Program Plan Intro

Program:

LinkedList.java:

  • Define a class “LinkedList”.
    • Define a “LinkedList()” constructor.
      • This generates an empty linked list.
    • Define a “getFirst()” method.
      • This function returns the first element in the linked list.
    • Define a “removeFirst()” method.
      • This function returns the removed element in the list.
    • Define a “addFirst()” method.
      • This function adds an element to the front of the linked list.
    • Define the “listIterator()” function.
      • This returns an iterator for iterating through this list.
    • Define a class “Node”.
      • Declare the packages for process.
    • Define a class “LinkedListIterator” which implements ListIterator.
      • Declare the local variables.
      • Define a constructor “LinkedListIterator()”.
        • This generates an iterator point to the front of list.
          • Define “next()” method.
            • This moves the iterator to next element.
            • Returns the traversed element.
          • Define a “hasNext()” function.
            • Checks if there is an element after the iterator position.
            • It returns true if there is an element.
          • Define a “add()” function.
            • This will add an element before the iterator position.
            • Then moves the iterator past to the inserted element.
          • Define a “remove()” method.
            • This function removes the last traversed element in the list.
          • Define a “set()” function.
            • This function set the last element to a different value.

ListIterator.java:

  • Define an interface “ListIterator”.
    • Declare the “next()”, “hasNext()”, “remove()” and “set()” functions.

Tree.java:

  • Define a class “Tree”.
    1. ○ Define a constructor “Tree()”.
      • It generates an empty tree.
    2. ○ Define a “addSubTree()” function.
      • This function adds an element as last child.
    3. ○ Define a “count()” method.
      • This function counts the number of leaf elements.
    4. ○ Define a “size()” method.
      • This computes the size of the tree.
      • Returns the number of non-null nodes.
    5. ○ Define a “listToString()” method.
      • This function converts list of lists as string.
    6. ○ Define a “toString()” method.
      • This function is used to convert to a string.

TreeTester.java:

  • Define a class “TreeTester”.
    • Define a “main()” function.
      • Create objects for the tree.
      • Add elements to the tree.
      • Print the tree and size of the tree.

How do we find the possible  final values of variable x in the following program.   Int x=0; sem  s1=1, s2 =0;   CO P(s2); P(s1); x=x*2; V(s1); // P(s1); x=x*x; V(s1); // P(s1); x=x+3; V(s2); V(s1); Oc
Lab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…
If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A. (a)  Give an example of when an application might want to receive such ICMP messages. (b)  Find out what an application has to do, on the operating system of your choice, to receive such messages. (c)  Why might it not be a good idea to send such messages directly back to the originating port P on A?
