Write Java code for extending the ArrayList class of java.util.* to ExtArraayList that includes the following one method: public boolean equals(ExtArrayList eal) // returns true if the values in this list is the same as in eal. For instance, if E is Integer and this has {2,1,3,1,6} and eal has {1,2,3,1,6} then you should return true. If eal has {1,2,3,6}, you should return false. Clearly the size of each should be the same but obviously there is more to it than that. You can assume the existence of equals() method for testing equality of E. Do not use specific types like String or Integer. Estimate the run-time complexity of the methods assuming the size of the list is n.
