    • Non-static methods require an instance of the class to be created before they can be called.

    • Static methods cannot access instance variables, while non-static methods can.

    • Example: Math.sqrt() is a static method, while String.length() is a non-static m

  • Ans. 

    Java does not support multiple inheritance to avoid the diamond problem and maintain simplicity and clarity in the language.

    • Java supports single inheritance to prevent the diamond problem, where conflicts arise when a class inherits from two classes that have a common ancestor.
