How to Store User Input in a Specific Library Using Java Store Class

In the world of Java programming, one common challenge that beginners encounter is the proper organization and usage of libraries, especially when it comes to storing user input. If you're a newcomer to Java and struggling to grasp how to effectively store data in a specific library, you’re not alone! In this post, we'll explore a succinct way to achieve that using a simple example.

The Problem

You have created a Store class within a library and wish to use it to accept and store user input in your main application. Here's a breakdown of your requirement:

You want to store user inputs (like name and age).

You prefer not to use static variables for storage.

You may want to handle inputs based on user choices.

Let's take a look at the current structure of your code to understand where you might be going wrong.

Your Current Code Structure

You have two significant components in your code: the main application and the library containing the Store class.

Main Application (Test Class)

Library (Store Class)

The Solution

To successfully store user inputs without using static variables in your Store class, you should create an instance of the Store class in your main application. Let’s see how you can modify your code accordingly.

Step 1: Create an Instance of the Store Class

Instead of accessing the name and age directly from the Store class, you should create an object of Store and modify its properties based on user input.

Here’s how the modified code will look:

Step 2: Explanation of Changes

Creating a New Store Object: By instantiating a Store object (store), you can now store user inputs in that instance.

Switch Case Logic: The switch logic remains the same — it checks the user’s choice and assigns the input value to either the name or age field of the store object.

Additional Tip

Always remember to import your library properly in the main application to avoid any compilation errors. In the example above, we correctly imported the Store class using:

Conclusion

Storing user data in a specific library in Java doesn’t have to be complicated. With the right approach, using instances of your classes rather than static variables will allow your application to manage data effectively and in a more object-oriented manner.

Feel free to adapt this code further based on your application’s needs and remember, practice makes perfect in the world of programming!
