Cleaning Robot Manager (JavaBasics_Task_172_V0.1)

📖 Description

This project demonstrates the usage of the finally block in Java. In software development, certain actions (like closing a database connection or sending a final status report) must occur regardless of whether an error occurred. This simulation uses a cleaning robot to show how the finally block guarantees execution of completion messages.

📋 Requirements Compliance

• Task: Divide 10 tasks by 2 tasks per minute to calculate duration.
• Mechanism: Implement a try-finally structure.
• Guarantee: Use the finally block to ensure the robot always reports its status.
• Goal: Display the calculation result and the mandatory final status message.

🚀 Architectural Stack

• Java 8+

🏗️ Implementation Details

The finally block follows a try or catch block. Its primary characteristic is that it always executes, even if an exception is thrown or a return statement is encountered. This makes it the ideal place for cleanup logic or mandatory logging, ensuring system reliability.

📋 Expected result

Cleaning time: 5 minutes
Robot has finished its work. Execution completed.

💻 Code Example

Project Structure:

src/com/yurii/pavlenko/
                └── Solution.java

Code

package com.yurii.pavlenko;

public class Solution {
    public static void main(String[] args) {
        try {
            int totalTasks = 10;
            int tasksPerMinute = 2;
            int duration = totalTasks / tasksPerMinute;

            System.out.println("Cleaning time: " + duration + " minutes");

        } finally {
            System.out.println("Robot has finished its work. Execution completed.");
        }
    }
}
