Java中通过ZipOutputStream类如何将多个文件打成zip

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
public class ZipOutputStreamExample {
    public static void main(String[] args) {
        String file1Path = "/path/to/file1.txt";
        String file2Path = "/path/to/file2.txt";
        String zipOutputPath = "/path/to/output.zip";
        try (FileOutputStream fos = new FileOutputStream(zipOutputPath);
             ZipOutputStream zipOut = new ZipOutputStream(fos);
             FileInputStream fis1 = new FileInputStream(file1Path);
             FileInputStream fis2 = new FileInputStream(file2Path)) {
            addToZipFile(file1Path, fis1, zipOut);
            addToZipFile(file2Path, fis2, zipOut);
            System.out.println("文件成功添加到ZIP文件！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    private static void addToZipFile(String filePath, FileInputStream fis, ZipOutputStream zipOut)
            throws IOException {
        ZipEntry zipEntry = new ZipEntry(filePath);
        zipOut.putNextEntry(zipEntry);
        byte[] bytes = new byte[1024];
        int length;
        while ((length = fis.read(bytes)) >= 0) {
            zipOut.write(bytes, 0, length);
        }
        zipOut.closeEntry();
        fis.close();
    }
}
