Java developers

I am currently through the web materials for a U.C. Berkeley Computer Science class (61B, Data Structures).

One of the solutions for a permutations problem is here. (The problem description is here.)

I can't get the problem solution to run, and I'm wondering if anyone has any ideas. I copied the code solution verbatim into Eclipse. Here are the compile-time errors I get:
-Procedure cannot be resolved to a type (x 7)
-printer cannot be resolved (x 2)

When I try to run it, I get the message: "printer cannot be resolved."

I was wondering if anyone else could get the permutations solution to run, and, if so, how you got it to work (I'm pretty new to Java; it may be very obvious.) Thanks for any help!

I was trying to learn to make use of Spring Framework! to develop a simple web-app so I did a lot of 'googling'. I found information to the tune of thousands of links, huge manuals, e-books etc which are quite cumbersome to follow. (I am a newbie when it comes to Spring!).

( Can you help is this manner?Collapse )
