for this lab, you will use the bag of integers from the lecture (linkedlist implementation intlinkedbag.java and intnode.java). a bag of integers is similar to an imaginary bag: it’s a container that holds a collection of integers that we place into it. a bag of integers can be used by any program that needs to store a collection of integers for its own use. for example, a program that keeps track of the ages of your family’s members. if you have a large family with 10 people, the program keeps track of 10 ages—and these ages are kept in a bag of integers. write a new static method for the intlinkedbag.java class with following signature: public static intlinkedbag removerepetition (intlinkedbag b1)
