Packages, Utilities, and Error Handling

"To err is human, but to really foul things up requires a computer."
Farmers' Almanac, 1978   

Introduction

In this chapter you will learn about the important packages that are included in Java to assist you, as well as how to create your own, reusable packages. We will delve into the way you handle errors in Java, and we will also take a look at assertions, which are new to the 1.4 release of the Java SDK.
