java压缩文件夹下的所有文件和选定文件

        String zipFileName = "D:\\test.zip";  //压缩后的zip文件

        test book = new test();
        try {
            book.zip(inputFileName, zipFileName);
        } catch (Exception ex) {

        }
    }

org.apache.tools.zip.ZipOutputStream 
和ZipEntry在ant.jar里，能解决中文问题，当然，你也可以使用java.util.zip下的，只是中文文件的话.会产生乱码，并且压缩后文件损坏
