Program Plan Intro

Command line arguments:

  • When the user run the program at that time the information is passed to the program is called as command line argument.
  • The passed information is stored as a string array in the main method. After that, the user can use the command line arguments in their program.
  • The information is passed as the “Strings”.
  • There is no restriction on the number of java command line arguments. The user can specify any number of arguments.
  • They are captured into the “String args” of the main method.

Example:

If the user starts a program with the command line as

java ProgramClass –d file1.txt

  • Now the program receives two command line arguments which means “-d” and “file1.txt”.
  • This is totally depending on the program what to do with these strings.
  • It is customary to interpret strings starting with a “hyphen (-)” as program options.

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?
