This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
I'm trying to avoid a ridiculous number of 'if's, and the only way I can think of to do so is to build the variable names of constants that are defined elsewhere in the API. Can anyone help? Thanks, g.
and you're using reflection just to reduce the amout of code you have to write Um, have you tried profiling the amount of time to do each? In JDK1.2, method invokation using reflection took 200x longer than calling the method directly. And thats when you cache methods rather than looking them up each time. It apparently got better in JDK1.3 and is now more like 20x as long, but is this really what you want when a second solution might be to format the code differently?
We might be able to help more if you post an example of the code you are trying to streamline. Without, it is difficult to make intellegent suggestions - would a case statement be appropriate? static final constants can often be used to provide mappings to more complex combinations circumventing the limitation of int / char cases.
