Java IO 之 ZipFile/ZipInputStream/ZipOutputStream

http://blog.csdn.net/mhl29/article/details/6781229

public void runZipInputStream() throws IOException {

//1. 创建zip输入流

ZipInputStream zin = new ZipInputStream(new FileInputStream("IOTest.zip"));

ZipEntry ze;

//2. 逐个处理条目

while ((ze = zin.getNextEntry()) != null) {

//测试： 输出条目的信息

System.out.printf("条目信息： 名称%1$b, 大小%2$d, 压缩时间%3$d \n", ze.getName(), ze.getSize(), ze.getTime());

//3. 操作文件内容-输出、处理

FileInputStream fin = new FileInputStream(ze.getName());

byte[] buffer = new byte[4096];

int len;

while ((len = fin.read(buffer)) != -1) {

System.out.print(new String(buffer, 0, len));

}

}
