This paper describes one of the processing systems for the quantum programming language NDQJava. Its main feature lies that the classical parts of NDQJava programs are processed by the Java processing system, so this effort emphasizes on the processing of program's quantum parts. This processing system follows the compilation-interpretation approach, and it includes lexical analyzer, syntactic analyzer, code transformer, quantum assembler and quantum interpreter. By the end of this paper, some examples are given. The system was implemented by simulation in June 2006 on the classical computer.
