Switch case uses enumeration classes to compare

The reference codes are as follows ：

// adopt valueOf Method to get the concrete enumeration , This type It is the parameter to be matched that is actually passed in 
Enum enum = Enum.valueOf(type);
//switch The matching item in is the enumeration obtained above 
switch (enum) {
    
   // there case The matching conditions are matched with the enumeration instances we have defined 
   case enum1:
   case enum12:
 ...}
