我在使用properties类中的store方法和setproperties方法时遇到了一些问题
我要把界面上输入的数据按照下面这种方式更新指定文件中相关数据时,下面的这个button中的功能该怎样实现?(请大家指点指点...)
 void button1_actionPerformed(ActionEvent e) {
    try {
      Properties props = new Properties();
      OutputStream out = new FileOutputStream("TestForExecuted.properties");
      props.setProperty("jrun.url",textField1.toString());
      props.setProperty("STOCKACCOUNT",textField2.toString());
      props.setProperty("CONTRACTNO",textField3.toString());
      props.setProperty("EXECUTEDNO",textField4.toString());
      props.setProperty("INSTRCODE",textField5.toString());
      props.setProperty("PRICE",textField6.toString());
      props.setProperty("QTY",textField7.toString());
      props.setProperty("EXSEAT",textField8.toString());
      props.setProperty("EVENT",textField9.toString());
      props.setProperty("EXBOARD",comboBox1.getSelectedItem().toString());
      props.setProperty("TXNTYPE",comboBox2.getSelectedItem().toString());
      //props.store(;
    }
    catch (Exception ex) {
      ex.printStackTrace();
    }

props.store(out,"whatever you want");
