public class UniqueUSER {

static HSSFWorkbook hwb=new HSSFWorkbook();

static HSSFSheet sheet = hwb.createSheet("new sheet");

public static void main(String[]args) throws IOException

{

HSSFRow row;

HashSet names = new HashSet<>();

BufferedReader br=new BufferedReader(new FileReader("simle.log"));

PrintStream out=new PrintStream("D:/Excel.xls");

String str=null;

int count=0;

while((str=br.readLine())!=null) {

if(str.contains("FLTR"))

{

String user=str.substring(97, 135);

count++;

names.add(user);

HSSFRow row1= sheet.createRow((short)count);

row1.createCell((short) 0).setCellValue("names");

}

}

Iterator itr=names.iterator();

while(itr.hasNext()) {

out.println(itr.next());  

}

}
