将ZipEntry复制到新ZipFile的惯用方法是什么？

import java.io.*;
import java.util.zip.*;

public class ZipEntryCopy {
    public static void main(String[] args) throws IOException {
        File inputFile = new File("input.zip");
        File outputFile = new File("output.zip");

        try (ZipInputStream zin = new ZipInputStream(new FileInputStream(inputFile));
             ZipOutputStream zout = new ZipOutputStream(new FileOutputStream(outputFile))) {

            ZipEntry entry;
            while ((entry = zin.getNextEntry()) != null) {
                zout.putNextEntry(new ZipEntry(entry.getName()));

                byte[] buffer = new byte[1024];
                int len;
                while ((len = zin.read(buffer)) > 0) {
                    zout.write(buffer, 0, len);
                }

                zout.closeEntry();
                zin.closeEntry();
            }
        }
    }
}
