Java 文件解压缩实现代码

java实现压缩文件的解压缩操作，缺点是压缩文件内不能含有文件名为中文的的文件，否则会出现如下错误：

exception in thread "main" java.lang.illegalargumentexception: malformed
 at java.util.zip.zipcoder.tostring(unknown source)
 at java.util.zip.zipinputstream.readloc(unknown source)
 at java.util.zip.zipinputstream.getnextentry(unknown source)
 at com.javatest.techzero.gui.zipfiledemo.main(zipfiledemo.java:22)

代码：

package com.javatest.techzero.gui;

import java.io.file;
import java.io.fileinputstream;
import java.io.fileoutputstream;
import java.io.inputstream;
import java.io.outputstream;
import java.util.zip.zipentry;
import java.util.zip.zipfile;
import java.util.zip.zipinputstream;

public class zipfiledemo {
 @suppresswarnings("resource")
 public static void main(string args[]) throws exception {
  file file = new file("d:" + file.separator + "test.zip");
  file outfile = null;
  zipfile zipfile = new zipfile(file);
  zipinputstream zipinput = new zipinputstream(new fileinputstream(file));
  zipentry entry = null;
  inputstream input = null;
  outputstream out = null;
  while ((entry = zipinput.getnextentry()) != null) {
   system.out.println("开始解压缩" + entry.getname() + "文件。。。");
   outfile = new file("d:" + file.separator + entry.getname());
   if (!outfile.getparentfile().exists()) {
    outfile.getparentfile().mkdir();
   }
   if (!outfile.exists()) {
    outfile.createnewfile();
   }
   input = zipfile.getinputstream(entry);
   out = new fileoutputstream(outfile);
   int temp = 0;
   while ((temp = input.read()) != -1) {
   <span style="white-space: pre"> </span>//system.out.println(temp);
    out.write(temp);
   }
   input.close();
   out.close();
  }
  system.out.println("done!");
 }
