Write a complete Java program in a source file named Assignment1.java that calculates the number of fully filled jars needed for storing milk, based on user input of gallons of milk, with appropriate comments, constants, and correct computation.

The program should include:

• A header comment block with your name, assignment description, and other details.
• A prompt asking the user for the gallons of milk.
• Calculation of the number of jars needed, assuming each jar can hold a fixed maximum volume.
• Use of constants for parameters like jar capacity.
• Display of the number of jars needed with the gallons entered.

Effective management of resources, such as milk storage, is critical in agricultural operations. Developing Java programs to assist farmers in planning their logistics combines computational efficiency with user-centered design. This paper discusses the process of creating a Java application that calculates the number of jars needed to store a given amount of milk, emphasizing best practices in coding, user input handling, and program structure.

First, the program begins with a comprehensive header comment block. This block includes the programmer's name, assignment title, and pertinent information such as course details and date. Proper documentation is essential for maintaining code, facilitating collaboration, and ensuring clarity for future modifications.

The core logic involves prompting the user for the total gallons of milk using the Scanner class. Input validation assumes the user provides a positive number or zero, which aligns with the problem constraints. The program then employs constants to define the maximum capacity of each jar, promoting readability and ease of maintenance. For example, setting the jar capacity as a constant allows for quick adjustments and prevents "magic numbers" within the code.

To compute the number of jars required, the program divides the total gallons by the jar capacity. Because partial jars are not feasible, the program rounds this value upward, ensuring that all milk is stored without loss. This can be efficiently achieved using the ceiling function from the Math class, which handles fractional parts correctly. For example, if the division results in 6.8, the program will determine that 7 jars are necessary.

The code then outputs a message indicating the number of jars needed for the given gallons of milk, providing clear feedback to the user. The program’s design emphasizes simplicity and clarity, facilitating ease of use in real-world scenarios.

In addition to implementing the core functionality, attention is paid to code readability, including appropriate variable naming and modular structure. Although the solution is contained within a single main method, the use of constants and comments improves maintainability.

Finally, thorough testing should confirm that the program correctly computes the number of jars for various inputs, including zero, small, and large values of gallons. For example, inputting 5 gallons results in 7 jars, while 6.8 gallons require 9 jars, demonstrating correct rounding and calculation.

In conclusion, this Java program exemplifies best practices in resource calculation applications, combining user interaction, constants utilization, and precise computation. Such programs can be extended for broader logistics planning tasks within the agricultural industry, promoting efficiency and effective resource management.
