Table of New Features in JDK 1.1

Package Feature JDK 1.1 JDK 1.2 Enhancements

java.text, java.io Internationalization API to handle international languages and scripts. Input Method Framework and minor API changes.

java.applet Audio Sound capabilities from applications. The getAudioClip and newAudioClip methods let you create and use AudioClips from applications.

java.beans JavaBeans^TM Reusable software components that can be manipulated in a GUI. Runtime containment and services protocol, and drag-and-drop support.

---TD> Security Architecture Applets confined to secure environment and digitally signed JAR files. Fine-grain access control for applets and applications.

java.security Cryptography Digital signature and message digest APIs. Policy-oriented architecture, and APIs to support cryptographic services and key management.

java.awt.sql JDBC^TM Standard API to issue and process SQL statements. Result sets that scroll forwards and backwards, batch updates, persistent object storage, character stream support, and full precision java.math.BigDecimal values.

java.rmi Remote Method Invocation
(RMI) Method-based standard API for network communications. Remote object activation, downloadable socket factories, and minor API enhancements.

java.util.jar Java ARchive (JAR) File Format Mechanism to bundle and sign Java program files. Enhanced command-line JAR tool, New API for reading and writing JAR files, ability to reference JAR files at a specified URL.

--- Java Native Interface (JNI) Standard naming and calling convention API for native method invocation. New methods for library and version management, local reference management, weak global references, array operations, string operations, reflection support, and the Invocation API.

java.lang.reflect Reflection API to access information on fields, methods, and constructors of loaded classes. Ability to bypass JDK 1.2 access controls.

Table of New Features in JDK 1.2

Package Feature JDK 1.2

java.util Collections API to group and manipulate objects of different types.

java.awt,
java.awt.color,
java.awt.geom,
java.awt.image,
java.awt.print Java 2D APIs for designing more interesting and user-friendly interfaces, handling color, processing images, addressing multilingual requirements, using stylized text, and printing.

javax.servlet Servlets API for extending server functionality.

java.org.omg.CORBA,
java.org.omg.CosNaming Java IDL API for invoking a transparent remote operation.

javax.naming Java Extension Mechanism API to add extensions to core platform.

java.lang.ref Reference Objects API to create a reference to an object so a program can maintain a reference to that object after it is eligible for garbage collection.
