继承

A：看程序写结果

class Student {
    static {
       System.out.println("Student 静态代码块");         
     }
    {
       System.out.println("Student 构造代码块");         
     }
    public Student(){
          System.out.println("Student 构造方法");      
    }
}
class Demo2_Student(){
    static {
        System.out.println("Demo2_Student静态代码块);
    }
    public static void main(String[] args){
        System.out.println("我是main方法");
        
        Student s1 = new Student();
        Student s2 = new Student();
    }
}
