Question

I am needing to check if a string does NOT contain any of these string possibilities:

MNC
BRA
LEB
MAR
RVC
WAY
GLZ
WWW
HYB

My current code :

 if(selectedLocation.equals("OTH"))
 {
    if(!currentClassLocation.equals("MNC") &&
                        !currentClassLocation.equals("BRA") &&
                        !currentClassLocation.equals("LEB") &&
                        !currentClassLocation.equals("MAR") &&
                        !currentClassLocation.equals("RVC") &&
                        !currentClassLocation.equals("WAY") &&
                        !currentClassLocation.equals("GLZ") &&
                        !currentClassLocation.equals("WWW") &&
                        !currentClassLocation.equals("HYB"))
                    {
                         //Awesome, I need this string! I operate on it here.
                    }
 }

Long story short, I can’t use a for-loop. Is there a way I can check if the string doesn’t contain any of these without iteration?

Use a HashSet:

Set<String> invalidSequences = new HashSet<String>();
invalidSequences.add("MNC");
invalidSequences.add("BRA");
invalidSequences.add("LEB");
// Remaining sequences ...

if (!invalidSequences.contains(currentClassLocation)) {
    // Awesome, I need this string...
}
