We have deliberately avoided file I/O. For Java, it is a multilayered and complex
topic—and with version 1.4 of Java, there is a whole new set of additional
classes (
java.nio.*
) to consider. We refer you instead to Chapter 11 of Eckel's
Thinking in Java
.
There are also a few Java keywords that we have not yet discussed, notably
synchronize
.
Even if you know all the Java syntax, it may still take a while to get familiar
with the way that syntax is typically put to use. Experience and reading other
people's Java code will be your best teachers—but don't assume that a particular
approach is good just because someone else uses it; much new code has been
written in the last several years as people have learned Java. Be sure it's a style
worth imitating, and if you find a better way to do it, use it.
