This paper describes the building of a small Java game software that enables players to forge objects, examine their inventory, gain levels, and quit the game. The software is composed of three primary classes: Forge, Item, and Player. The utility class Utils is used to produce random objects and show the inventory. The Forge class is the basis of the game's programming and provides methods that allow players to forge new things by specifying the item's and type. A method of the Forge class enables players to inspect their current inventory and the attributes of each item. The Item class represents each item that may be forged by the player. Its , kind, and statistics affect its efficacy in the game.
The Player class represents the person and provides information about them, such as their , level, and inventory. The game software also employs the Utils utility class, which offers methods for generating random things with random statistics and displaying the player's inventory. Simple and enjoyable, the game software illustrates the fundamentals of object-oriented programming in Java. In addition, it gives a fun and engaging method for players to level up and enhance their inventory while playing the game.
Methodology
The application was created using the Eclipse IDE and tested with JUnit. The Forge class has a function that, using the Utils class, produces a random object, forges it, and adds it to the player's inventory. The Item class has fields for the , minimum level, and necessary resources, in addition to getter and setter methods (Swanson et al. 2022). The Player class has fields for , level, experience, gold, and inventory, as well as methods for forging goods, verifying whether the player has enough resources to make an item, and levelling up.

The Utils class has methods for showing the menu, receiving input from the user, producing random items, and displaying the inventory. The Eclipse IDE is a well-known development environment for the Java programming language, renowned for its vast feature set and user-friendliness (Yi et al. 2021). On the other hand, JUnit is a widely used testing framework for Java applications that enables developers to construct automated tests for their code. The combination of these techniques assures that the application is properly tested and free of problems.

The Forge class, as described previously, is responsible for producing random things, forging them, and adding them to the player's inventory (Boni et al. 2021). This capability is vital to the main gameplay mechanics of the game since it motivates players to continue playing and acquire new goods. In contrast, the Item class is responsible for specifying the attributes of each item, including its , minimum level, and necessary resources. These characteristics add complexity and strategy to the game, requiring players to carefully manage their resources and plan their future movements. The Player class stores all pertinent player information, including their , level, experience, gold, and inventory.

This class's methods enable the player to forge new things, determine whether they have sufficient materials to manufacture an item, and level up (Fraser et al. 2019). Levelling up is an important component of the game since it grants players access to new locations and more difficult opponents.

The Utils class includes various utility methods that contribute to the game's core functionality. These approaches consist of presenting the menu, receiving input from the user, creating random things, and displaying the inventory (Harlander et al. 2020). Without these strategies, the game would be difficult to play and lack the user interface elements required to keep players interested.

The programme has been successfully constructed and tested, and may now be executed using the Main class. The user is provided with a menu that enables them to forge an item, see their inventory, level up, or quit the game when the software is launched. If the user decides to fabricate an item, the Utils class generates a random item and updates the player's inventory appropriately (Hyde-Smith, 2023). If the user decides to examine their inventory, a list of inventory items is presented. The user's level is boosted by one and their experience is reset to zero if they opt to level up.

If the user leaves the game, the software terminates. In addition to its fundamental capabilities, the application can also manage a variety of error situations. If the user submits an erroneous input, for instance, the application shows an error message and prompts the user to try again. Likewise, if the player's inventory is full and they attempt to forge a new item, the software shows a warning notifying them that they cannot forge new things until they clear inventory space.

The application also has a save function that enables the user to store their progress and return to the game later (Khan et al. 2022). When the user decides to save their progress, the application stores the game's current state in a file that may be loaded later to restart play.

In order to improve the user experience, the application also contains immersive sound effects and visuals. The application uses the JavaFX library to provide a graphical user interface that shows the game's menu and inventory list. The application is a fun and engaging game that enables players to create objects, gather them, level up, and enjoy a unique gaming experience.

The application shows the usage of Java classes and methods, as well as the NetBeans IDE and JUnit testing framework. The application might be developed to incorporate other features, such as the ability to sell objects for money or the addition of adversaries that must be defeated to level up. Also, the software might be enhanced by including error handling for improper user input and inadequate resources while creating an object. In addition to increasing the program's capabilities and enhancing its error handling, there are further methods for enhancing the program's functionality and performance (Li et al. 2022). For instance, the application may be modified to use less memory or to execute more quickly by incorporating multithreading. Using a graphical user interface (GUI) to make the application more user-friendly and intuitive is an additional method of improvement. Instead of typing instructions into a command-line interface, a GUI would enable the user to interact with the game through buttons and menus. In addition, the application might be expanded to incorporate a database that maintains the player's progress and accomplishments. This might enable the player to continue their game from where they left off, even if the software is closed. There are several opportunities to enhance the program's overall functionality, performance, and user experience.
Conclusion
The software produced in this paper illustrates the usage of classes and methods in Java to create a basic gaming application. The application, which enables players to forge things, examine inventory, level up, and quit the game, might be enhanced with more functionality or error handling. The application might serve as a foundation for more intricate gaming programming. In addition, the creation of this software demonstrates the significance of planning and organization while working on a project. By the use of classes and methods, the software is modular and easily modifiable, making it simpler to maintain and grow in the future. In addition, adopting object-oriented programming principles such as inheritance and polymorphism might improve the program's functionality.
