Do you know what is difference between the Scanner vs Buffered reader class? Have you ever thought what can be the possible differences between the Scanner vs Buffered reader class? Let us know some differences between Bufferedreader vs Scanner.
But before we start making differences between Bufferedreader vs Scanner, let us first know about them. This knowledge will help you to know Java Scanner vs Bufferedreader in a better manner.
Let us take a simple example from our daily life
Basically what humans do is, they can able to take input in two ways. One is known as the eating process. Another is known as the drinking process. When anybody is hungry, they will eat food. When anybody is thirsty, they will drink any liquid.
But for that, you need to know, in which process you need to provide which input. Suppose, you are hungry. Taking a lot of water will not help in such a case. In such cases, you need to take your food. Similarly, when you are thirsty, eating a lot of food will not help you. In that case, you need to drink any liquid.
So, how can you identify at which moment you need which type of input? As you know the processes in a good manner. You are familiar with hunger & thirst. You know what is difference between hunger & thirst.
The same thing goes for the Java Scanner vs Bufferedreader. Scanner vs Bufferedreader in Java helps you to find out the difference between the input-taking process. Scanner vs Bufferedreader in Java helps you to identify the method which will use in the particular case.
Before we go for the differences between Scanner vs Buffered reader class in Java, we need to first clear those things briefly. Let us know each of them one by one.
What Is Scanner In Java? Read Below
The Scanner is a particular class in Java. It is used to take the input in Java. While using the command line, the user can provide the input there. It is a widely used method in Java. many coders used this method in their programs as it is very easy to write. There are many methods are present in this class. For taking integer input, we cause the nextInt() method. For taking string input, we can use the nextLine() method. Similarly, there are many methods for each & every input.
The Scanner in Java program sometimes may create a problem. This is the problem that can lead to the differences between Scanner vs Buffered reader classes. In Scanner, the coder needs to be very sure which type of data is going to be taken. Suppose, the coder implemented code to accept the integer. But the use is providing the string value. So, there will be a problem in such cases.
What Is Bufferedreader In Java? Read Below
After knowing about the Scanner class in Java, it is a good practice to know about Bufferedreader class briefly. As it will help to understand the differences between the Scanner vs Buffered reader class. It is another type of class that helps to accept input from the user.
The user will provide the input to the command prompt. From there using this method, developers accept the value from the user.
It is something different from the Scanner class. In the Scanner class, there are many methods to take the inputs from the user. But in this case, the user can only provide the input in a single form. It is the string form. Users can provide any data like an integer.
But they will be treated as a string. Using some different methods, they can be converted to the desired input. So, the Bufferedreader method will not create those problems which were created by the Scanner class.
Before we move to the differences between the Scanner vs Buffered reader class, let us know the implementation process one by one briefly.
How To Do Implementation Of Scanner Class? Get To Know
Here, we have to first import the special package. This package will help you to use the Scanner class. We have to import java.util.Scanner package. Then we have to make the object of the class. Using that object we will take the input.
As here we are taking the integer input, we will use the nextInt() method.
Example:
import java.util.Scanner; // Scanner Package Importing
public class Main {
public static void main(String args[]){
Scanner zap = new Scanner(System.in); // Making Scanner Object
System.out.println("Enter An Integer: ");
int a = zap.nextInt(); // Using nextInt() Method To Take Integer Value
System.out.printf("Entered Value: " + a); // Display The Input Number
}}
Let us know the output of the above code. It will help you to understand the Scanner class implementation.
Output:
How To Do Implementation Of Bufferedreader Class? Get To Know
After knowing about the Scanner class, it is time to know about the implementation of Bufferedreader class. This will help you to understand the difference between the Scanner vs Buffered reader class.
Here, we need to import another important package which is java.io.*. Then we have to make an object for Bufferedreader class. As we will take the integer input, we need to convert the data to the integer by using the parseInt() method.
Example:
import java.io.*; // Important Package Importing
public class Main {
public static void main(String args[]) throws IOException{
BufferedReader zap = new BufferedReader(new InputStreamReader(System.in)); // Object
System.out.println("Enter An Integer Value");
int a = Integer.parseInt(zap.readLine()); // Accepting Integer Input
System.out.printf("Entered Input: " + a); // Printing The Input Value
}}
Let us know the output of the above code. It will help you to understand the Bufferedreader class implementation.
Output:
Now after knowing the implementation of the Scanner & Bufferedreader class, it is time to know the difference between the Scanner vs Buffered reader class.
What is the Difference Between Scanner Vs Buffered Reader Class?
Scanner Class |
Bufferedreader Class |
| The Scanner is asynchronous by its nature. | Bufferedreader class is synchronous by its nature. |
| Scanner class can only be used in the single-threaded environment. | Bufferedreader class can be used in multi-threading cases. |
| The Scanner is slower than the Bufferedreader class. | Bufferedreader is faster than the Scanner class. |
| It has a lower buffer memory than the Bufferedreader class. It has a buffer memory of nearly about 2kb. | Bufferedreader has higher buffer memory than the Scanner class. It has a buffer memory of nearly about 9kb. |
| There are many methods in the Scanner class. Like there are nextInt(), nextLine(), etc. | Bufferedreader has also many other methods, Like there is parseInt(), parseShort(), etc. |
Conclusion:
As we saw the difference between Scanner vs Buffered reader class is very important.
Bufferedreader vs Scanner helps the programmer to find the best input method. According to the choice, the programmer can choose anything between Scanner vs Bufferedreader in Java.
Java Scanner vs Bufferedreader will help you a lot in the future. It is used for developing a large application using Java.
