Arrays are not objects, so we can’t invoke methods on them. This can make it awkward to, for example, test two arrays for equality. The built-in java. util. Arrays class provides several static methods that work on arrays. Look this class up in the API. Explain the difference between the equals() and deep Equals() methods and between the to  String() and deep To String() methods. (If you use it in code, you must refer to the Arrays class as java. util. Arrays, for reasons explained in Chapter 3.)
