What type of variable is most suitable for storing results in the system?

To store results in a Java system, types that correspond to the nature of the result are usually used:

• If the result is a numeric value (e.g., score, quantity), primitive types like int, double, etc., are suitable.
• If the result is a boolean value (success/failure), boolean is used.
• If the result is a complex object with multiple fields, a separate class with the necessary fields is created.

For example, if you need to store the result of an operation with a code and a message, you can create a class:

public class Result {
    private boolean success;
    private String message;

    public Result(boolean success, String message) {
        this.success = success;
        this.message = message;
    }

    // getters and setters
}

Thus, the choice of type depends on what exactly needs to be stored and how the result will be used.
