-Xlint:unchecked, sockets, ports

Today we reviewed code from this repo:

• https://github.com/UCSB-CS56-pconrad/hfj-chap15

We discussed the -Xlint:unchecked issue

• See also: https://ucsb-cs56-pconrad.github.io/topics/java_unchecked/

We mentioned briefly how you can compile and run the code in the repo using plain old java commands.

To find classes that have a main method, use the grep command with -r (recursive) flag on the src directory:

grep -r 'public static void main' src

Then:

ant compile
java -cp build chap15.NameOfClassGoesHere

We discussed that the chap15 refers to the “package” in which the code is located.

We also started a discussion of the port number issue, as discussed here:
