Java

Question

我想获取用户在Java中保存的文件的完整路径。 这是方法保存的代码，它工作正常但实际上我需要获取用户保存文件的路径。有人可以帮助我：

import java.awt.*;
import java.io.*;
import javax.swing.*;

public class FileChooserSave {
    private static void createAndShowUI() {
        final JFileChooser chooser = new JFileChooser(new File(".")) {
            public void approveSelection() {
                if (getSelectedFile().exists()) {
                    int n = JOptionPane.showConfirmDialog(this, "Do You Want to Overwrite File?", "Confirm Overwrite",
                            JOptionPane.YES_NO_OPTION);

                    if (n == JOptionPane.YES_OPTION)
                        super.approveSelection();

                } else
                    super.approveSelection();
            }
        };

        chooser.setSelectedFile(new File(""));
        int returnVal = chooser.showSaveDialog(null);

        if (returnVal == JFileChooser.APPROVE_OPTION) {
            System.out.println(chooser.getSelectedFile());
        }
    }
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                createAndShowUI();
            }
        });
    }
}

Answer 1

您可以使用此方法获取绝对路径：

myFileChooser.getSelectedFile().getAbsolutePath()

Answer 2

以下是来自JFileChoose

的绝对路径的Java代码示例

JFileChooser fileChooser = new JFileChooser();
fileChooser.setDialogTitle("Specify a file to save");   
 
int userSelection = fileChooser.showSaveDialog(parentFrame);
 
if (userSelection == JFileChooser.APPROVE_OPTION) {
    File fileToSave = fileChooser.getSelectedFile();
    System.out.println("Save as file: " + fileToSave.getAbsolutePath());
}

希望它有所帮助...
