public void Countword (String str) {
string[] Wordsarray = Str.split ("");
map<string, integer> wordsmap = new hashmap<string, integer> ();
for (String Word:wordsarray) {

if (Wordsmap.containskey (word)) {
Wordsmap.put (Word, wordsmap.get (word) + 1);
} else {
Wordsmap.put (Word, 1);
}
}

set<string> Setkey = Wordsmap.keyset ();
iterator<string> Itkey = Setkey.iterator ();
while (Itkey.hasnext ()) {
String Word = Itkey.next (). toString ();
int count = Wordsmap.get (word);

System.out.println ("word" + word + "occurrences" + Count + "Times");

}
}

}

The JUnit test code is as follows:

Package com.liu.ST2;
