Write a program that the following methods:

$1$ contains: this method takes an array of integers and an int x$,$ and returns true if the array contains the value x$,$ and false otherwise.

Example: if the array had the values $\{2,7,3\}$ and x $=7$ then the method returns true. But if x $=0$ then the method returns false.

$2$ reverse: this method takes an array of integers and returns a new array that is the reverse of the parameter.

Example: if the array $=\{6,2,9,5\}$ then the method returns an array with the values reversed $\{5,9,2,6\}.$

$3$ equals: this method takes $2$ integer arrays and returns true is both arrays are equal and false otherwise.
