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();} }
