java - 在文本区域中显示控制台信息

Question

 int day = Integer.parseInt(inputDay.getText());
 int month = Integer.parseInt(inputMonth.getText());
 int year = Integer.parseInt(inputYear.getText());

 int dayNow = Integer.parseInt(inputDayNow.getText());
 int monthNow = Integer.parseInt(inputMonthNow.getText());
 int yearNow = Integer.parseInt(inputYearNow.getText());

 //total.setText(day + "/" + day + "=" + day/day);
 System.out.println(((yearNow-year)*365)+((monthNow-month)*30)+(dayNow-day));

我正在尝试让System.out.println显示在文本区域

Answer 1

使用 JTextArea 并实现 setText() 方法...试试这个

JTextArea t = new JTextArea();
t.setText(Integer.toString(((yearNow-year)*365)+((monthNow-month)*30)+(dayNow-day)));
