使用图像在Java中创建.zip文件

Question

我正在创建一个Java程序，它从JFileChooser获取图像并创建包含所选图像的.zip文件。我用这段代码获取文件：

final JFileChooser fc = new JFileChooser();
    fc.setMultiSelectionEnabled(true);
    fc.setFileFilter(new FileNameExtensionFilter("Image files", "bmp", "png", "jpg")); 
    fc.setAcceptAllFileFilterUsed(false);  
    fc.showOpenDialog(null);
    File files[] = fc.getSelectedFiles();

我如何创建包含files[]数组文件的.zip文件？

感谢您的帮助：D。

Answer 1

File someFile = new File("someFile.zip");
File files[] = fc.getSelectedFiles();
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(someFile));

// Create the ZIP file first
try (ZipOutputStream out = new ZipOutputStream(bos)) {
    // Write files/copy to archive
    for (File file : files) {
        // Put a new ZIP entry to output stream for every file
        out.putNextEntry(new ZipEntry(file.getName()));
        Files.copy(file.toPath(), out);
        out.closeEntry();
    }
}
