in java

Define a class ArraySetWithResizableArrayBag that represents a set and implements the SetInterface (described in Segment 1.21 of chapter 1). Use the class ResizableArrayBag in your implementation as defined in the UML diagram below: the instance variable setOfEntries is defined as ResizableArrayBag object. Test your class with the test cases provided in main. Load to IDEA only the classes needed for this project from the provided Lab02.zip file. Make sure that the DEFAULT_CAPACITY in ResizableArrayBag is set to 3.

Most of the methods can be implemented by simply calling appropriate methods from the ResizableArrayBag, for example the clear method would be implemented as:

THE TODO Sections

public void clear() { this.setOfEntries.clear(); }  

NOTE: 

1. Ensure that your add method does not allow duplicates and checks for null entries.

2. The third constructor: public ArraySetWithResizableArrayBag(T[] contents) must call your add method to populate this.setOfEntries with elements from the passed contents array (check for null elements!).
