案例：拆分身份证号的秘密
- 倒数第二个数 奇数：男；偶数：女
object class2{
def getGender(idCard:String):String = {
val g = idCard.substring(16,17).toInt
if(g % 2 == 1){
"男"
}else{
"女"
}
}
def main(args: Array[String]): Unit = {
val idCard = "320324200606214419"
val gender = "女"
val birthday = "06.21"
val age = 19
val province = "湖北"
val zodiac= "双子"
println(s"---------------------")
println(s" 籍贯: ${province}")
println(s" 性别: ${gender}")
println(s" 年龄：${age}")
println(s" 生日：${birthday} ")
println(s" 星座：${zodiac}")
println(s"---------------------")
}
}
若想用身份证号码知道籍贯
object class2{
def getGender(idCard:String):String = {
val g = idCard.substring(16,17).toInt
if(g % 2 == 1){
"男"
}else{
"女"
}
}
def getProvince(idCard:String):String = {
val code = idCard.substring(0,2)
val map = Map("11"->"北京",
"12"->"天津",
"13"->"河北",
"14"->"山西",
"15"->"内蒙古",
"21"->"辽宁",
"22"->"吉林",
"23"->"黑龙江",
"31"->"上海",
"32"->"江苏",
"33"->"浙江",
"34"->"安徽",
"35"->"福建",
"36"->"江西",
"37"->"山东",
"41"->"河南",
"42"->"湖北",
"43"->"湖南",
"44"->"广东",
"45"->"广西",
"46"->"海南",

"64"->"宁夏",
"65"->"新疆",
"71"->"台湾",
"81"->"香港",
"82"->"澳门")
map.getOrElse(code,"未知")
}
def main(args: Array[String]): Unit = {
val idCard = "320324200606214419"
val gender = "女"
val birthday = "06.21"
val age = 19
val province = getProvince(idCard)
val zodiac= "双子"
println(s"---------------------")
println(s" 籍贯: ${province}")
println(s" 性别: ${gender}")
println(s" 年龄：${age}")
println(s" 生日：${birthday} ")
println(s" 星座：${zodiac}")
println(s"---------------------")
}
}
当然，可以以此类推，来知道生日，星座，年龄
- 我将身份证号改成320324200603034419
- 输出结果改变成“03.03”和“双鱼座”
