In this noncompliant code example, multiple threads can invoke the setValues() method to set the a and b fields. Because this class does not test for integer overflow, a user of the Adder class must ensure that the arguments to the setValues() method can be added without overflow. (For more information, see guideline NUM00-J. Ensure that integer operations do not result in Detect or prevent integer overflow.)
