The Java Media Framework (JMF) provides a rich set of functionality for building multimedia applications. Using the JMF to build simple multimedia applications is trivial; however, using the JMF to build more complex, interactive multimedia presentations is a much more difficult task. With the recently introduced integration of Tcl and Java, the Tcl language can now be extended to provide a scr...

This paper describes our progress in designing and developing a Java constraint programming class library called JSolver2. JSolver extends the object-oriented programming paradigm of Java with constraint-based declarative programming. Other constraint-based Java tools act as pre-processors to Java. JSolver, on the other hand, is implemented as a set of pure Java classes and allows direct develo...

This paper presents a compiler that translates Scheme code into the Java language. The programming language Scheme is known to be highly expressive and safe. By translating Scheme into Java, one can benefit from such features of Scheme as well as the portability of Java. Our compiler implements dynamic type checking in Scheme via down-casting in Java by mapping each Scheme value to a Java Objec...

In this article, lessons learned from the design of a Java interface to digital cameras are described. The interface allows programmers to interact with a FireWire digital camera directly from within their Java programs. Two types of applications were developed. The first uses the Java 2D API directly to display the information on screen. Java networking is used to transmit the images over a ne...

Providing Java applications with access to low-level system resources, including fast network and I/O interfaces, requires functionality not provided by the Java Virtual Machine instruction set. Currently, Java applications obtain this functionality by executing code written in a lower-level language, such as C, through a native method interface. However, the overhead of this interface can be v...

Java is an object oriented programming language. But mainly because of the costs it’s not widely used on embedded systems. Typical Java virtual machines require larger systems. This work aims for integration of Java on inexpensive 8-bit microcontrollers. This makes Java possible in the world of measurement, control and automation and allows the combination of control, user interaction and commu...

As a first step to combine the two programming paradigms – objectoriented programming and logic programming – we have introduced a generic default mapping for JAVA objects and PROLOG terms. This mapping can be used without any modification to the JAVA classes that stand behind the objects. We also can generate automatically JAVA classes from predicates in PROLOG that map to each other. Apart fr...

he Java programming language promises portable, secure execution of applications. Early Java implementations relied on interpretation, leading to poor performance compared to compiled programs. Compiling Java programs to the native machine instructions provides much higher performance. Because traditional compilation would defeat Java's portability and security, another approach is necessary. T...

java is an object-oriented program that has abundant open-source libraries for application development and 3d model rendering. spatial database is the database that can efficiently store and manage geographic information data though various spatial data management techniques. this paper explores the rationale of coupling java with spatial database to develop an effective platform for future bui...

We explore advances in Java Virtual Machine (JVM) technology along with new high performance I/O libraries in Java 1.4, and find that Java is increasingly an attractive platform for scientific clusterbased message passing codes. We report that these new technologies allow a pure Java implementation of a cluster communication library that performs competitively with standard C-based MPI implemen...
