this had tried before posting question here..but doesn't seem work. can me out..?

you should write java program.

here's may started (rough code):

bufferedreader br = new bufferedreader(new filereader(file));  //start reading file line-by-line while ((line = br.readline()) != null) {      //replace * whatever want     // use counter keep track of lines give corresponding line number     string val = line.replace("*",countervar.tostring());  } br.close(); 

write file using bufferedwriter again, wrap printwriter if wish to,

printwriter out = new printwriter(new bufferedwriter(new filewriter("outputfile")));
