set,get方法对封装数据进行操作
例如：private float Screen
public void setScreen(float newScreen){ Screen= newScreen; }
public float getScreen(){ return Screen;}
调用时：
phone.setScreen(6.4f);
System.out.println("Screen:"+phone.getScreen());

查看全部评论phone.Screen=6.4f; System.out.println("Screen:"+phone.Screen); 调用时，这样也能正常运行输出，请问封装了就一定要用set和get来操作数据吗？
