Write a Java program from scratch that meets the following requirements:

a. The program is in a file called Duplicates.java that defines a class called

Duplicates (upper/lower case matters)

b. The program includes a Java method called noDuplicates that takes an array

of integers and returns true if all the integers in that array are distinct (i.e., no

duplicates). Otherwise it returns false. Make sure the method is public

static.

example tests:

noDuplicates({}) returns true

noDuplicates({-1, 1}) returns true

noDuplicates({4,22,100,99,1,5,7}) returns true

noDuplicates({4,22,100,99,22,5,7}) returns false

c. The programs main method calls noDuplicates on the above test cases and

prints each return value.

d. In a comment within Duplicates.java, give the sequence of steps you took to

solve this problem. Dont forget to talk about anything you did before writing

code, as well as any testing you did.
