How to implement two interfaces with methods having the same signatures in one class?

Answer from AI

In Java, a class can implement multiple interfaces, even if they contain methods with the same signatures. In this case, it is sufficient to implement one method that satisfies both interfaces. For example:

interface InterfaceA {
    void doSomething();
}

interface InterfaceB {
    void doSomething();
}

public class MyClass implements InterfaceA, InterfaceB {
    @Override
    public void doSomething() {
        System.out.println("Implementation of the method for both interfaces");
    }
}

If the interfaces contain methods with the same name but different default implementations, then the class must explicitly override this method and choose the desired implementation.
