Other base libraries, including international support, input/output (I/O), extension mechanism, Beans, Java Management Extensions (JMX), Java Native Interface (JNI), Math, Networking, Override Mechanism, Security, Serialization and Java for XML Processing (XML JAXP).Integration libraries including Interface Definition Language (IDL), Java Database Connectivity (JDBC), Java Naming and Directory Interface (JNDI), Remote Method Invocation (RMI), Remote Method Invocation Over Internet Inter-Orb Protocol (RMI-IIOP) and scripting.User interface toolkits, including Abstract Window Toolkit (AWT), Swing, Java 2D, Accessibility, Image I/O, Print Service, Sound, drag, and drop (DnD) and input methods.Deployment technologies such as deployment, Java plug-in, and Java Web Start.JRE consists of the following components: Other base libraries like Java Management Extensions (JMX), Java Native Interface (JNI) and Java for XML Processing (JAX-WS).Integration libraries like Java Database Connectivity (JDBC) and Java Naming and Directory Interface (JNDI).Toolkits for user interface like Java 2D.Technologies which get used for deployment such as Java Web Start.JRE acts as a layer on the top of the operating system. The JRE loads classes, verify access to memory, and retrieves the system resources. If you wish to run this bytecode on any platform, you require JRE. The source Java code gets compiled and converted to Java bytecode. It is the most common environment available on devices to run java programs. It is a freely available software distribution which has Java Class Library, specific tools, and a stand-alone JVM. Java Run-time Environment (JRE) is the part of the Java Development Kit (JDK).
