We have a scenario in which several threads call a static method like the following one:
public static boolean isEmpty(final String s) {
return s == null || s.length() < 1;
}
Could it cause a problem of inconsistence if 100 threads call it?
No. This wont suffer from any concurrency problems.
1) The parameter you pass in is a String which is an immutable class (its value cannot be modified)
2) The method doesn’t try to modify any shared state
