课后知识点回顾十二 流

流

1.输出字节流：OutputStream out = new FileOutputStream(f);

2.输入字节流：InputStream in = new FileInputStream(f);

4.转换流：OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream(f));

5.打印流：PrintStream ps = new PrintStream(new FileOutputStream(f));

6.合并流：SequenceInputStream  s = new SequenceInputStream(InputStream s1, InputStream s2);

7.压缩流：ZipOutputStream zops = new ZipOutputStream(new FileOutputStream(path2));
zops.putNextEntry(new ZipEntry(f.getName()));//为每一个被压缩的文件设置名字
zops.setComment("asdffads");//设置注释

8.序列化：就是将对象整体存储。
