In this work we present a type graph that models all executable constructs of the Java programming language. Such a model is useful for any graph-based technique that relies on a representation of Java programs as graphs. The model can be regarded as a common representation to which all Java syntax graphs must adhere. We also present the systematic approach that is being taken to generate synta...

Recently, a new generation of mobile phones with support for Java has been taking widespread acceptance by the market, creating a business potential for downloadable Java Games and enterprise applications. However, it is relatively easy to forward Java programs between two Java phones. This opens the door for illegal peer-to-peer forwarding, with the consequent loss of revenues for content prov...

Compared to imperative programming languages like Pascal or Basic, or functional programming languages like ML or Haskell learning Java is hampered by the fact that to get even the simplest running program the learner has to define a public class and a method with a certain signature. We present both a stand-alone and a webbased interpreter which execute Java fragments and relieve the learner f...

Java is seen as an important applications-programming language of the future. However the performance of Java programs on the Java Virtual Machine (JVM) leaves much to be desired. In this report, I describe the implementation and performance of a Java-to-C++ translator for stand-alone Java application programs. My experiments show that it is possible to get between one to two orders of magnitud...

Java is widely applied from the small embedded devices to enterprise systems nowadays due to its object-oriented features and corresponding advantages of security, robustness, and platform independence. Java programs are compiled into Java Bytecodes, which are executed in the Java virtual machine. Among the current hardware or software solutions to the Java virtual machine, the object-oriented ...
