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();
}
 }
