java 子类父类关于静态方法调用
public class Cat
{
protected static String color = "random";

public Cat() { }

public void showCatColor()
{

System.out.println("Cat:" + color);

}
public static void showColor()
{

System.out.println("Cat:" + color);

}
}

public class WhiteCat extends Cat
{

protected static String color = "white";

public WhiteCat()
{
super();
}

public void showCatColor()
{

System.out.println("WhiteCat:" + color);
}

public static void showColor()
{

System.out.println("WhiteCat:" + color);

}

}



WhiteCat whiteCat = new WhiteCat ;

Cat cat = whiteCat ;

cat.showColor();
cat.showCatColor();

执行结果为：Cat:random
WhiteCat:white


为什么cat.showColor()的执行结果是Cat:random，二不是WhiteCat:white















[解决办法]
因为静态方法没有多态的特性。。
