In the world of software development, it is essential to have efficient and reliable methods for handling status flags and messages. These components play a crucial role in the communication between different parts of a program and help in identifying and resolving errors. In this article, we will explore an efficient method for returning status flag and message in Java.
Before diving into the details, let's first understand what exactly are status flags and messages. In simple terms, a status flag is a variable that is used to indicate the current state of a program or a particular process. It can have different values such as "success", "failure", "in progress", etc. On the other hand, a message is a string that provides information about the status flag and helps in understanding the cause of a particular state.
Now, let's get back to our main topic, which is the efficient method for returning status flag and message in Java. The method we will be discussing here is called the "Wrapper Class Method". This method involves creating a wrapper class that contains two variables - one for the status flag and the other for the message. Let's see how this method works in detail.
Step 1: Create a Wrapper Class
The first step is to create a wrapper class that will hold the status flag and the message. Let's name this class "StatusWrapper". We will define two private variables - "status" and "message" of type String and provide appropriate getters and setters.
Step 2: Set the Status and Message
Next, we need to set the values for the status and message variables. The best way to do this is by creating a constructor that takes in these values as parameters. This way, we can initialize the values while creating an object of the StatusWrapper class.
Step 3: Return the Wrapper Object
The final step is to return an object of the StatusWrapper class with the status and message values set. We can do this by creating a method that takes in the status and message values as parameters, creates an object of the StatusWrapper class, and sets the values using the setters. This method will then return the object.
Let's take a look at the code for better understanding:
```
public class StatusWrapper {
private String status;
private String message;
// Constructor
public StatusWrapper(String status, String message) {
this.status = status;
this.message = message;
}
// Getters and setters
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
// Method for returning the wrapper object
public static StatusWrapper getWrapper(String status, String message) {
StatusWrapper wrapper = new StatusWrapper(status, message);
return wrapper;
}
}
```
Now, let's see how this method can be used in a Java program:
```
// Calling the getWrapper method and passing in the status and message values
