我对java很陌生，但这不是重点，我试图让我的开始按钮打开我的显示肉，但我不知道怎么做。我只是不知道如何编写可以做到这一点的代码，所以我只是把它放在油漆中作为测试，看看我的按钮是否工作。

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

public class Game2 extends Applet implements KeyListener, ActionListener
{
Color color1 ;
Image theworld2, BOAT, life, life2,plane;
char ch='*';
int a,s,d,w,i,k,l,j,X,Y,X1,Y1 ,b,count, lifex ,lifey,planeX,planeY,planeX1,planeY1,planeX2,planeY2;
String sr="Hello";
Button Start ;
public void init ()
{
    setSize(1700,900);
    requestFocus (); //make applet the active component for key events
    addKeyListener (this); //listen to key events
    theworld2 = getImage(getDocumentBase(),"theworld2.jpg");
    BOAT = getImage(getDocumentBase(),  "BOAT.jpg");
    life2 = getImage(getDocumentBase(), "life2.jpg");
    plane = getImage(getDocumentBase(), "plane.jpg");
    color1 = new Color(255,255, 255);
    play (getCodeBase(), "sinking.aiff");
    Start = new Button("Click me to start!");
    Start.addActionListener(this);
    add (Start);

    lifex = (int) (Math.random () *1400 );
    lifey = (int) (Math.random () *800 ) ;
    X = (int) (Math.random () *1400 );

    planeY2 = (int) (Math.random () *800 ) ;

    if (X >lifex && X <lifex +30 && Y> lifey && Y < lifey +30)
