How to get path to save a file from user?
提问by Supereme
I'm developing an application in which I want to create an 'MS-EXCEL' file and for that I want the name for the file to be given by user and later on I want to provide an option to the user to save at the path where it wants. I know about JFileChooser but it only allows to select a file from the existing files whereas I want to save. What can be the way? Please give me some brief description.
我正在开发一个应用程序，我想在其中创建一个“MS-EXCEL”文件，为此我希望用户提供文件的名称，稍后我想为用户提供一个选项以保存在它想要的路径。我知道 JFileChooser 但它只允许从现有文件中选择一个文件，而我想保存。有什么办法？请给我一些简短的描述。

You can use JFileChooser.setFileSelectionModeto allow selection of either files, directories, or both files and directories.
您可以使用JFileChooser.setFileSelectionMode来允许选择文件、目录或文件和目录。
You can also type in the name of a file that doesn't already exist.
您还可以键入尚不存在的文件的名称。

JFileChooser chooser = new JFileChooser();
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
int option = chooser.showSaveDialog(null);
if (option == JFileChooser.APPROVE_OPTION)
{
// do soemthing
}
