Could anyone please tell me why am I getting this error message

c.java:15: cannot resolve symbol
symbol : method readLine ()
location: class java.io.BufferedInputStream
while((line = br.readLine()) != null)

Thanks

What kind of object is br? Does that object have a readLine() method?

And I think your line of code should read:
while((line==br.readLine())!=null)

because a single = is only used for assigning values AFAIK.

This is my code
===============

public void insertline() throws java.io.IOException
{
           File inp=new File("output.txt");
           FileInputStream fr = new FileInputStream(inp);
           BufferedInputStream br=new BufferedInputStream(fr);
           boolean flag=true;
    while((line = br.readLine()) != null)
           {
               int present=line.indexOf(STRING_TO_REPLACE);
               if(present==0)
               {
                   flag=false;
               }
           }
           br.close();
           if(flag)
           {
               lineInsertion("output.txt");
           }
}

A single = is fine, because I am assigning values
while((line==br.readLine())!=null)

Thanks

BufferedInputStream doesn't have readLine()

Replace the BufferedInputStream with a BufferedReader:

Code:

BufferedReader br = new BufferedReader(new InputStreamReader(fr));

Thanks a lot, that really helped.
