Explanation of the Code:
This program demonstrates how to use recursion in Java to calculate the power of a number. The recursion concept allows the program to repeatedly call the same method until reaching a base case (when the exponent is 0).

Key Parts of the Code:
1. **`power` Method (Recursive Function)**:
This method takes two parameters, `base` and `exponent`.
It multiplies the `base` with the result of `power(base, exponent - 1)`, recursively calling itself.
The base case occurs when `exponent == 0`, where it simply returns 1, as any number raised to the power of 0 is 1.

2. **User Input**:
The `Scanner` class captures the base and exponent values from the user.

3. **Calculation and Output**:
Once the user inputs the values, the program uses the recursive `power` method to compute the result and then displays it.
