JRE 8 rt.jar - com.* Package Source Code

JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

JAR File Information:

Directory of C:\fyicenter\jdk-1.8.0_191\jre\lib
      63,596,151 rt.jar

Here is the list of Java classes of the com.* package in JRE 1.8.0_191 rt.jar. Java source codes are also provided.

/**
 * Implementation class that uses Java serialization for output streams.
 * This assumes a GIOP version 1.2 message format.
 *
 * This class uses a ByteArrayOutputStream as the underlying buffer. The
 * first 16 bytes are direct writes into the underlying buffer. This allows
 * [GIOPHeader (12 bytes) + requestID (4 bytes)] to be written as bytes.
 * Subsequent write operations on this output stream object uses
 * ObjectOutputStream class to write into the buffer. This allows marshaling
 * complex types and graphs using the ObjectOutputStream implementation.
 *
 * Note, this class assumes a GIOP 1.2 style header. Note, we expect that the
 * first 16 bytes are written only using the write_octet, write_long or
 * write_ulong method calls.
