ArrayUtils.toString() is a great way to display the values of simple data types. For more complex data types, like JavaBeansW, you can use ArrayUtils.toString() in conjunction with ToStringBuilder.reflectionToString() in the toString() method of your complex data type to display the values of your objects in your array.

the ArrayTest class contains an inner class called TestClass.
I wonder why author used inner class in this case. please advise
In this (simple) case TestClass could have been perfectly a "global" class too.
When should inner classes be used in Java?

I wonder what is a need for inner class even after reading the link you posted.
That article gives a nice example. I can't do any better. Sorry.

Java
Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
