在.txt文件上写入数据

Question

我试图将值(在文本区域中键入)存储到txt文件中.以下代码正在创建program.txt文件,但数据未写入其中.我究竟做错了什么？

另外,如果我想在用户指定的.txt文件中保存这些值,怎么办呢？

b2.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent arg0) {
            try {

                o = new BufferedWriter(new FileWriter("program.txt"));

                o.write(t1.getText());
                o.write(",");
                o.write(t2.getText());
                o.write(",");
                o.write(t3.getText());
                o.write(",");
                o.write(t4.getText());
                o.write(",");
                o.write(t5.getText());
                o.write(",");
                o.write(t6.getText());
                o.write(",");
                o.write(t7.getText());
                o.write(",");

            }
             catch (IOException e){
                e.printStackTrace();
            }

你必须使用BufferedWriter关闭你的BufferedWriter#close()

o.close();
