The importance and benefits of a consistent coding style are well known. This document describes a set of coding standards and recommendations for programs written in the Java language. It is intended for all Java software developers. It contains no material proprietary to Sun, and may be freely

Software development and maintenance are costly endeavors. The cost can be reduced if more software defects are detected earlier in the development cycle. This paper introduces the Extended Static Checker for Java (ESC/Java), an experimental compile-time program checker that finds common

program source code. Bandera takes as input Java source code and generates a program model in the input language of one of several existing verification tools; Bandera also maps verifier outputs back to the original source code. We discuss the major components of Bandera and give an overview of how it can

Abstract JML is a behavioral interface specification language tailored to Java(TM). Besides pre-and postconditions, it also allows assertions to be intermixed with Java code; these aid verification and debugging. JML is designed to be used by working software engineers; to do this it follows

associations in Java, paying special attention to multiplicity, navigability and visibility. Our analysis has encountered some paradoxes in the specification of visibility for bidirectional associations. These principles have been used to write a series of code patterns that we use in combination with a tool

readable, efficient and compact executable code from the UML statechart diagram in an object-oriented (OO) language like Java using design patterns. By representing states as objects, we extend the state design pattern to implement the hierarchical states using the concept of object composition

Abstract. Automated refactorings as implemented in modern IDEs for Java usually make no special provisions for concurrent code. Thus, refactored programs may exhibit unexpected new concurrent behaviors. We analyze the types of such behavioral changes caused by current refactoring engines

The Æ�-calculus, a new calculus based on the �-calculus, is a model for mobile distributed computation. The Æ�-calculus can be used to specify applications, in order to reason about their security and correctness properties. The Æ � primitives have been been implemented as a Java API

Many software systems are subject to continual revisions and expansions as new requirements are discovered, bugs are found, or migrations to new technologies need to take place in order to improve software quality. Many program evolution tasks involve the manipulation of source code in order
