当我们使用Java往文件写入数据的时候,我们有两种方式,使用FileOutputStream或FileWriter. FileOutputStream: File fout = new File(file_location_string); FileOutputStream fos = new FileOutputStream(fout); BufferedWriter out = new BufferedWriter(new OutputStreamWriter(fos)); out.writ…

本文转载这里FileInputStream和FileOutputStream类需要注意的问题:  1.FileInputStream和FileOutputStream类分别用来创建磁盘文件的输入流和输出流对象,通过它们的构造函数来指定文件路径和文件名. 2.创建FileInputStream实例对象时,指定的文件应当是存在和可读的.创建FileOutputStream实例对象时,如果指定的文件已经存在,这个文件中的原来内容将被覆盖清除. 3.对同一个磁盘文件创建FileInputStream对象…

FileInputStream类和FileOutputStream类中,第一个类的源端和第二个类的目的端都是磁盘文件,它们的构造方法允许通过文件的路径名来构造相应的流.例如: FileInputSteam infile=new FileInputStream("myfile.dat"); FileOutputStream outfile=new FileOutputStream("results.dat"); 构造FileOutputStream对象时,对应的文件必…
