Java中创建ZIP文件的方法

java创建zip文件的代码如下如下：

import java.io.file;
import java.io.fileinputstream;
import java.io.fileoutputstream;
import java.io.ioexception;
import java.util.zip.zipentry;
import java.util.zip.zipinputstream;
import java.util.zip.zipoutputstream;
public class zipdemo {
 public static void main(string[] args) throws ioexception {
  file file = new file("test.zip");
  if(!file.exists())
  file.createnewfile();
  string string="test zip!";
  byte[] buffer =string.getbytes();
  fileoutputstream foutputstream = new fileoutputstream(file);
  zipoutputstream zoutput = new zipoutputstream(foutputstream);
  zipentry zentry = new zipentry("test.txt");
  zoutput.putnextentry(zentry);
  zoutput.write(buffer);
  zoutput.closeentry();
  zoutput.close();
 }
}

补充：下面看下java中创建zip文件，并向zip文件中写入并读取条目和数据

package file;
 import java.io.file;
 import java.io.fileinputstream;
 import java.io.fileoutputstream;
 import java.io.ioexception;
 import java.util.zip.zipentry;
 import java.util.zip.zipinputstream;
 import java.util.zip.zipoutputstream;
 public class zipdemo {
public static void main(string[] args) throws ioexception {
// todo auto-generated method stub
 file file = new file("test.zip");
 if(!file.exists())
 file.createnewfile();
 string string="my name is ysd!";
 byte[] buffer =string.getbytes();
 byte[] bufferinput =new byte[4096]; 
 fileoutputstream foutputstream = new fileoutputstream(file);
 zipoutputstream zoutput = new zipoutputstream(foutputstream);
 zipentry zentry = new zipentry("one.txt");
 zoutput.putnextentry(zentry);
 zoutput.write(buffer);
 zoutput.closeentry();
 zoutput.close();
 zipinputstream zinputstream = new zipinputstream(new fileinputstream(file));
 zipentry zipentry = null;
 while((zipentry=zinputstream.getnextentry()) != null)
 {
 system.out.println(zipentry.getname());
 zinputstream.read(bufferinput);
 system.out.println(new string(bufferinput));
 zinputstream.closeentry();
 }
 zinputstream.close();
}
 } 

总结
