CODE IN JAVA

Write a generic interface of type T called Set with the following abstract methods: boolean add(T element) void remove(T element) boolean contains(T element) void union(Set otherSet).

The generic Set interface represents a data structure with unique elements only. In a Set data structure, method add (), will get an element as an argument, and if that element does not exist inside the set, will add it and return true. If it exists, will ignore the element and return false. Method remove (), will get an element as an argument, and if that element exists inside the set, will remove it. If it does not exist, will ignore the element. Method contains(), checks whether the given argument exists inside the set. Method union(), takes another set as an argument and will merge the two sets into one (without breaking the uniqueness of the Set).

Write a concrete class called MySet that implements the Set interface. use an array list to store the elements inside the set.
