BufferedReader read code example

Example 1: java read file bufferedreader

try {
	File file = new File("data.txt");
	BufferedReader reader = new BufferedReader(new FileReader(file));
	String line;

	while((line = reader.readLine()) != null) {
	 	 System.out.println(line);
	}
} catch(IOException e) {
  	e.printStackTrace();
}

Example 2: bufferedreader java

import java.io.BufferedReader;
//
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
System.out.println(reader.readLine());

Example 3: BufferredReader Class

package com.javatpoint;  
import java.io.*;  
public class BufferedReaderExample {  
    public static void main(String args[])throws Exception{    
          FileReader fr=new FileReader("D:\\testout.txt");    
          BufferedReader br=new BufferedReader(fr);    
  
          int i;    
          while((i=br.read())!=-1){  
          System.out.print((char)i);  
          }  
          br.close();    
          fr.close();    
    }    
}

Example 4: BufferredReader Class

package com.javatpoint;  
import java.io.*;  
public class BufferedReaderExample{    
public static void main(String args[])throws Exception{             
    InputStreamReader r=new InputStreamReader(System.in);    
    BufferedReader br=new BufferedReader(r);            
    System.out.println("Enter your name");    
    String name=br.readLine();    
    System.out.println("Welcome "+name);    
}    
}

        st = new StringTokenizer(br.readLine().trim());
    }
    return st.nextToken();
