java - Cannot find associated value in a hashmap from a passed in key -

-

i working existing code in eclipse project. in method below called cardtypeforpbfvalue(), cannot find key in hashmap though can see while debugging code. pbfvaluemap populated follows:

[1=atm, 2=debit, 3=credit, 4=payroll]

i'm not sure why cannot associated value of credit when i'm passing in value of 3 in cardtypeforpbfvalue() below. getting value of null.

any help/direction appreciated.

here code i'm working with:

public static enum cardtype {     credit(3),     atm(1),     debit(2),     payroll(4);     cardtype(int pbfvalue) {         this.pbfvalue = (short) pbfvalue;     }      public static hashmap<short, cardtype>  pbfvaluemap = new hashmap<short, cardtype>();     static {         (cardtype cardtype : cardtype.values()) {             short value = cardtype.pbfvalue;             pbfvaluemap.put(cardtype.pbfvalue, cardtype);         }     }      public static cardtype **cardtypeforpbfvalue**(int pbfvalue) {         cardtype returnvalue = pbfvaluemap.get(pbfvalue);         if (returnvalue == null) {             returnvalue = debit;         }         return returnvalue;     }      public short    pbfvalue; }

you're looking integer, put short map. try this:

public static cardtype cardtypeforpbfvalue(int pbfvalue) {     short shortpbfvalue = (short) pdbvalue;     cardtype returnvalue = pbfvaluemap.get(shortpbfvalue);     ... }

better yet, stop using int everywhere (or stop using short map) - consistent in type want use.
