The Language Extensions Scientific Computation, XSC in short, were introduced in order to provide an appropriate environment programming to support scientific and interval computing. This class of languages provide important tools to development of numerical software. For example, provide an automatic control of numerical error, libraries with the main mathematical routines, dynamic arrays, data type not existent in traditional programming languages, such as complex numbers, real interval, etc. beyond of several other characteristic.
The present work has as main goal to present the basic characteristic of our proposal of XSC library for JAVA programming language.
