literals and for string to floating-point conversion methods in the Float and Double
classes.
Serialization
New support handles new enumerated types. The rules for serializing an enum instance differ
from those for serializing an "ordinary" serializable object: the serialized form of an enum
instance consists only of its enum constant name and information identifying its base enum
type. Deserialization behavior differs as well: the class information is used to find the
appropriate enum class, and the Enum.valueOf method is called with that class and the
received constant name to obtain the enum constant to return.
Monitoring and Management Support
A new monitoring and management API for the Java VM  the
java.lang.management package.
●
A new monitoring and management API for the logging facility 
java.util.logging.LoggingMXBean interface.
●
Java Management Extensions (JMX) provides built-in instrumentation that enables you to
monitor and manage it using JMX. You can easily start a JMX agent for monitoring and
managing remote or local Java VMs instrumentation or of any application with JMX
instrumentation. For more information, see Monitoring and Management Using JMX.
●
The SNMP (Simple Network Management Protocol) agent publishes the standard
management information base (MIB) for the Java VM instrumentation as defined by Java
Specification Requirement (JSR) 163. For more information, see SNMP Monitoring and
Management.
●
Java Management Extensions  JMXTM API version 1.2 and the RMI connector of the
JMX Remote API version 1.0 are included in the J2SE 5 release. The JMX API allows
you to instrument libraries and applications for monitoring and management. The RMI
connector allows this instrumentation to be remotely accessible. For more information,
see the JMX documentation.
