Program Plan Intro

Birds Survey

Program Plan:

  • Import required package.
  • Define “BirdSurvey” class.
    • Create object “headNode” from “ListNode”.
    • Create constructor for “BirdSurvey” class.
    • Define the method “getReport()”.
      • Compute position of node.
      • Check condition using “while” loop.
        • Display bird name and count.
    • Define the method “computeLength()”.
      • Set count to “0”.
      • Set “position” to “headNode”.
      • Check condition using “while” loop.
        • Increment count
      • Finally returns count value.
    • Define the method “addANodeToStart” which is used to add bird name at start of list by using “ListNode” class.
    • Define the method “add” with the argument of “bird”.
      • If head node is null, then add bird to the front of list.
      • Otherwise
        • Compute given bird name by calling the method “find” and then store result to “n”.
        • If “n” is null, then increment count value.
        • Otherwise, find the last node in the list.
      • Add in the node by using “ListNode” class.
    • Define the method “getCount” with the argument of “bird”.
      • Declare required variable.
      • Create list for nodelist.
      • If the bird is not on the list, then assign result of count to “0”.
      • Otherwise, compute the result associated with bird species.
      • Finally returns the value of result.
    • Define the method “onList” with the argument of “t”.
      • This method is used to check whether target “t” is on the list or not
    • Define the method “find” with the argument of “t”.
      • Assign required variables.
      • Check condition using “while” loop.
    • Define inner node class “ListNode”.
      • Declare required variables.
      • Create parameterized constructor for “ListNode” class.
        • Assign values to required variables.
    • Define main function.
      • Create object “bs” from “BirdSurvey” class.
      • Create object for scanner class.
      • Display statement.
      • Assign “moreValue” to “true”.
      • Check condition using “while” loop.
        • Read bird name from user.
        • If the bird name is “done”, then set “moreValue” to “false”.
        • Otherwise, add the bird name to “bs”.
      • Display the birds report by calling the method “getReport”.

Java Graphics (Bonus 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). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. 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. Regardless of how…
