Best way to “negate” an instanceof

Question

I was thinking if there exists a better/nicer way to negate an instanceof in Java. Actually, I\'m doing something like:

if(!(str instanceof String))         


        

Answer 1

ok just my two cents, use a is string method:

public static boolean isString(Object thing) {
    return thing instanceof String;
}

public void someMethod(Object thing){
    if (!isString(thing)) {
        return null;
    }
    log.debug("my thing is valid");
}
