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.

 * not instances of {@code Attribute}.  However, an {@code AttributeList}
 * can be made <em>type-safe</em>, which means that an attempt to add
 * an object that is not an {@code Attribute} will produce an {@code
 * IllegalArgumentException}.  An {@code AttributeList} becomes type-safe
 * when the method {@link #asList()} is called on it.</p>

/* We cannot extend ArrayList<Attribute> because our legacy
   add(Attribute) method would then override add(E) in ArrayList<E>,
   and our return value is void whereas ArrayList.add(E)'s is boolean.
   Likewise for set(int,Attribute).  Grrr.  We cannot use covariance
   to override the most important methods and have them return
   Attribute, either, because that would break subclasses that
   override those methods in turn (using the original return type
   of Object).  Finally, we cannot implement Iterable<Attribute>
   so you could write
       for (Attribute a : attributeList)
   because ArrayList<> implements Iterable<> and the same class cannot
   implement two versions of a generic interface.  Instead we provide
   the asList() method so you can write
       for (Attribute a : attributeList.asList())
