如何关闭构造函数框架？

Question

public class RainfallStudy extends JFrame{
/**
 * Declare global variables
 */
int x = 20, y = 567; //starting location for the title 
int xSpeed = 20, ySpeed = 20; // the speed for x and y directions
int delay = 20; // to slow down my title 
ImageIcon BackGnd, pic; // variables for the pictures

/**
 * Constructor to build the frame
 */
public RainfallStudy() {
    // this builds a window with a title
    super("Weather Report");
    setSize(1000,567);

    //loading the picture files
    BackGnd = new ImageIcon ("weatherBack.png");
    pic = new ImageIcon ("weatherIcon.png");

    setResizable(false);
    setVisible(true);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
}

这就是我制作框架的方式，然后我在public void paint(Graphics g)中制作了动画。

现在，在我使用new RainfallStudy(); , window 在 animation 完成后保持打开状态，如何手动关闭它？

Answer 1

在 RainfallStudy 实例上调用dispose或setVisible是否有效？ 例如：

RainfallStudy rs = new RainfallStudy();
rs.setVisible(false);
