Another Example of reading data from keyboard by InputStreamReader and BufferdReader class until the user writes stop

Reading data from keyboard:

There are many ways to read data from the keyboard. For example:

• InputStreamReader
• Console
• Scanner
• DataInputStream etc.

InputStreamReader class:

InputStreamReader class can be used to read data from keyboard.It performs two tasks:

• connects to input stream of keyboard
• converts the byte-oriented stream into character-oriented stream

BufferedReader class:

BufferedReader class can be used to read data line by line by readLine() method.

Example of reading data from keyboard by InputStreamReader and BufferdReader class:

In this example, we are connecting the BufferedReader stream with the InputStreamReader stream for reading the line by line data from the keyboard.

1. //<b><i>Program of reading data</i></b>  
2.   
3. import java.io.*;  
4. class G5{  
5. public static void main(String args[])throws Exception{  
6.   
7. InputStreamReader r=new InputStreamReader(System.in);  
8. BufferedReader br=new BufferedReader(r);  
9.   
10. System.out.println("Enter your name");  
11. String name=br.readLine();  
12. System.out.println("Welcome "+name);  
13.  }  
14. }  

Output:Enter your name
       Amit
       Welcome Amit

In this example, we are reading and printing the data until the user prints stop.

1. import java.io.*;  
2. class G5{  
3. public static void main(String args[])throws Exception{  
4.   
5.  InputStreamReader r=new InputStreamReader(System.in);  
6.  BufferedReader br=new BufferedReader(r);  
7.   
8.  String name="";  
9.   
10.   while(name.equals("stop")){  
11.    System.out.println("Enter data: ");  
12.    name=br.readLine();  
13.    System.out.println("data is: "+name);  
14.   }  
15.   
16.  br.close();  
17.  r.close();  
18.  }  
19. }  

Output:Enter data: Amit
       data is: Amit
       Enter data: 10
       data is: 10
       Enter data: stop
       data is: stop
