AbstractThis paper describes the new Java components of MDSplus. These tools represent the evolution of some MDSplus components (MDSplus Current Developments and Future Directions, this conference) previously written in c, taking advantage from the multiplatform interoperability provided by the Java framework. The use of Java in the development of these tools provided an impressive reduction in the coding and test time. This is mainly due to the large set of ready-to-use components of the Java framework, and to the effective code re-use which can be achieved in the organization of Java applications.
