class TestMore
{
public static void main(String [] args)
{
Child c =new Child();
System.out.println(c instanceof Father);[color=Red]//返回true，子类的对象属于父类的对象[/color]
System.out.println(c instanceof Child);//返回true
Father f =new Child();
System.out.println(f instanceof Father);//返回true
System.out.println(f instanceof Child);//返回true
Father ff =new Father();
System.out.println(ff instanceof Father);
System.out.println(ff instanceof Child); [color=Red]//false，父类的对象不属于子类的对象[/color]
}
}
class Father
{
}
class Child extends Father
{
}
