写一个zip压缩流

package com.t48.next.partice;

import java.io.*;
import java.util.zip.*;


public class ZipCompress {

public static void main(String[] args) {

try {

//建立输出文件流

FileOutputStream fileout = new FileOutputStream("peng.zip");

//建立冗余流

CheckedOutputStream checkedOut = new CheckedOutputStream(fileout,new CRC32());

//create zip stream
ZipOutputStream zipOut = new ZipOutputStream(new BufferedOutputStream(checkedOut));

//set commenet Content

zipOut.setComment("this is a java zipping test file");

//file name

String filename="E:\\demo\\src\\com\\t48\\next\\partice/ZipCompress.java";

//read compress filestream

BufferedReader in = new BufferedReader(new FileReader(filename));

//建立压缩实体
zipOut.putNextEntry(new ZipEntry(filename));

int ch;

while((ch=in.read())!=-1){

zipOut.write(ch);
}
//关闭文件流,and for free Resource

in.close();
zipOut.close();

} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
