The Record-addressable random access file ( RARA ) is a new-type file in FORTRAN. It combines the advantages of the sequential and direct files, and provides a more efficient means for the users in their record unequal in length in the random access file. 记录可寻址随机访问文件是一种新型FORTRAN文件,它集中了顺序与直接文件两者的优点,为用户随机访问文件中不等长记录提供了更为有效的手段。
Through the file system classes, a Java program can open an input or output stream, open a file for random access, list the contents of a directory, and do other common file system tasks. 通过文件系统类,Java程序能打开一个输入或输出流,打开一个文件进行随机访问,列示目录内容,以及执行其他常规的文件系统任务。
