java debugging practice

Debugging can help identify and resolve application flaws, in this article, the author will use the common development tools eclipse to debug Java applications. But the debugging methods described here are basically generic and apply to the NetBeans IDE, and we focus on the runtime. Before we begin, we recommend that you take a look at the Eclipse shortcuts arti

Java remote debugging is implemented using the JDWP Protocol. To perform remote debugging, you must add a parameter that supports the JDWP protocol before starting the java program:-Xdebug-Xrunjdwp: transportdt_socket, address8787, servery, suspendn if JDK5 is later, you can use another parameter method:-agentlib: jdwp

In order to prepare for debugging, you need to set a breakpoint in the code first so that the debugger pauses execution allowing you to debug, otherwise the program will execute from the beginning to the end, and you will not have the opportunity to debug.1. Conditional breakpointBreakpoints everyone is familiar with, in the Eclipse Java editing area of the wardrobe double-click to get a breakpoint, the cod

Need to support polling, timed locks. A lock is required for an interruptible lock fetch operation. You want to use a lock in a non-block structure. Learn about an explicit lock that supports more advanced operations. Java 5.0 New Reentrantlock is not an alternative to built-in locking, but an optional advanced feature when the built-in locking mechanism does not apply. 13.1 Lock and Reentrantlock The Reentrantlock implements the lock interface, provi
