Learning to create well-designed and robust Java programs requires, besides a good understanding of the language, a significant amount of practice. In this paper we present the JavaFest, a collaborative learning technique for teaching Java to beginning ...

In many fields of Computer Engineering education it is crucial that students gain both conceptual understanding and practical skills. To this end, an effective teaching approach relies on a blended-learning strategy that combines face-to-face lessons ...

Courses on software architecture and software engineering need to explain the role of non-functional properties in software design, and they often use student projects to highlight their interrelations. Despite its critical importance in software ...

We present a framework for command processing in Java/Swing programs based on the model-view-controller (MVC) pattern. In addition to standard approaches our framework supports (1) centralized exception handling, (2) premature command termination, (3) ...

There is a growing demand to apply multi-robot systems to address many current problems ranging from search and rescue to distributed surveillance to coordination of small satellites in space. Solving these problems effectively requires that teams of ...

Object-to-relational maps are nowadays routinely utilized in providing a persistency mechanism for object-oriented programs. We present how an object-to-relational mapper, such as Hibernate, provides transparent persistency to object-oriented programs. ...

The move toward pure managed-code environments is held back by the vast amount of legacy software available only as statically compiled binaries for some legacy instruction set architecture (ISA). Catering to this legacy software requires all sorts of ...

The development of a complete Java Virtual Machine (JVM) implementation is a tedious process which involves knowledge in different areas: garbage collection, just in time compilation, interpretation, file parsing, data structures, etc. The result is ...

As a safety measure, the Java programming language requires bounds checking of array accesses. This usually translates to dynamic checks each time an array element is accessed. Static analysis can help eliminate some of those checks by proving them to ...

In many scenarios a field holds a value that is constant beyond a certain point in the execution of the program. However, Java only allows it to be marked as being final in relation to the control-flow of the program. We present a language extension ...

In several Java VMs, strings consist of two separate objects: metadata like the string length are stored in the actual string object, while the string characters are stored in a character array. This separation causes an unnecessary overhead. Each ...

Embedded systems are inherently limited in terms of local storage capacity. This limitation conflicts with the demands of modern virtual machine platforms, which require large amounts of library code to be present on each client device. These ...

Though often criticized for its inherent synchronization overhead and coupling, the remote method invocation (RMI) paradigm remains one of the most popular abstractions for building distributed applications. Many authors have suggested ways to overcome ...

When Java developers need to improve the performance of their applications, they usually use one of the many existing profilers for Java. These profilers generally capture a profile that represents the execution time spent in each method. The developer ...

Traits are pure behavior components introduced in the Smalltalk community in order to integrate the traditional class inheritance with a composition mechanism: a class is composed by traits and inherits from superclasses. This offers the advantage of ...

Aspect-oriented programming (AOP) has been successfully applied to application code thanks to techniques such as Java bytecode instrumentation. Unfortunately, with current technology, such as AspectJ, aspects cannot be woven into standard Java class ...

Class inheritance and method overriding, as provided by standard class-based languages, are not flexible enough to represent the dynamic behavior of objects; with this respect, object composition and delegation are often advocated as a more flexible ...

In the past we analyzed typeless Java programs. One of our results was, that there may be different correct typings for one method. This means that the principal types of such methods are intersection types. We presented a type-inference algorithm. For ...

Projects like jMock and Hibernate Criteria Query introduced embedded DSLs into Java. We describe two case studies in which we develop embedded typesafe DSLs for building SQL queries and engineering Java bytecode. We proceed to extract several patterns ...
