Write a Java method removeDuplicates that removes all duplicates in a given list

a. The method accepts an object of type List
b. The return type of the method is void
c. Duplicates are determined using the equals() method (rather than by the == operator)
Your implementation of removeDuplicates should handle, in an appropriate way, the case in which a null List is passed in to the method.
Test your method by writing code in a main method, which does the following:
a. It creates an instance of List and loads it with the following Stringvalues:{“good”, “better”, “best”, “best”, “first”, “last”, “last”, “last”,”good”}
b. It invokes the removeDuplicatesMethod, passing in this instance of List
c.  It outputs the modified list to the console
