中文摘要：

针对软件项目开发中维护阶段的成本和工作量难以估计的问题，提出一种基于Java程序的功能点度量方法，并介绍从目标程序中抽取数据功能点以及事务功能点的计算规则，同时以Java源代码为例说明具体的度量过程。实验结果表明，该方法是有效可行的。

英文摘要：

Aiming at the problems that it is difficult to estimate the cost and workload during the maintenance period of software development, a function point measurement method based on Java program is presented. The counting rules for extracting data and transactional function points from object program are also introduced. An example of Java source code is given to explain the detail of the measurement process. Experimental results show this method is effective and feasible.
