Java各代码块运行顺序

各代码块运行顺序

• 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();
  }
  }

Demo2_Student静态代码块
我是main方法
Student 静态代码块
Student 构造代码块
Student 构造方法
Student 构造代码块
Student 构造方法
