方法名:getEnumConstant

Numbers.getEnumConstant介绍

[英]Returns a numeric constant for the given type. The constants are #BIG_DECIMAL, #BIG_INTEGER, #DOUBLE, #FLOAT, #LONG, #INTEGER, #SHORT, #BYTE, #CHARACTER, #BOOLEAN, or #OTHERconstants for the given type. This is a commodity for usage in switch statements.
[中]返回给定类型的数值常量。对于给定的类型,常量是#大#十进制、#大#整数、#双精度、#浮点、#长、#整数、#短、#字节、#字符、#布尔值或#其他常量。这是一种用于switch语句的商品。
