   Bufferpoolmxbean, buffer pool management interface, can manage and monitor buffer pool, direct or mapped two kinds of buffer pool.
   Classloadingmxbean, class loading management interface, can manage and monitor the Java Virtual machine class loading system.
   Compilationmxbean, compile the management interface, can manage and monitor the Java Virtual machine's compiling system.
   Garbagecollectormxbean, the garbage Collection management interface, allows you to manage and monitor garbage collection for Java virtual machines.
   Memorymanagermxbean, Memory/memory pool basic information management interface to manage and monitor basic information for the Java Virtual machine memory/memory pool.
   Memorymxbean, Memory information management interface, can manage and monitor the memory information of Java Virtual machine.
   Memorypoolmxbean, the Memory pool management interface, can manage and monitor the use of the Java Virtual machine memory pool.
   Operatingsystemmxbean, an operating system management interface that manages and monitors information about the operating system that a Java virtual machine is running.
   Platformloggingmxbean, the Log management interface, allows you to manage and monitor the logs of Java virtual machines.
   Runtimemxbean, the runtime System Management interface, allows you to manage and monitor the operation of your Java virtual machine.
   Threadmxbean, a thread management interface that can manage and monitor Java Virtual machine threads.

4. Management Plant
   Managementfactory,mxbean's factory class, Mxbean is managed through the factory model, where it obtains the corresponding Mxbean.

6. Information Body
   Lockinfo, Monitorinfo, lock information class, Lockinfo can be any Java lock (including simple Java locks and locks used in Java.util.concurrent packages: Abstractownablesynchronizer and condition implementation classes/subclasses), whereas Monitorinfo is the lock represented by a simple Java object.
   Memorynotificationinfo, the information class for memory notifications.
   Memoryusage, a memory snapshot of the information class, can be obtained through the Memorymxbean, Memorypoolmxbean memory management interface to the memory snapshot information.
   Threadinfo, the thread's information class, can get information to the thread through the Threadmxbean thread management interface.
