This error message usually occurs when a method in a subclass is intended to override a method in its superclass or interface, but the method signature (i.e., the method name, parameter types, and return type) does not match exactly with the method in the superclass or interface.
In the case of the method removeComplaint(Complaint) of type ComplaintDaoImpl, it means that this method is supposed to override a method from its superclass or interface, but the method signature is not identical to the method it is supposed to override.
To fix this error, you need to ensure that the method signature of the removeComplaint(Complaint) method in the ComplaintDaoImpl class matches exactly with the method it is supposed to override in its superclass or interface. This includes the method name, parameter types, and return type.
For example, if the removeComplaint(Complaint) method is supposed to override a method in an interface called ComplaintDao, the method signature in the ComplaintDaoImpl class should look like this:
public void removeComplaint(Complaint complaint) {
// implementation code here
}
Note that the method name, parameter type (Complaint), and return type (void) match exactly with the method in the ComplaintDao interface.
By ensuring that the method signature matches exactly with the method it is supposed to override, you can eliminate the "method must override or implement a supertype method" error and ensure that your code functions as intended.
