How do I compare strings in Java?

1 view (last 30 days)
I've been using the == operator in my program to compare all my strings so far. However, I ran into a bug, changed one of them into .equals() instead, and it fixed the bug.
Is == bad? When should it and should it not be used? What's the difference? cummingslinda14 at

It's not bad. It just depends on what you want to do. That compares strings, as character arrays, on a character by character basis. There are other string functions that do it differently, like strcmp() and strcmpi() and strfind(). I encourage you to look those up in the help to see exactly what they do and how they differ from "==" and to see which is the right operation to do for your current need.
