Question

有人可以帮我吗？我想在按btnSubmit时将所有数据（如文本字段，复选框，radioButtton，滚动列表）保存在.txt文件中。

btnSubmit.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) {
            if(textField.getText().isEmpty()||(textField_1.getText().isEmpty())||(textField_2.getText().isEmpty())||(textArea_1.getText().isEmpty())||((radioButton_1.isSelected())&&(radioButton.isSelected()))||(comboBox.getSelectedItem().equals("Select")))
                JOptionPane.showMessageDialog(null, "Data Missing");
            else 

             JOptionPane.showMessageDialog(null, "Data Submitted");



        }
    });

Answer 1

BufferedWriter writer = new BufferedWriter(new FileWriter(your_file, append)); 
writer.write(your_string);
writer.close();

对于btnSubmit：

btnSubmit.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {
        if(textField.getText().isEmpty()||(textField_1.getText().isEmpty())||(textField_2.getText().isEmpty())||(textArea_1.getText().isEmpty())||((radioButton_1.isSelected())&&(radioButton.isSelected()))||(comboBox.getSelectedItem().equals("Select")))
            JOptionPane.showMessageDialog(null, "Data Missing");
        else {
         JOptionPane.showMessageDialog(null, "Data Submitted");
         BufferedWriter writer = new BufferedWriter(new 
         FileWriter(new File("file.txt"), append)); 
         writer.write(textField.getText());
         writer.close();
        }
});

但是Google搜索会提供比我更好的答案。
