父类的静态方法能否被子类重写

父类的静态方法不能被子类重写

代码

Anim

public class Anim {

public static void test() {
System.out.println("Anim test static method!");
}

}

Dog

public class Dog extends Anim {

public static void test() {
System.out.println("Dog test static method!");
}

}

Main

public class TestMain {

public static void main(String[] args) {

Anim.test();

Dog.test();

}

}

输出

Anim test static method!
Dog test static method!

子类可以调用父类的静态方法

添加cat

public class Cat extends Anim {

}

main

public class TestMain {

public static void main(String[] args) {

Cat.test();

}

}

输出

Anim test static method!

子类对象调用静态方法

public class TestMain {

public static void main(String[] args) {

Dog a1 = new Dog();
a1.test();

System.out.println("----------------");

Anim a2 = new Dog();
a2.test();

}

}输出
