Constructive Foundations for Featherweight Java

Featherweight Java A Minimal Core Calculus for Java and GJ

Several recent studies have introduced lightweight ver sions of Java reduced languages in which complex fea tures like threads and re ection are dropped to enable rigorous arguments about key properties such as type safety We carry this process a step further omitting almost all features of the full language including inter faces and even assignment to obtain a small calculus Featherweight Java...

A Theory of Featherweight Java in Isabelle/HOL

We formalize the type system, small-step operational semantics, and type soundness proof for Featherweight Java [1], a simple object calculus, in Isabelle/HOL [2].

Featherweight Generic Ownership

Object ownership is an approach to controlling aliasing in programming languages. Proposals for adding ownership to programming languages do not directly support type genericity. We present Featherweight Generic Ownership — the first system to unify ownership and type polymorphism. Our type system extends Featherweight Generic Java with locations to support ownership and confinement invariants,...

LazyJ: Seamless Lazy Evaluation in Java

LazyJ is a backward-compatible extension of the Java programming language that allows programmers to seamlessly tap into the power and expressiveness of lazy evaluation. It does so by extending Java’s type system with lazy types. A variable of type lazy T (where T is any Java type) can hold a thunk which when evaluated will yield a value of type T. The existence of coercions between non-lazy an...
