Java Piano模拟钢琴效果的完整源码,知识点:使用AudioClip类播放声音,使用Java MouseEvent类处理鼠标事件,使用Image类制作图片,使用fr a me类制作界面框架。运行后创建一个带有模拟钢琴键盘的面板，用户可以通过键盘或者鼠标来“敲击”钢琴键盘发出声音，也可以通过电脑键盘的组合键实现钢琴的高音。

　　编程思路：首先制作模拟钢琴的实例，生成程序界面：先通过语句Image m_ImgUp生成键盘、鼠标松开时显示的键盘图片，再通过语句Image m_ImgDown生成键盘、鼠标按下时显示的键盘图片，最后通过语句m_ImgUp=getImage(getDocumentBase(),"img/up.gif")和语句m_ImgDown=getImage（getDocumentBase（）,"img/down.gif"）加载图片，生成钢琴界面。然后模拟钢琴效果，模拟声音的播放，首先通过语句AudioClip[] m_AudioClip=new AudioClip[14]生成一个音频对象的数组，保存七个中音和七个高音的声调，最后，通过函数public void keyPressed(KeyEvent e)来响应按下键盘的动作，实现声音的播放-Complete source Java Piano Piano effects simulation , knowledge: Use AudioClip class to play sounds , using Java MouseEvent class handles mouse events , use the Image class to create an image , using the fr a me class production interface fr a mework. Create a panel with a simulated piano keyboard after running, the user through the keyboard or mouse to " tap " sound piano keyboard , piano treble can also be achieved through a combination of computer keyboard keys .

Programming ideas: first production examples simulate piano generating program interface : first m_ImgUp generated when the keyboard, mouse, keyboard, display pictures by loosening the statement Image, then m_ImgDown generated when the keyboard, mouse, keyboard, display pictures by pressing the statement Image, and finally through statement m_ImgUp = getImage (getDocumentBase (), "img/up.gif") and statements m_ImgDown = getImage (getDocumentBase (), "img/down.gif") load images , generate piano interface. Then the effect of sim
