   https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Object.html#hashCode()
   
   > Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. **This integer need not remain consistent from one execution of an application to another execution of the same application.**
   
   As the javadoc of `hashCode` shows, "This integer need not remain consistent from one execution of an application to another execution of the same application."
