Something along these lines:

• Create a HashMap<String, Integer>
• For each line in your input:
  • Split it into the word and number, and parse the number part (as Matthew comments below, using Scanner can help with this part)
  • See if there's anything in your map for that word
    • If there isn't, use map.put(word, value)
    • If there is, compare the current value with the new one, and replace the current value if the new one is higher
• When you've read everything in the file, your map will contain (word / maximum value) pairs. You can iterate over the map's entries to get at everything you need.
