JRE 8 rt.jar - java.* 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.
