  • Hunting Memory Leaks in Java (Publication)
    Inexperienced programmers often think that Java's automatic garbage collection frees them from the burden of memory management. This is a common misperception: while the garbage collector does its best, it's entirely possible for even the best programmer to fall prey to crippling memory leaks. In this post, I'll explain how and why memory leaks occur in Java and outline an approach for detecting such leaks with the help of a visual interface.
