title: How to override = symbol while converting HashMap to String using toString method?
body: <p>Below is part of code where map is initialized as:<br>
  <code>Map&lt;Integer,Integer&gt; map = new HashMap&lt;&gt;();</code><br>
  and the line which I want to modify the output is<br></p>
  
  <p><code>System.out.println("Price and items "+map.toString());</code>
  <br>where the output presently is
  <br> <strong>{100=10,200=5}</strong></p>
  
  <p>I want to display<br>
  <strong>{100:10,200:5}</strong></p>
