Thread: Printing from a Method

My last post was kind of buggy, so heres this one. My code will not print method printTrigTables, but it prints the other two declared in main

Any idea of why it's not picking that up?

Does the program finish running, or does it hang? Also, you seem to have a rogue ; floating in limbo.

Yeah I fixed the ; , but it does finish running. It doesn't act as though its picking up the call in main.

The code looks like it should work to me, perhaps try adding System.out.flush() at the end to make sure its not stuck in stdout... Are you running it in an IDE or on the command line?

Im running it in netBeans IDE, flush didn't seem to help, any other ideas? :/

Quick question about your sin, cos, and etc, you're using Math.a[....] which is the arc[....]. Were you intending this? or did you just want Math.cos and etc?

Ill change that atm Act.

Still didn't change any output.

must say I am at a loss. Ill try running it for myself later(when Im at home) if you haven't figured it out by then. You don't need to be declaring all those doubles in main, but that wouldn't effect printl.

Thanks copeg, it worked for some reason if I just deleted it all
