Explanation of Solution
Lexical analysis and syntax analysis:
Syntax analyzer phase in compilation process is the step in which the “tokens” in the programs are identified and recognize whether they are specified in a valid way. In simple words, tokens are the keywords, identifiers and operators in a
- Lexical analysis: It does the analysis of small language constructs like names and numeric literals.
- Syntax analysis: It does the analysis of large constructs like expressions and program units.
The following three reasons explain why lexical analysis is a separate part from the syntax analyzing process.
Simplicity:
The process of lexical analysis needs relatively less complex techniques than syntax analysis. So, separating low-level details of lexical analysis from syntax analysis make the process of lexical analysis simple, small and clean...

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?

Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list.
