It provides an intuitive UI for viewing system performance, memory usage, potential memory leaks, and thread profiling. It is a favorable choice for many developers. JProfiler is a leading Java profiler in the market. In this section, we will discuss some leading Java profilers such as JProfiler, YourKit, Java VisualVM, and the Netbeans Profiler. There are several Java profilers available. The profilers help us to know the status of the JVM execution at the byte code level. For an optimized application, writing code that just runs is not enough we also need to know its internal performance, such as memory allocation, the implication of concurrent execution, areas where should be improvements, etc. Sometimes we need to know the internal performance of the application. They monitor JVM execution of the byte code and provides the details of the garbage collection, heap memory usage, exceptions, class loading, etc.

Java profilers are the finest tools for understanding the behavior and troubleshooting the performance issues of the Java application.
