Recently, the object-oriented programming language Java has been used in many practical systems including enterprise servers, smart phones, and embedded systems, due to its high safety and portability. Thus, a lot of educational institutes have offered Java programming courses to foster Java engineers. In this paper, we propose a Web-based Java Programming Learning Assistant System (JPLAS) usin...

Pizza is a strict superset of Java that incorporates three ideas from the academic community: parametric polymor-phism, higher-order functions, and algebraic data types. Pizza is deened by translation into Java and compiles into the Java Virtual Machine, requirements which strongly constrain the design space. Nonetheless, Pizza ts smoothly to Java, with only a few rough edges.

Toba is a system for generating efficient standalone Java applications. Toba includes a Java-bytecode-to-C compiler, a garbage collector, a threads package, and Java API support. Toba-compiled Java applications execute 1.5–10 times faster than interpreted and Just-In-Time compiled applications.

We outline an object-oriented extension to Camelot, a functional language in the ML family designed for resource aware computation. Camelot is compiled for the Java Virtual Machine, and our extension allows Camelot programs to interact easily with the Java object system, harnessing the power of Java libraries and allowing Java programs to incorporate resource-bounded Camelot code.2

The Java Grande Forum aims to drive improvements to the Java language and its standard libraries in order that Java may be eeciently used for large-scale scientiic applications, particularly on high-performance computers. Random number generators are one of the most commonly used numerical library functions in applications of this kind. For the current random number generator provided within Ja...

Received (received date) Revised (revised date) Communicated by (Name of Editor) ABSTRACT PVM for Java (JPVM) is a parallel programming environment that provides a set of Parallel Virtual Machine (PVM)-like class libraries developed using Java. JPVM inherits the attributes of Java, especially Java support of heterogeneous system. However, it also has the disadvantage of poor performance when co...

This paper reports on the design, implementation and benchmarking of a Java version of the Nas Parallel Benchmarks. We first briefly describe the implementation and the performance pitfalls. We then compare the overall performance of the Fortran MPI (PGI) version with a Java implementation using the ProActive middleware for distribution. All Java experiments were conducted on virtual machines w...

This paper describes a radical approach to aggressively optimize an embedded Java virtual machine interpretation in a portable way. We call this technique Semantically Enriched Code (sEc). The sEc technique can improve the speed of a JVM by orders of magnitude. The sEc technique adapts an embedded Java virtual machine to the demands of a Java application by automatically generating an enhanced ...

The role of Java in high performance computing is discussed with particular reference to the eeorts of the Java Grande Forum to develop Java into the environment of choice for large-scale, resource-hungry applications. The support provided in HPJava for the design of parallel Java programmes is outlined, and its use demonstrated with a data mining application based on a neural network.
