Searching and reusing online code has become a common practice in software development. Two important characteristics of online code have not been carefully considered in current tool support. First, many pieces of online code are largely similar but subtly different. Second, several pieces of code may form complex relations through their differences. These two characteristics make it difficult to properly rank online code to a search query and reduce the efficiency of examining search results. In this paper, we present an exploratory online code search approach that explicitly takes into account the above two characteristics of online code. Given a list of methods returned for a search query, our approach uses clone detection and code differencing techniques to analyze both commonalities and differences among the methods in the search results. It then produces an exploration graph that visualizes the method differences and the relationships of methods through their differences. The exploration graph allows developers to explore search results in a structured view of different method groups present in the search results, and turns implicit code differences into visual cues to help developers navigate the search results. We implement our approach in a web-based tool called CodeNuance. We conduct experiments to evaluate the effectiveness of our CodeNuance tool for search results examination, compared with ranked-list and code-clustering based search results examination. We also compare the performance and user behavior differences in using our tool and other exploratory code search tools.
While the classical builder pattern in java is proven to simplify object instantiation it is known to have some inherent imperfections that leave room for improper use and open for run-Time failures. In this paper we ...

Boarding house are temporary homes that are most in demand by students or upper level students. However, to get the appropriate boarding house is not easy because of the difficulty of obtaining boarding house information and also many boarding house criteria that must be considered such as rental rates, room area and boarding house facilities etc. Multi criteria decision support system using the Topsis method can facilitate students in finding boarding house. Users can input the boarding house criteria to be searched such as rental rates, room area and boarding house facilities, then after that a mathematical calculation will be performed on each boarding house using the Topsis method. Resulting in board recommendations that match what the user is looking for. The system is made using java for Android-based programming. The test is performed using the confusion matrix method to measure the accuracy of the costing recommendations produced by the system, resulting in 83% accuracy and 17% of recommendation errors.
It is challenging to develop a cross-platform application, that is, an application that runs on multiple platforms. It requires not only code reuse but also an individual building or compilation for each platform, pos...
