Answer 1

but still by removing quotes i am not getting out put here is modified code
import java.io.*;
class read
public static void main(String args[]) throws IOException
     String line;
     String[] full=new String[10];
     int count=0;
     FileInputStream fis=new FileInputStream("sampledocument.txt");
     DataInputStream input= new DataInputStream(fis);
     while((line= input.readLine())!=null)
          System.out.println("line");
          count++;
          full[count]=line;
it creates out put on single line as "line " where as in original text i have written i mean to say in text file
when going gets tough ,ough gets going.
