我只想制作一个基本的计数器,由于某种原因,我无法弄清楚如何在1到100之间绘制一个随机数.有人可以解释一下我要做什么来绘制1到100之间的随机数吗？

这就是我想到的:

int value;
private int count = 1;

Random rand;


}

为什么我的定时器出错了？在代码下方,它说明错误是什么.我无法弄清楚我做错了什么......任何人都可以帮助我

       import java.util.Timer;
       import javax.swing.ImageIcon;
       import javax.swing.JPanel;

       /**
        *
      * @author Rich
      */
     public class Board extends JPanel implements ActionListener{
         Dude p;
        Image img;
       Timer time;

        public Board() {
         p = new Dude();
        addKeyListener(new AL());
         setFocusable(true);
          ImageIcon i = new ImageIcon("images.jpg");
          img = i.getImage();
          time = new Timer(5,this);
          time.start();
        }

        public void actionPerformed(ActionEvent e) {
        p.move();
        repaint();
         }

基本上我得到的错误是

no  suitable constructor found for Timer(int,OurGame.Board)
constructor java.util.Timer.Timer(java.lang.String,boolean) is not applicable
  (actual argument int cannot be converted to java.lang.String by method …
