Taming Java for the Classroom
standard Java libraries depends on using immutable data For example, only immutable objects can safely be used as keys in the HashMap and HashTable classes in java util The String class in java lang is immutable for this reason In our experience as software developers, programming with immutable data confers so many advantages that we
A Java implemented key collision attack on the Data
chosen was a Hashtable Java imposes a limit on the number of entries a Hashtable can have so various storage schemes were tested and refined until the following approach was adopted, 1 The (ciphertext,key) pairs were stored in 214 dif-ferent Hashtables 2 During pair generation a number of Hashtables were
Implementation and Use of Data Structures in Java Programs
ing a tool to statically analyze Java libraries and applications Our DSFinder tool reports 1) the number of likely and possible data structure implementations in a program and 2) characteristics of the program’s uses of data structures We applied our tool to 62 open-source Java programs and manually classified possible data struc-tures

MOBILE APPLICATION DEVELOPMENT
Register-based Java virtual machine Runs dex files Similar to a JAR Used a cross compiler tool ‘dx’ Optimized for multiple instances Why not Java ME? Not fully open source Still under control of Sun Micro Veto on any proposed changes
Towards a Green Ranking for Programming Languages
of Java and Haskell data structures [16, 22, 25], analyzing how differ-ent programming coding practices influence energy consumption [28], studying the impact of testing techniques in software energy consumption [14], etc An interesting question that frequently arises in the area of software energy efficiency is whethera faster program is also an
Multicore Acceleration of Priority-Based Schedulers for
an open-source framework that allows selection and comparison of a wide range of interleaving exploration policies for bug detection proposed by prior work Our experience with NeedlePoint indicates that priority-based probabilistic concurrency testing (the PCT algorithm) finds bugs quickly, but it runs only one thread at a time, which
Finding Bugs Efficiently with a SAT Solver
from the Java Collections Framework We also checked for violations of Java’s equality contract in a variety of open-source programs, and found several bugs Categories and Subject Descriptors D 2 4 [Software/Program Veriflcation]: Model Check-ing; F 3 1 [Logics And Meanings of Programs]: Speci-fying and Verifying and Reasoning about Programs
Identifying Static Analysis Techniques for Finding Non-fix
open source projects (Eclipse, Lucene, and Columba) Among to-tal 2146 hunks we found 179 non-fix hunks We classified these non-fix hunks into 11 patterns For all patterns we enumerate en-abling static analysis techniques Categories and Subject Descriptors D2 7[SoftwareEngineering]: Distribution,Maintenance, andEn-
Relational Presentations Using Semantic Closeness Spatial
