Question

我有以下开关声明

    switch (points) {
       case 0: name = "new"; break;
       case 1..14: badgeName = "bronze-coin"; break;
       case 15..29: badgeName = "silver-coin"; break;
       default: badgeName = "ruby";
    }

我希望第一种情况（案例0）包含小于或等于0的点。如何在Groovy中执行此操作？

Answer 1

switch(points)
{
    case Integer.MIN_VALUE..0: badgeName = "new"; break;
    case 1..14: badgeName = "bronze-coin"; break;
    case 15..29: badgeName = "silver-coin"; break;
    default: badgeName = "ruby";
}

Answer 2

case { it instanceof Integer && it < 0 }:

少于Groovy case / switch语句
