For some caching I'm thinking of doing for an upcoming project, I've been thinking about Java serialization. Namely, should it be used? Now I've previously written custom serialization and deserialization (Externalizable) for various reasons in years past.

In application frameworks I keep seeing frameworks that allow you to pass in multiple Int values (generally used in place of an enum) into a function. For example: public class Example { public class Values { public static final int ONE = 0x7f020000; public static final int TWO = 0x7f020001; public sta...

The Timer calls run() every 500 milliseconds. However, my whole Swing GUI freezes up when this thread is downloading stuff from the Internet. I want it to run in ...
I have a JTree implementation for directories in the file system. The problem I have is that when a directory is removed or renamed, the tree still shows the directory in it's parent. The parent tree seems not to be updated for any changes once a node has been expanded. The model I have written does not cache (I have commented out what...
I'm working on a project fuzzing a media player. I wrote the file generator in Java and converted the CRC generator from the original compression code written in C. I can write data fine with DataOutputStream, but I can't figure out how to send the data as an unsigned character array in java. In C this is a very straightforward proces...

How to I specify the host URL at runtime, e.g. from a command-line argument? The ge...
