Software Testing the second job-write a Java program that parses the frequency of occurrences of each word in a string and displays the word and the frequency at which it appears.

Topic One:

1. Write a Java program that parses the frequency of occurrences of each word in a string and displays the word and the frequency at which it appears. (the words are separated by a space, such as "Hello World My First Unit Test");

2. Write unit tests for testing;

3. Use Elcemma to view code coverage, which requires coverage of up to 100%.

Demo class:

1 ImportJava.util.HashMap;2 ImportJava.util.Iterator;3 ImportJava.util.Map;4 ImportJava.util.Set;5 6  Public classDemo {7 8      Public voidCountword (String str) {9string[] Wordsarray = Str.split ("");Tenmap<string, integer> wordsmap =NewHashmap<string, integer>(); One          for(String word:wordsarray) { A  -             if(Wordsmap.containskey (Word)) { -Wordsmap.put (Word, wordsmap.get (word) + 1); the}Else { -Wordsmap.put (Word, 1); -             } -         } +  -Set<string> Setkey =Wordsmap.keyset (); +Iterator<string> Itkey =setkey.iterator (); A          while(Itkey.hasnext ()) { atString Word =Itkey.next (). toString (); -             intCount =wordsmap.get (word); -  -System.out.println ("word" + word + "occurrences" + Count + "times"); -  -         } in     } -  to}
