Can't get tests to pass for the GeeCON comp programming challenge

[adam den]

I have written a very simple peace of code for this post.
Could anyone please let me know why it is failing as per the output of this test harness?

import java.util.Arrays;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;

public class GeeConComp {

    public static Map<String, Integer> wordOccurrence(String sentence) {
    	Map<String,Integer> wordMap = new HashMap<String,Integer> (); 
    	List<String> wordList = Arrays.asList(sentence.toLowerCase().split("\\s"));
    	Set<String> wordSet = new HashSet<String>(wordList);
    	for(String word : wordSet){
    		int wc = 0;
    	for(String actualWrd : wordList){
    		if(word.equalsIgnoreCase(actualWrd)){
    			wc++;	
    		}
    		
    	}
    	wordMap.put(word, wc);
    	}
    	System.out.println(wordMap);
        return null;
    }

    public static void main(String[] args) {
        System.out.println("CodeRanch GeeCON Prague 2014 competition");
        System.out.println("========================================");
        String sentence1 = "I really REALLY love CodeRanch";
        Map<String, Integer> expectedWordOccurrence1 = new HashMap<>();
        expectedWordOccurrence1.put("i", 1);
        expectedWordOccurrence1.put("really", 2);
        expectedWordOccurrence1.put("love", 1);
        expectedWordOccurrence1.put("coderanch", 1);
        assertOccurrences(expectedWordOccurrence1, wordOccurrence(sentence1));

        String sentence2 = "Good better best may I never rest until my good is better and my better best";
        Map<String, Integer> expectedWordOccurrence2 = new HashMap<>();
        expectedWordOccurrence2.put("good", 2);
        expectedWordOccurrence2.put("better", 3);
        expectedWordOccurrence2.put("best", 2);
        expectedWordOccurrence2.put("may", 1);
        expectedWordOccurrence2.put("i", 1);
        expectedWordOccurrence2.put("never", 1);
        expectedWordOccurrence2.put("rest", 1);
        expectedWordOccurrence2.put("until", 1);
        expectedWordOccurrence2.put("my", 2);
        expectedWordOccurrence2.put("is", 1);
        expectedWordOccurrence2.put("and", 1);
        assertOccurrences(expectedWordOccurrence2, wordOccurrence(sentence2));
    }

    private static void assertOccurrences(Map<String, Integer> expected, Map<String, Integer> actual) {
        if (expected.equals(actual)) {
            System.out.println("Test PASS :)");
        } else {
            System.out.println("Test FAIL :(");
            System.out.println("Expected: " + expected);
            System.out.println("Actual  : " + actual);
        }
    }
}

OUTPUT
+++++++

CodeRanch GeeCON Prague 2014 competition
========================================
{love=1, really=2, coderanch=1, i=1}
Test FAIL
Expected: {love=1, really=2, coderanch=1, i=1}
Actual : null
{never=1, may=1, is=1, better=3, best=2, good=2, rest=1, my=2, until=1, i=1, and=1}
Test FAIL
Expected: {is=1, never=1, may=1, better=3, best=2, good=2, rest=1, my=2, until=1, and=1, i=1}
Actual : null

Hello adam, welcome to the Ranch

I moved your question out of the main competition thread so we could have some discussion about it on the side. Once you have it working and are happy with it then you are more than welcome to submit your new solution to the competition thread again.

Now, back to your question:
You are so very close. Observe that the tests are inspecting the data being returned from the wordOccurrence method, they are not inspecting what is being output with System.out.println. So have a think about what you need to do with wordMap at the end of the method.

[adam den]

oh, sorry for so silly mistake!!!

wordOccurrence method should return wordMap;

[Campbell Ritchie]

Welcome again

I presume you will be submitting your corrected version.

[adam den]

thank you!!!
Regarding posting correct version, i don't think I could win it as per preconditions otherwise i could have tried for it

[Tim Cooke]

But by not entering at all you are guaranteeing you won't win. What have you got to lose?

Remember, you can enter more than once if you want to.
