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.

/**
 * A set of attributes which control a print job.
 * <p>
 * Instances of this class control the number of copies, default selection,
 * destination, print dialog, file and printer names, page ranges, multiple
 * document handling (including collation), and multi-page imposition (such
 * as duplex) of every print job which uses the instance. Attribute names are
 * compliant with the Internet Printing Protocol (IPP) 1.1 where possible.
 * Attribute values are partially compliant where possible.
 * <p>
 * To use a method which takes an inner class type, pass a reference to
 * one of the constant fields of the inner class. Client code cannot create
 * new instances of the inner class types because none of those classes
 * has a public constructor. For example, to set the print dialog type to
 * the cross-platform, pure Java print dialog, use the following code:
 * <pre>
 * import java.awt.JobAttributes;
 *
 * public class PureJavaPrintDialogExample {
 *     public void setPureJavaPrintDialog(JobAttributes jobAttributes) {
 *         jobAttributes.setDialog(JobAttributes.DialogType.COMMON);
 *     }
 * }
 * </pre>
 * <p>
 * Every IPP attribute which supports an <i>attributeName</i>-default value
 * has a corresponding <code>set<i>attributeName</i>ToDefault</code> method.
 * Default value fields are not provided.
