我想弄清楚如何为摆动组件设置动画，使其从 a 点移动到 b 点。这是一个让红色 JPanel 从左向右移动的代码示例：

import java.awt.Color;
import java.awt.event.ActionEvent;

        square.setBounds(20,200,100,100);
        square.setBackground(Color.RED);

        Timer timer = new Timer(1000/60,new MyActionListener());
        timer.start();
        frame.setVisible(true);
    }

    public static class MyActionListener implements ActionListener{

        @Override
        public void actionPerformed(ActionEvent arg0) {
            square.setLocation(x++, 200);

        }

    }

    public static void …
