Construction method introduction

构造方法(构造器)
创建对象的时候，要执行的方法
格式
1、方法名与类名相同，大小写也需要一致
2、没有返回值类型，连void都没有
3、没有具体的返回值(不能由return语句带回结果数据)
构造方法的执行时机
在创建对象的时候，被调用执行
每创建一次对象，就会执行一次构造方法构造方法的作用
1、本质的作用: 创建对象
2、结合执行时机: 可以创建对象的时候，给对象中的数据初始化
构造方法的注意事项
1、一个类中，没有编写构造方法，系统将会提供一个[默认的][无参数]的构造方法
2、一个类中，如果手动编写了构造方法，系统将不会再提供那个默认的无参构造了
建议: 编写类的时候，无参构造，带参构造，全部手动给出
3、构造方法不允许手动调用
