第一题

实现代码如下：

package com.liu.ST2;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class Question1 {

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("单词 " + word + " 出现" + count + "次");

}
}

}

Junit测试代码如下：

package com.liu.ST2;

import static org.junit.Assert.*;

import org.junit.Test;

public class Q1TestTest {
@Test
public void testCountWord() {
Question1 q1 = new Question1();
q1.countWord("Hello World My First Unit Test Test");
}

}

Junit测试及ElcEmma覆盖率如下：
