Have a look at this for an explanation. But basically the array type is built-in to the jvm and you need to analyze the source code for the jvm you are running in order to truly know how it works.

A:

Here is the javadocs for java.util.Arrays and here is the implementation of java.util.Arrays in openjdk. Google Code search is a good way to go about it.
UPDATE 1: Link updated. Posted the wrong link.
UPDATE 2: As pointed out by thilo, the jvm implementation of Array is here
