You can use a JFileChooser to be able to select a file from a dialog box.

您可以使用JFileChooser从对话框中选择文件。

Assuming you want to launch it outside a Java Swing application, you could proceed as next:

假设您想在Java Swing应用程序之外启动它,您可以继续下一步:

final JFileChooser fc = new JFileChooser();
// Open the dialog using null as parent component if you are outside a
// Java Swing application otherwise provide the parent comment instead
int returnVal = fc.showOpenDialog(null);
if (returnVal == JFileChooser.APPROVE_OPTION) {
    // Retrieve the selected file
    File file = fc.getSelectedFile();
    try (FileInputStream fis = new FileInputStream(file)) {
        // Do something here
    }
}
