Two numbers, num1 and num2, are said to be "friendly" if the sum of proper factors of num1 is equal to num2 and the sum of the proper factors of num2 is equal to numt. The method main below is to print either "Friendly" or "Not Friendly" to indicate whether two integer command line inputs, num1 and num2, are "friendly". Complete main so that is works as intended. You must call method sumOfDivisors in your solution. You may assume that the method sumOfDivisors returns the sum of the proper factors of its integer parameter. public class Friendly { Run | Debug public static void main(String [] args){ // WRITE YOUR CODE HERE } /* This method returns the sum of the proper divisors of n. A proper divisor is a number between 1 and n-1 inclusive that Divides into n evenly. YOU DO. NOT HAVE TO WRITE THIS CODE. Assume this method works as intended. */ public static int sum0fDivisors(int n){

Question
### Determining Friendly Numbers in Java

**Concept Overview:**

Two numbers, `num1` and `num2`, are considered "friendly" if the sum of the proper factors of `num1` is equal to `num2` and the sum of the proper factors of `num2` is equal to `num1`.

**Coding Task:**

The task is to complete the `main` method so that it determines whether two integer command-line inputs, `num1` and `num2`, are "friendly". You must call the `sumOfDivisors` method to achieve this.

**Assumptions:**

- The method `sumOfDivisors` is provided and returns the sum of proper factors of its integer parameter.

**Java Code Structure:**

```java
public class Friendly {
    public static void main(String[] args){
        // WRITE YOUR CODE HERE
    }
    
    /*
    This method returns the sum of the proper divisors of n.
    A proper divisor is a number between 1 and n-1 inclusive that divides n evenly.
    YOU DO NOT HAVE TO WRITE THIS CODE.
    Assume this method works as intended.
    */
    public int sumOfDivisors(int n) {
        // Simulated implementation
    }
}
```

**Explanation:**

- **Main Method:** This is where you will write the logic to check if the given numbers are friendly.
- **sumOfDivisors Method:** This function calculates the sum of all proper divisors of a number. Proper divisors are those numbers that divide the given number evenly, excluding the number itself.
