Java核心类库-IO-合并流

Posted 2020-09-19

合并流/顺序流（sequenceInputStream）：

就是把多个输入流，合并成一个流对象。

 1 public class SequenceInputStreamDemo {
 2     public static void main(String[] args) throws Exception {
 3         //创建顺序流对象
 4         SequenceInputStream in = new SequenceInputStream(new FileInputStream("stream.txt"),
 5                 new FileInputStream("stream2.txt"));
 6 
 7         byte[] buffer = new byte[1024];
 8         int len = -1;
 9         while ((len = in.read(buffer)) != -1){
10             System.out.println(new String(buffer,0,len));
11         }
12         in.close();
13     }
14 }
