Try this. This give for last 5 line.

 public static void main(String[] args) throws IOException {
            List list =new ArrayList();
            FileInputStream in = new FileInputStream("C:/adminconsole.txt");
            BufferedReader br = new BufferedReader(new InputStreamReader(in));

            String strLine ="", tmp;
            while ((tmp = br.readLine()) != null){ 
                //strLine =tmp+"\n"+strLine;
                list.add(tmp);
                }

            if(list.size()>5){
                for (int i=list.size()-1; i>=(list.size()-5); i--) {
                    System.out.println(list.get(i));
                }
            }else{
                for (int i=0; i<5; i++) {
            System.out.println(list.get(i));
        }

            }

        }
