| Abstract | In the discussion about the usefulness of static or dynamic type systems there is often the statement that static type systems improve the documentation of software. In the meantime there exists even some empirical evidence for this statement. One of the possible explanations for this positive influence is that the static type system of programming languages such as Java require developers to write down the type names, i.e. lexical representations which potentially help developers. Because of that there is a plausible hypothesis that the main benefit comes from the type names and not from the static type checks that are based on these names. In order to argue for or against static type systems it is desirable to check this plausible hypothesis in an experimental way. This paper describes an experiment with 20 participants that has been performed in order to check whether developers using an unknown API already benefit (in terms of development time) from the pure syntactical representation of type names without static type checking. The result of the study is that developers do benefit from the type names in an API's source code. But already a single wrong type name has a measurable significant negative impact on the development time in comparison to APIs without type names. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
