Examples of RuntimeMXBean

java.lang.management.RuntimeMXBean
The management interface for the runtime system of the Java virtual machine.
A Java virtual machine has a single instance of the implementation class of this interface. This instance implementing this interface is an MXBean that can be obtained by calling the {@link ManagementFactory#getRuntimeMXBean} method orfrom the {@link ManagementFactory#getPlatformMBeanServer platform MBeanServer} method.
The ObjectName for uniquely identifying the MXBean for the runtime system within an MBeanServer is:
{@link ManagementFactory#RUNTIME_MXBEAN_NAME java.lang:type=Runtime}

This interface defines several convenient methods for accessing system properties about the Java virtual machine. @see JMX Specification. @see Ways to Access MXBeans @author Mandy Chung @version 1.14, 11/17/05 @since 1.5
