Preface

The Multitasking Guide highlights multitasking programming issues in the Sun Java™ Wireless Client software. It describes how to make code safe for the multitasking environment of the Java Wireless Client software. There is a special section about resource management. The Multitasking Guide also describes some multitasking policies implemented in the Java Wireless Client software and discusses possible alternatives.

Note – Sun Microsystems has simplified the naming schemes for the various Java platforms. Java Platform, Enterprise Edition (Java EE) was formerly Java 2 Platform, Enterprise Edition (J2EE™). Java Platform, Standard Edition (Java SE) was formerly Java 2 Platform, Standard Edition (J2SE™), and Java Platform, Micro Edition (Java ME) was formerly Java 2 Platform, Micro Edition (J2ME™).

References in this guide to specific documents, specifications, and products that were released when the old naming scheme was in use retain their original names. General references in this guide to Java platforms use the new, simplified naming scheme.

Before You Read This Guide

Readers using this guide must be familiar with the MIDP 2.1 Specification. The specification is available from http://www.jcp.org/. It is also useful if the reader is familiar with the Java Wireless Client software code.

Sun Microsystems, founded in 1982, was a significant player in the computing industry, best known for its innovative technology solutions and workstations, particularly the Sun-4, which represented a key milestone in the company's history. The Sun-4 architecture, launched in 1987, utilized the SPARC (Scalable Processor Architecture) RISC processor, notable for its high performance and scalability.

One of the primary features of Sun Microsystems' platforms was their ability to efficiently handle multitasking and resource management, making them ideal for enterprise-level applications and development environments. Sun-4 workstations boasted impressive graphics capabilities with the addition of advanced graphical user interfaces, support for color displays, and the SUNVIEW windowing system, which enhanced user experience and productivity.

The Sun-4 systems also supported the SunOS operating system, which was based on UNIX. This operating system was engineered for stability and robustness, offering features like multiuser support, networked environments, and advanced security options. Moreover, SunOS provided seamless integration with various programming languages, including C and C++, facilitating software development that aligned with industry standards.

Another standout characteristic of Sun Microsystems was its commitment to open systems and standards. By providing developers with comprehensive tools and environments, such as the Standardized Application Programming Interface (API) and support for networking protocols, Sun facilitated interoperability among different computing platforms. The emphasis on open architecture also meant that customers could easily upgrade their systems without being locked into proprietary solutions.

Sun Microsystems was also ahead of its time with innovations in network computing. Their workstations were among the first to support network file systems and distributed computing concepts, enabling seamless data sharing across multiple systems. With the introduction of the Network File System (NFS), Sun revolutionized how data was accessed and managed across networks, which played a significant role in the evolving landscape of client-server computing.

In summary, the Sun Microsystems 2 and its successive innovations in workstation technology highlighted the company's forward-thinking approach. By integrating powerful performance with open systems, robust operating systems, and advanced networking capabilities, Sun laid the groundwork for modern computing, influencing various sectors from academia to enterprise solutions. Even after its acquisition by Oracle in 2010, the legacy of Sun Microsystems continues to be felt across the computing industry.
