| 摘 要： | 用Java语言定义了一个线程类,并用System类中的静态方法eurrentTimeMillis()计算时间,从而比较了用不同个数的线程求数组元素和的时间.通过实验证明在LimLx、Windows 2000 Advanced Server和Windows XPProfessional系统中,在加数个数一定的条件下,并不是线程数越多,效率越高.而是要用合适的线程数.同时通过分析了在Windows XP Professional中,不同配置的计算机线程个教与加数的关系相似.

| Abstract: | A thread class was defined in the Java language,and the times of determining the summation of elements in an array in different number of threads were compared.The calculation cost was obtained with the static method currentTimeMillis() in the system class.Given the definite number of addend,based on the most popular operating systems such as Linux,Windows 2000 Advanced Server,Windows XP Professional,the experiments show that not the more the number of the threads is,the better the efficiency is.In the mean... |
