Java_代码块

• 代码块的好处和案列演示
  1.相当于另一种形式的构造器，可以做初始化操作
  2.提高代码的重用

  package com.java.static_;
   
  public class CodeBLock {
      public static void main(String[] args) {
          Movie movie = new Movie("让子弹飞");
          Movie movie1 = new Movie("让子弹飞",242);
   
      }
  }
   
   
  class Movie{
      private String name;
      private double price;
      private String director;
      {
          System.out.println("电影打开");
          System.out.println("正在加载广告");
      }
   
      public Movie(String name) {
          this.name = name;
      }
   
      public Movie(String name, double price) {
          this.name = name;
          this.price = price;
      }
   
      public Movie(String name, double price, String director) {
          this.name = name;
          this.price = price;
          this.director = director;
      }
   
   
   
   
  }
