Example text

Library implementations test for exceptional conditions, cover rarely encountered situations, and submit to extensive testing, so that we can count on them to operate as expected. Such implementations might involve a significant amount of code. For example, we often want implementations for various types of data. For example, Java’s Arrays library includes multiple overloaded implementations of sort(), one for each type of data that you might need to sort. These are bedrock considerations for modular programming in Java, but perhaps a bit overstated in this case.

A Java method can provide only one return value, of the type declared in the method signature. Control goes back to the calling program as soon as the first return statement in a static method is reached. You can put return statements wherever you need them. Even though there may be multiple return statements, any static method returns a single value each time it is invoked: the value following the first return statement encountered. ■ A method can have side effects. A method may use the keyword void as its return type, to indicate that it has no return value.

Each method is described by a line in the API that specifies the information you need to know in order to use the method. The Math library also defines the precise constant values PI (for ␲) and E (for e), so that you can use those names to refer to those constants in your programs. log() implements the natural logarithm function). Java libraries. Extensive online descriptions of thousands of libraries are part of every Java release, but we excerpt just a few methods that we use in the book, in order to clearly delineate our programming model.
