class DataInputStream 数据输入流允许应用程序以与机器无关方式从底层输入流中读取基本 Java 数据类型。 class FileInputStream FileInputStream 从文件系统中的某个文件中获得输入字节。 class FilterInputStream FilterInputStream 包含其他一些输入流,它将这些流用作其基本数据源,它可以直接传输数据或提供一些额外...

In order to create a file input stream, we must import the java.io.FileInputStream package first. Once we import the package, here is how we can create a file input stream in Java. 1. Using the path to file FileInputStream input = new FileInputStream(stringPath); Here, we have ...

FileInputStream和FileOutputStream提供附着在一个磁盘文件的输入流和输出流。只需向其构造器提供文件名或文件的完整路径名。如:FileInputStream in=new FileInputStream("data.txt"); Java使用某些流从文件或外部位置获取字节,而用其他流将字节组装到更有用的数据类型中。
