I have a string that contains some values .
for example : X1,X2,X3,X4
each of these values have predefined set
so the string could be 1128 , or 2323 and so on
If I have the string 1?23 I want to get all possible strings like 1123 ,1223, 1323, 1423
this should scale also if I have more than ? in the string
Re: set combination
Just as you were told on the OTN, your question doesn't pertain to Java programming.
If you have a Java question, ask it. Otherwise this thread too will be closed.
