多重構(gòu)造函數(shù)
多重構(gòu)造函數(shù)需要有一個主函數(shù)藕畔，和N個次函數(shù)
次函數(shù)將委托給主函數(shù)
委托關(guān)系用this關(guān)鍵詞表示
class MyBean {
var name: String = ""
var age: Int = 0
//缺省
var sex = false

構(gòu)造函數(shù)使用
普通構(gòu)造函數(shù)
//填值，相當(dāng)于setter
var tb = MyBean()
tb.age = 12
tb.name = "ZhangSan"
tb.sex = true
//取值癞尚，相當(dāng)于getter
var zsName = tb.name
var zsAge = tb.age
var zsSex = tb.sex
多重構(gòu)造函數(shù)
var bean1 = MyBean()
var bean2 = MyBean("zhangsan")
var bean3 = MyBean("zhangsan",14,false)
