I am writing a simple checkers game in Java. When I mouse over the board my processor ramps up to 50% (100% on a core).
I would like to find out what part of my code(assuming its my fault) is executing during this.
I have tried debugging, but step-through debugging doesn't work very well in this case.
Is there any tool that can tell me where my problem lies? I am currently using Eclipse.

Profiling is the process of examining an application to locate memory or performance-related issues. When profiling a Java application, you can monitor the Java Virtual Machine (JVM) and obtain data about application performance, including method timing, object allocation and garbage collection.
JProfiler is a Java profiler tool and is useful for developers/testers as it can be used to analyze performance bottlenecks, memory leaks, CPU loads, and to resolve threading issues. JProfiler works both as a stand-alone application and as a plug-in for the Eclipse software development environment.
To profile them, select the necessary configuration, click the clock icon in the top toolset pane, and select the desired profiling option: Async Profiler or Java Flight Recorder. These were the most useful and powerful features that IntelliJ IDEA offers for profiling Java applications.
This is called "profiling". Your IDE probably comes with one: see Open Source Profilers in Java.

Use a profiler (e.g yourkit )
