Data structure in java | Computer Science homework help

The files in the lab2 directory contain classes for two different types of

doubly-linked list.  The DList1 class does not use a sentinel, whereas the

DList2 class does.  The DList1 class is not circularly linked, but the DList2

class is (through the sentinel).  Compile DList1.java and DList2.java (using

“javac -g DList1.java DList2.java”.)

Your task is to implement two insertFront() and two removeFront() methods–one

of each for each list class.  insertFront() and removeFront() insert or remove

an item at the beginning of a list.  Make sure your implementations work for

empty lists, one-node lists, and larger lists.

The main() methods of DList1 and DList2 include test code, which you can run

with “java DList1” and “java DList2”.

Part I:  insertFront in DList1 (1 point)

—————————————-

Write a method called DList1.insertFront() that inserts an int at the front of

“this” DList1.

Part II:  removeFront in DList1 (1 point)

—————————————–

Write a method called DList1.removeFront() that removes the first item (and

node) from “this” DList1.

Part III:  insertFront in DList2 (1 point)

——————————————

Write a method called DList2.insertFront() that inserts an int at the front of

“this” DList2.  Your code should NOT use any “if” statements or conditionals.

Part IV:  removeFront in DList2 (2 points)

——————————————

Write a method called DList2.removeFront() that removes the first item (and

non-sentinel node) from “this” DList2.  Your code should not require separate

branches for the one-node case and the more-than-one-node case.  (You will

need one “if”, to handle the zero-node case.)

Check-off

———

Run the DList1 and DList2 test code.

1 point:  DList1.insertFront().

1 point:  DList1.removeFront().

1 point:  DList2.insertFront().

1 point:  DList2.removeFront().
