Skip the empty line while processing

Question

Hi all
i'm reading from a file and i want to skip the empty line and process the line which has some data, but it seem that i doesnot process the "\n"as an empty line
for example i have the following data
i went to school
(empty line)
5 days a week
(empty line)
and i have the following code
    while((line = in.readLine() ) !=null) 
             if(line!="\n")
                  codes=line.split("   ");
                  }//if else
                  else
                  //do nothing
                  }

may i ask another question
i have a file which has several sentences but the spaces between these sentences are not unique i.e some time 3 empty lines some times more or less
i have a code to make all the spaces just 1 between any sentece but it work with system.out.print but not with files any ideas
here is the code
        StringBuffer buffer=new StringBuffer();
        try{
            BufferedReader read=new BufferedReader(new FileReader(fname));
BufferedWriter br = new BufferedWriter(new FileWriter("111.txt"));
            String line=read.readLine();   
            boolean isNewLine=false;
            while(line!=null){
                if(line.length()==0 && !isNewLine){
                    buffer.append("\n\n");
                                   isNewLine=true;
                }//if
                else if(line.length()!=0){
                    buffer.append(line);
                    System.out.println("in ELSE");
                    isNewLine=false;
                }//else
                line=read.readLine();
            }//while
            br.write(buffer.toString());
             read.close();
       br.close();
        }//try
        catch(IOException ioe){
            ioe.printStackTrace();
        }
