我想比较两个元组

Question

我正在尝试编写一个函数来比较相似类型的元组.

def compareTuples(tuple1: (String, String, Int), tuple2: (String, String, Int)): (String, String, Int) = {
   // if tuple1.Int < tuple2.Int return tuple1 else tuple2.
}

如何访问每个元组中的第三个元素或int？

谢谢

Answer 1

要在一个元组访问的值t,你可以使用t._1,t._2等等.

对你而言会导致

def compareTuples(tuple1: (String, String, Int), tuple2: (String, String, Int)): (String, String, Int) = {
   if (tuple1._3 < tuple2._3) tuple1 else tuple2
}
