1、下列程序的功能是显示单击“确定”按钮的次数，请将程序补充完整，实现题目的功能。
import java.applet.*;
import java.awt.* ;
import java.awt.event.* ;
public class Java3_2 extends Applet implements ActionListener
{
Int count=0 ;
Button b1=new Button(“确定”);
Label disp_count=new Label(“单击确定按钮”+String.valueof(count)+”次”);
//**********
//**********
}
2、下列的程序实现的功能是：当拖动滚动条的滑块时，在文本框中显示出滑块的位置值。请将程序补充完整。
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class ScrollbarDemo1 extends Applet implements AdjustmentListener
{
Scrollbar myslider=new Scrollbar(Scrollbar.HORIZONTAL,5,1,1,50);
TextField slider=new TextField();
public void init()
{
//*********************
       //**********************
}
public void adjustmentValueChanged(AdjustmentEvent e)
{
//***********************************
 

       //************************************
}
}
3、下面的程序可实现圆形向前移动的动画，但程序不完整，请将paint()方法补充完整，使之实现题目要求
import java.awt.*;
import java.applet.*;
public class Java3_1 extends Applet
{
int x, y;
public void start()
{
  x=10 ; y=20 ;
}
public void paint(Graphics g)
{
//**************
//**************
}
}

//随便写的不知道是不是符合要求
import java.applet.*;
import java.awt.*;
import java.awt.event.*;

public class Java3_2 extends Applet implements ActionListener {
    private static final long serialVersionUID = 71508092428059127L;

    int count = 0;

    Button b1 = new Button("确定");

    Label disp_count = new Label("单击确定按钮" + String.valueOf(count) + "次");

    public void init()
    {
        this.add(b1);
        this.add(disp_count);
        b1.addActionListener(this);
    }

   
    public void actionPerformed(ActionEvent e) {
        count++;
        disp_count.setText("单击确定按钮" + String.valueOf(count) + "次");
    }
}

import java.applet.*;
import java.awt.*;
import java.awt.event.*;

public class ScrollbarDemo1 extends Applet implements AdjustmentListener {
    /**
     *
     */
    private static final long serialVersionUID = 1L;

    Scrollbar myslider = new Scrollbar(Scrollbar.HORIZONTAL, 5, 1, 1, 50);

    TextField slider = new TextField();

    public void init() {
        this.add(myslider);
        this.add(slider);
        myslider.addAdjustmentListener(this);
    }

    public void adjustmentValueChanged(AdjustmentEvent e) {
        slider.setText(myslider.getValue() + "");
    }
}

import java.awt.*;
import java.applet.*;

public class Java3_1 extends Applet {
    /**
     *
     */
    private static final long serialVersionUID = 1L;

    int x, y;

    public void start() {
        x = 10;
        y = 20;
    }

    public void paint(Graphics g) {
        g.translate(x, y);
        x += 1;
    }
}

太感谢2楼了！！！！
