I think everything else is correct but something is wrong with the import. Here is the error it's giving me :
./CallCenter.java:3: error: '.' expected import CustomerSupportRep; ^ ./CallCenter.java:3: error: ';' expected import CustomerSupportRep; ^ Note: ./MockyQueue.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 2 errors

}
public void acceptCustomer(Customer customer) {
CustomerSupportRep csr;

newrep.assist(customer);

Courses Plus Student 10,188 PointsOk I fixed the error. Now it throws a null pointer exception which I don't remember what that means exactly. How do I fix that?
