Java Text Reader

I want to make a program that read the inputed text and parse every word and store it in a data structure, so i can later have some statistics about that (frequency of words, most common word etc).

I need guidance about two things:

a. best approach for my "parse function", which will divide the text in terms

b. best approach for 开发者_Go百科data structure choice, in what concerns complexity, access times and best suitable for the case.

a) best approach for my "parse function"

Use a Scanner it has nice functions for next (word) etc.

b) best approach for datastruture choice

A map from word to a statistics object: Map<String, WordStatistics>.

Depending on the other stats you need, it sounds like you want to use a Map<String, Integer>. Then for each key (the word you read in) you can store how many times you read it in. The rest sounds like homework...
