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.
