When trying to learn a new programming language like Java you will often say to yourself "Gee, I know how to do that in Pascal", or whatever language you are currently fluent in, "but I wish I knew how to do that in Java". This book is an answer to that wish. If you know how to accomplish a task in knows C, Fortran, Cobol, Pascal or Visual Basic you can look that construct up in the book, and study the solution until you understand the way it works; then, look to the right to find the equivalent construct in Java. By comparing the two and studying any notes that may be included, you should be able to make any changes necessary to adapt the construct to your particular needs.
