course correct. More importantly, find the bottleneck code that affects the program performance. To find these bottleneck codes, we generally use auxiliary tools such as Jprobe, optimizit, vtune, and some analysis tools such as towerj performance. These auxiliary tools track the time consumed by each function or method in the application to improve the program performance.

1. Square SWT is better than swingThe reputation of Java is obviously very different from what it has achieved in desktop applications (GUI programs). So far, it is rare to see very successful Java Desktop programs. Although there are large software such as JBuilder, netbean, and Jprobe, this still cannot prove that the Java GUI program is successful: their appearance is always incompatible with other software on the same operating system platform. Th

program is deadlocked. Of course, most deadlocks are not so obvious. You need to carefully analyze the code to see that this is especially true for large multi-threaded programs. Good thread analysis tools, such as Jprobe threadalyzer, can analyze deadlocks and point out the problematic code location. Implicit deadlock Implicit deadlock is caused by nonstandard programming methods, but it may not occur during each test. For this reason, some recessiv

leaks. Currently, we usually use some tools to check the memory leakage of Java programs. There are already several professional Java memory leak check tools on the market. Their basic working principles are similar. They are all through monitoring the application, release, and other actions of all objects when Java programs are running, collects, analyzes, and visualizes all memory management information. Based on this information, developers will determine whether the program has a memory lea

, and other actions of all objects when Java programs are running, collects, analyzes, and visualizes all memory management information. Based on this information, developers will determine whether the program has a memory leakage problem. These tools include optimizeit profiler, Jprobe Profiler, jinsight, and purify of rational. Note:An image (reflector) is a program's ability to analyze itself. The Java. Lang. Reflect package provides the ability to

is high, it is likely that inefficient code is causing it. In this case, you should use the Profiling tools to locate bottlenecks in the code for performance. The available tools are:JVISUALVM,Eclipse TPTP , or JProbe. Tuning methodIt is recommended that you use the following methods to tune your program.First, check that performance tuning is necessary. Measuring performance is not a simple job, and you cannot guarantee that you will get a satisfact

to statistical, analysis, visualization. The developer will use this information to determine if the program has a memory leak problem. These tools include Optimizeit Profiler,jprobe profiler,jinsight, Rational company Purify, etc.1detecting the presence of memory leaksHere we will briefly describe the process in which we use the Optimizeit check. Usually, after knowing that a memory leak occurs, the first step is to figure out what data was leaking

and release of objects, as well as multithreaded design and running behavior. Helping you understand the dimension selection of your program at run time is the heavy work of the Code Analyzer. In this article, I've considered three commercial Java parsers and judged which parsers are more likely to meet your needs: · Borland's Optimizeit Suite · Quest Software's Jprobe Suite · Ej-technologies's Jprofiler Analyzer principle It's not surprising t

There are several good code analyzers, such as: Wily Introscope, Jprobe, Optimizelt.EJB ContainerThe most expensive operations in the EJB container are, of course, database calls-loading and storing entity beans.
