title: confusion about Map.containsValue method
body: <p>I have a following program where I have a hashmap. The keys of the hashmap are simple integers and the values are integer arrays. The program is as follows:</p>
  
  <pre><code>Map&lt;String , int []&gt; myMap = new HashMap&lt;String , int []&gt;();
  
   myMap.put("EvenNumbers", new int[]{2,4,6,8,10,12,14,16,18,20});
   myMap.put("OddNumbers", new int[]{1,3,5,7,9,11,13,15,17,19});
   myMap.put("DivisibleByThree", new int[]{3,6,9,12,15,18});
   myMap.put("DivisibleByFive", new int[]{5,10,15,20});
  
   int[] array = new int[]{1,3,5,7,9,11,13,15,17,19};
  
   System.out.println(myMap.containsKey("EvenNumbers"));
   System.out.println(myMap.containsKey("OddNumbers"));
  
   //The following two lines produce a false output. Why ?         
   System.out.println(myMap.containsValue(new int[]{5,20,15,20} ));
   System.out.println(myMap.containsValue(array));
  </code></pre>
  
  <p>while the following code produces a true value</p>
  
  <pre><code> HashMap newmap = new HashMap();
  
        // populate hash map
        newmap.put(1, "tutorials");
        newmap.put(2, "point");
        newmap.put(3, "is best"); 
  
        // check existence of value 'point'
        System.out.println("Check if value 'point' exists: " + 
        newmap.containsValue("point"));
  </code></pre>
  
  <p>Why is this so ? Where have I gone wrong? what is the caoncept that I am missing? I feel that I am doing the same thing in both the cases. I am new to the java environment , hence the confusion. Please help me clear the concepts.</p>
