1.Eclipse, IntelliJ ideaEclipse is the Swiss Army knife in the IDE, with a large number of custom interfaces and countless plugins. It is ubiquitous, and the Eclipse plugin is available in all other tools that this article will recommend.Eclipse's workflow can be divided into three areas: Workbench, Workspace, and perspective. Workbench as a starting point to the IDE. Workspaces combine project, file, and configuration settings in a separate directory

What is BEAM? A statement about the abbreviation BEAM In the purpose of brevity, this article uses the abbreviation-beam of the tool name, which is simply the acronym for the tool's "Checking Tool for Bugs Errors and mistakes", rather than the name of the tool. IBM Checking Tool for Bugs Errors and mistakes (with its initials BEAM later in this article) is a static analysis tool developed by IBM that can be used to analyze and find some of the less-easily discovered in C, C + +, and

During application maintenance for the customer, I noticed some performance problems under high load conditions. Theoretically, increasing the load on the application will reduce the performance, but I think the performance drop rate is much higher than the load increase. At the same time, I also found that, performance can be improved by changing the logic of the application. To learn more about this, we need to perform some performance analysis. At this time, we naturally need to use some perf

AppFuse is an open source project and application that uses open source tools built on the Java platform to help us develop WEB applications quickly and efficiently. I originally developed it to reduce the unnecessary time it takes to build a new WEB application for a customer. At the core, AppFuse is a skeleton of the project, similar to what the IDE creates when you create a new Web project through a wiza

"Profiler" tab of the Application tab. With this Profiler, you can analyze memory usage and CPU performance for local applications.Note: To perform profiling on an application running on JDK 6, you need to turn off class sharing for that application, or the application may crash. To turn off class sharing, start the application with the-xshare:off parameter. Start the local Java application. (Use the-xshar
