Esterel is a mature reactive language used to specify and implement realtime and time-critical systems. In this article, we investigate its use with Java and describe a Java binding for Esterel. We show that Esterel programs translate and integrate well into Java. The real-time, critical part of the code can be specified with Esterel and verified with a large set of tools, before being turned i...

This paper describes the use of Java for developing a mission critical application in ABB's power generation segment. It presents the rationale for choosing Java, the experience made with both Java itself and diverse tools, how the logistics challenge was approached with Java, and issues to be considered when building multi-tier internet applications. As a conclusion some suggestions are made a...

Java, the Java Virtual Machine, and the Java API have captured the imagination of many programmers in the short time since they have been released. In this paper we examine an aspect of the Java API from a security context. We show that the security model is adequate from the perspective of the implementors of Java but fails to provide the function-ality required by users and programmers in the...

This article looks at the advantages and disadvantages of using Java and Java 3D for games programming. It assumes the reader is familiar with Java, but presents short overviews of gaming, the low-level APIs OpenGL and DirectX, and Java 3D. No programming examples are included here, although links to online code are supplied. 1. Background to Gaming Giving a definition for ‘computer game’ is pr...

In their analysis of the use of Java as a first teaching language, the ACM Java Task Force (JTF) identified a number of issues with the Java language and APIs which caused significant pedagogic problems. The focus of their work, and hence of their characterisation of the issues, was the Java “Standard Edition” (J2SE). This paper contends that the version of Java designed for programming small d...

Java bytecode subroutines are used to compile the Java source language try-finally construct into a succinct combination of special-purpose instructions. However, the space saved by using subroutines, in comparison to simpler compilation strategies, comes at a substantial cost to the complexity of the bytecode veriier and other parts of the Java Virtual Machine. This paper examines the trade-oo...
