How to only read second word on each line Java

until now I have been reading in a file with BufferedReader line by line, however, now I would like to be able to only store the second word on that line. I have my line stored in a hashmap for easy lookup. int i=0; HashMap mapHash = new HashMap(); try { BufferedReader in = new BufferedReader(new FileReader("file")); String st; while ((st = in.readLine()) != null) { st = st.trim(); //store the lexicon with position in the hashmap mapHash.put(i, st); i++; } in.close(); } catch (IOException e) { } Could anyone help me out to only read the second word on each line? Thanks!
Use split?
