In the case of Java, having objects as the sole abstraction mechanism also introduces a considerable or even prohibitive cost, especially when dealing with small objects over primitive types. Consequently, Java library implementations frequently avoid abstraction and are not type safe in practice. Many...
If operators cannot be overloaded (like in Java), the expression of arithmetic and set-based constraint is heavier. See Figure 13.9 for a Java fragment setting up the queens problem in the Choco solver. Sign in to download full-size image Figure 13.9. The n–queens problem in Choco. ...
Data abstraction is a powerful technique to overcome state explosion in model checking. For CSPZ (a formal integration of the well-known specification languages CSP and Z), current approaches can mechanically abstract infinite domains (types) as long as
We show how to apply counter ab- straction to real-world concurrent programs to factor out redundancy due to thread replication. The traditional global state representation as a vector of local states is replaced by a vector of thread counters, one per local state. In practice, straightforward ...
In practice, there are enough exceptions to this naming rule that the words “memory” and “storage” have become almost interchangeable. 2.1.1.3 Memory Names and Addresses Physical implementations of memory devices nearly always name a memory cell by the geometric coordinates of its physical ...
We develop a fully abstract trace-based semantics for sets of classes in object-oriented languages, in particular for Java-like sealed packages. Our approach enhances a standard operational semantics such that the change of control between the package and the client context is made explicit in term...
Internationally, coding is increasingly introduced into primary and junior high schools (children generally aged between 5 and 15) on a compulsory basis, though not all stakeholders support this ‘initiative’. In response to the public reception, discus
We have implemented the analysis for inferring numeric properties in Java programs. The experimental results show a tangible precision enhancement compared with classical approaches while preserving a high scalability.Zhoulai FuEuropean Joint Conferences on Theory and Practice of Software...

However, although embodiments of the invention may achieve advantages over other possible solutions and/or over the prior art, whether or not a ...
