刚刚做了个类似功能，与大家分享下，大家多提意见:

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

public class UnZip {
  static final int BUFFER = 2048;     //设置缓冲流
  public static String[] unZip(String path) {
      String[] list = null;
      String patht = new String("文件路径");
    try {
      BufferedOutputStream dest = null;
      FileInputStream fis = new FileInputStream(path);   //获得输入流
      ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
      ZipEntry entry;
      while ( (entry = zis.getNextEntry()) != null) {
        int count;
        byte data[] = new byte[BUFFER];    //开始读入
        // 分文件写到磁盘
        FileOutputStream fos = new FileOutputStream(patht+entry.getName());
        dest = new BufferedOutputStream(fos, BUFFER);
        while ( (count = zis.read(data, 0, BUFFER))
               != -1) {
          dest.write(data, 0, count); 
        }
        //关闭流
        dest.flush();
        dest.close();
      }
      zis.close();
      File f = new File(patht);
      list = f.list(); //返回由path指定路径里的所有文件名和目录名
    }
    catch (Exception e) {
      e.printStackTrace();
    }
    return list;
  }

}
