Expert Solution & Answer
Chapter 3, Problem 19E
Explanation of Solution
Output for the given program using static scoping:
- In a static scoping, a variable can achieve its top level environment when it is said to be in static scope.
- Static binding makes programmer can figure out the scope of just by seeing at the code...
Explanation of Solution
Output for the given program using dynamic scoping with deep binding:
- The dynamic scoping is the global identifier refers to the identifier related to the most recent environment.
- There is always a run time call static is used to refer the variable in dynamic binding.
- It makes programmer to predict the possible contexts.
- The deep binding is performed at the time of a procedure is passed as an argument.
- The choice is made when the reference is first created.
- The referencing environment is bundled with the subroutine as a closure and passed as an argument for deep binding.
- The implementation is easy in deep binding...
Explanation of Solution
Output for the given program using dynamic scoping with shallow binding:
- The dynamic scoping is the global identifier refers to the identifier related to the most recent environment.
- There is always a run time call static is used to refer the variable in dynamic binding.
- It makes programmer to predict the possible contexts.
- In the shallow binding, the choice is made when the reference is finally used.
- The implementation of shallow binding obvious look for the last activated binding for the name in the stack...

Java Graphics

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…

You must have a main function and a max function. The function int main() will declare an array with the values {12, 100, 10, 1000, 20, 5}. This array will be passed to the max function. The function int max() will perform the necessary operations to find the largest element of the array. After max () is finished, have main () print the largest value and its index in the array.
