Hi Friend,

Try the following code:

import java.io.*;
import java.util.*;

public class ReadFile{
    public static void main(String[] args) throws IOException{
      Scanner input=new Scanner(System.in);
      System.out.println("Enter File Name with path: ");
      String st=input.next();
      File f=new File(st);

      if(!f.exists()&& f.length()<0)
      System.out.println("The specified file does not exist");

      else{
         FileInputStream finp=new FileInputStream(f);
      byte b;
    do{
      b=(byte)finp.read();
      System.out.print((char)b);
    }
      while(b!=-1);
        finp.close();
        }
    }
  }

Thanks
