Q:

Write a program to fix the error being produced by the Infinite file?

Answer

- The infinite file error can be solved when the data will be read continuously from the file. 


- The error can be solved by using the keys that provide only the resources that are required. 


- The following program is as follows:


osw.write ("HTTP/1.0 200 OK\n\n"); 


while (c != -1) { 


sb.append((char)c); 


c = fr.read(); 



osw.write (sb.toString()); 


- This converts the requested file in such a way that if the file exists it shows the messages as ok otherwise it shows an error.


- Limited file access is to be given to the file to remove the error from the infinite file type.
