Arrays

Java Arrays class is a utility class provided by Java to manipulate arrays. It contains various methods to sort the array, search the array and fill the array with specified elements.

The Arrays class is contained in the java.util package, so you have to import java.util.Arrays class to use it in the code.

Arrays class also provides asList method which allows us to use an array as a List. This method returns a fixed sized List backed by the original array.

Here are some of the methods of Java Arrays class which are very useful.
1) sort

6) copyOf
The static copyOf method allows us to copy elements of an array to another array.
