java - Convert json decimal number to short with hexadecimal value -

i have jsonobject contains string decimal value this:

private static registerin parseregisterin(jsonobject object) {     registerin toreturn = new registerin();     try {         toreturn.setusername(object.getstring("username"));         toreturn.setcertificate(new short(integer.tohexstring(object.get("certificate"))));     } catch (jsonexception e) {         e.printstacktrace();     }     return toreturn; } 

the certificate object value 15879 corresponds 3e07 in hexadecimal. want recover jsonobject , save in short attribute. , has that.

i've tried access parameter , recover posted above, following exception:

java.lang.numberformatexception: invalid int: "3e07"

how can decimal value, convert hexadecimal, , save in short value?

note:

toreturn.setcertificate(...) 

is short type.

you need use,

short.parseshort(object.getstring("certificate"), 16);
