Answer 1

Answer:

Compilation error

Explanation:

Two variables with the same name can’t be created in a class.

Assuming we can declare two instance variables in a class with the same name, what are the effects?

If the first problem is resolved, i.e., by referring to the two variables uniquely, how can you refer to a specific variable among the two? The next issue arises when it becomes very difficult to tell which variable you are working for.

Therefore, if it were possible, it would not be a good idea to declare two instance variables with the same name. However, if you try to define it, the compiler will produce an error claiming that another variable with the identical name has already been declared.

As a result, we cannot declare two instance variables in a class with the same name.
