JAVA匿名类实现接口及父类

匿名类继承一个父类：

class Person {
   public String toString() {
       return "This is a person";
   }
}

public class Student {
    @Test
    public void test() {
    	// 匿名内部类重写父类方法
        Person person = new Person() {
            @Override
            public String toString() {
                return "This is a student";
            }
        };
        System.out.println(person);
    }
}

匿名类实现一个接口：

interface Person {
    String toString();
}

public class Student {
    @Test
    public void test() {
        Person person = new Person() {
            public String toString() {
                return "This is a student";
            }
        };
        System.out.println(person);
    }
}
