多多复习多态的成员访问特点
class Fu
{
public void show()
{
System.out.println("fu show");
}
}
class Zi extends Fu
{
public void show()
{
System.out.println("zi show");
}
public void method()
{
System.out.println("zi method");
}
}
class Test
{
public static void main(String[] args)
{
Fu f = new Zi();
f.method();//编译错误,不能访问子类自有的成员
}
