Java - InterfacesWhat happens if two interfaces have methods with the same signature and a class implements both?AThe class must override the method to resolve the conflict.BJava throws a compile-time error automatically.CThe class inherits both methods without conflict.DThe class can only implement one of the interfaces.Check Answer
Step-by-Step SolutionSolution:Step 1: Identify method conflict in multiple interfacesIf two interfaces have the same method signature, the implementing class faces a conflict.Step 2: Resolve conflict by overridingThe class must provide its own implementation to resolve the conflict explicitly.Final Answer:The class must override the method to resolve the conflict. -> Option AQuick Check:Method conflict resolution = A [OK]Quick Trick: Override conflicting methods when implementing multiple interfaces [OK]Common Mistakes:Assuming Java auto-resolves method conflictsIgnoring the need to override conflicting methodsThinking multiple inheritance is disallowed if methods clash
