This paper presents an overview of a quantum programming language NDQJava-2.NDQJava-2 is an extension of NDQJava with additional quantum components such as quantum conditional statement, quantum loop statement, quantum subprogram, quantum module, and quantum exception handling mechanism.The added commponents make NDQJava-2 a structured quantum programming language.Experience in writing quantum programs indicates that compared with NDQJava, NDQJava-2 is a more practical, more readable and more suitable (components setting) quantum programming language.

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.
