In this lab, you will implement a method in Java named `calculateSimpleInterest`

within the `Main`

class. This method will calculate the simple interest given the principal amount, the rate of interest, and the time period.

### Requirements

**Method Name**: The method must be named`calculateSimpleInterest`

.**Parameters**: Three parameters should be passed to this method:`principal`

(double): The principal amount.`rate`

(double): The rate of interest.`time`

(double): The time period.

**Return Type**: The method should return a`double`

representing the calculated simple interest.**Output Precision**: The returned simple interest should be rounded to exactly**two decimal places**.

### Calculation Formula

The simple interest is calculated using the formula:

### Edge Cases and Examples

**Edge Case**: When any of the parameters (`principal`

,`rate`

, or`time`

) is zero, the returned simple interest should also be zero.**Example 1**: If`calculateSimpleInterest(2000, 5, 10)`

is called, the method should return`1000.00`

. This is because the simple interest for these values is calculated as ((2000 \times 5 \times 10) / 100 = 1000.00).**Example 2**: For`calculateSimpleInterest(10000, 3, 1)`

, the expected return value is`300.00`

, calculated as ((10000 \times 3 \times 1) / 100 = 300.00).

### Implementation Notes

- Ensure that the method handles the edge cases correctly.
- Be careful with the data types used, especially for the return value.
- The precision of the output is important; it must be exactly two decimal places.

Complete this lab by implementing the `calculateSimpleInterest`

method as per the above specifications. Test cases will verify the accuracy of your implementation, including the method signature, parameter handling, and the precision of the calculated interest.
