Why can't method override be used without inheritance?
Overriding a method means that you are replacing an existing or virtual method that has already been defined in the parent object class, so without using inheritance, there can be no existing method to override.
Any method in a super class can be overridden in its subclass?
False.Any method declared as final cannot be overridden by any subclasses.You also cannot technically override a private method. While your subclass can have a method with the same definition as a private method in the superclass, it does not actually override that method.
Why must you override the hashcode method while overriding the equals method?
Because, if two objects are supposed to be equal as per the equals() method, then the value returned by the hashCode() method must also be the same. This will not be the case if you override only the equals method and this can have some confusing effects when using those objects with hash related collections. So it is always a good idea to override the hashCode() method if you are providing an implementation for the equals method.
Is it possible to override the main method in Java?
Theoretically yes. You will use only one main method for your whole java application and hence such a situation will not come up in real life. Imagine: You have a main in class A and one more in class B which extends class A. When you try to run the class B, only that main method will be executed and not the main in class A. So this override is irrelevant and we cannot call class A's main method at all
