IntroductionThis article is the second article in the Java Performance Analysis tool series, the first article: Operating system Tools. In this article, you will learn more about Java applications and the JVM itself using built-in Java monitoring tools. There are many built-in tools in the JDK, including: Jcmd

Java performance analysis tools, Part 1: Operating System Tools, java operating systemsIntroduction The premise of performance analysis is that the running status of the application and the running environment of the application are displayed more directly in a visual manner. How can we achieve this visual display? We

Introduction This article first introduces the basic concepts and main technologies of static code analysis, and then introduces four existing mainstream Java static code analysis tools (Checkstyle, findbugs, PMD, jtestIn the end, they are analyzed and compared in terms of functions and features, hoping to help Java software developers understand static code

I have learned 264 for more than three months. I have been studying old books and reading jm86 many times.CodeRecently, we found two major analysis tools: visa and elecard streameye. I can't help but sigh, hate at the same time. To put it simply, the two software: 264 visa Powerful h264 real-time analysis tool that can analyze h264 resources in various scenari

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

It is recently necessary to convert files in PNM format into GIF files in bulk. I have tried the following image conversion tools:Imagebatch: Completely free, but only supports PNG JPEG BMP gif four formatofficeconverter: Online conversion software, supporting the conversion of all image formats, a large number of image processing needs to pay a certain fee, otherwise inefficientpixillion: Support for all formats, the trial version only supports up to 5 files for a set of batch processing, 100 t
