Java Pitfalls

Time-Saving Solutions and Workarounds to Improve Programs

Michael C. Daconta, Eric Monk

Résumé

Proven workarounds for common Java™ programming problems

This book was designed to save Java programmers from the backbreaking chore of digging out from problems caused by Java's inherent flaws. Java programming guru Michael Daconta provides proven solutions to 50 difficult problems commonly encountered by Java programmers. He provides workarounds for problems caused by shortcomings in both the Java language itself and in its APIs and utilities, including java.util, java.io, java.awt, and javax.swing. He also explains how to solve common performance-limiting problems that can beset Java applications—an area of critical concern for programmers who develop mission-critical enterprise applications.
