Javaコード：

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.charset.Charset;

File[] files = new File(“D:\\iphonegame").listFiles();
File f=new File(“D:\\iphonegame.zip");
try {

zipOut = new ZipOutputStream(fos,Charset.forName(“utf-8"));
} catch (FileNotFoundException e1) {
e1.printStackTrace();
f.delete();
return;
}

for (int i = 0; i < files.length; i++) {
