JRE 8 rt.jar - javax.* 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 javax.* package in JRE 1.8.0_191 rt.jar. Java source codes are also provided.

An enumeration class * (which extends class EnumSyntax) provides a group of enumeration values * (objects) that are singleton instances of the enumeration class; for example: * <PRE> * public class Bach extends EnumSyntax { * public static final Bach JOHANN_SEBASTIAN = new Bach(0); * public static final Bach WILHELM_FRIEDEMANN = new Bach(1); * public static final Bach CARL_PHILIP_EMMANUEL = new Bach(2); * public static final Bach JOHANN_CHRISTIAN = new Bach(3); * public static final Bach P_D_Q = new Bach(4); * * private static final String[] stringTable = { * "Johann Sebastian Bach", * "Wilhelm Friedemann Bach", * "Carl Philip Emmanuel Bach", * "Johann Christian Bach", * "P.D.Q. Bach" * }; * * protected String[] getStringTable() { * return stringTable; * } * * private static final Bach[] enumValueTable = { * JOHANN_SEBASTIAN, * WILHELM_FRIEDEMANN, * CARL_PHILIP_EMMANUEL, * JOHANN_CHRISTIAN, * P_D_Q * }; * * protected EnumSyntax[] getEnumValueTable() { * return enumValueTable; * } * } * </PRE> * You can then write code that uses the <CODE>==</CODE> and <CODE>!=</CODE> * operators to test enumeration values; for example: * <PRE> * Bach theComposer; * . . . * if (theComposer == Bach.JOHANN_SEBASTIAN) { * System.out.println ("The greatest composer of all time!"); * } * </PRE> * The <CODE>equals()</CODE> method for an enumeration class just does a test * for identical objects (<CODE>==</CODE>). * <P> * You can convert an enumeration value to a string by calling {@link * #toString() toString()}. The string is obtained from a table * supplied by the enumeration class. * <P> * Under the hood, an enumeration value is just an integer, a different integer * for each enumeration value within an enumeration class. You can get an * enumeration value's integer value by calling {@link #getValue() * getValue()}. An enumeration value's integer value is established * when it is constructed (see {@link #EnumSyntax(int) * EnumSyntax(int)}). Since the constructor is protected, the only * possible enumeration values are the singleton objects declared in the * enumeration class; additional enumeration values cannot be created at run * time. * <P> * You can define a subclass of an enumeration class that extends it with * additional enumeration values. The subclass's enumeration values' integer * values need not be distinct from the superclass's enumeration values' integer * values; the <CODE>==</CODE>, <CODE>!=</CODE>, <CODE>equals()</CODE>, and * <CODE>toString()</CODE> methods will still work properly even if the subclass * uses some of the same integer values as the superclass. However, the * application in which the enumeration class and subclass are used may need to * have distinct integer values in the superclass and subclass. * <P> * * @author David Mendenhall * @author Alan Kaminsky */ public abstract class EnumSyntax implements Serializable, Cloneable { private static final long serialVersionUID = -2739521845085831642L; /** * This enumeration value's integer value. * @serial */ private int value; /** * Construct a new enumeration value with the given integer value. * * @param value Integer value. */ protected EnumSyntax(int value) { this.value = value; } /** * Returns this enumeration value's integer value. * @return the value */ public int getValue() { return value; } /** * Returns a clone of this enumeration value, which to preserve the * semantics of enumeration values is the same object as this enumeration * value. */ public Object clone() { return this; } /** * Returns a hash code value for this enumeration value.
