title: Converting Map<String,String> into json
body: <p>I have <code>Map&lt;String,String&gt;</code> in java like this : </p>
  
  <pre><code>{card_switch=Master, issuing_bank=ICCI, card_Type=DebitCard}
  </code></pre>
  
  <p>I'm using the <a href="http://code.google.com/p/json-simple/" rel="noreferrer">simple json parser</a> to parse this map into json object. </p>
  
  <p>I tried : </p>
  
  <pre><code>Object json = JSONValue.parse(entry.getKey());
  </code></pre>
  
  <p>But I get an error message : </p>
  
  <pre><code>Object json = JSONValue.parse(entry.getKey());
                        ^
  method JSONValue.parse(String) is not applicable
    (actual argument Map&lt;String,String&gt; cannot be converted to String by method invocation conversion)
  method JSONValue.parse(Reader) is not applicable
    (actual argument Map&lt;String,String&gt; cannot be converted to Reader by method invocation conversion)
  </code></pre>
  
  <p>Is that possible to convert <code>Map&lt;String,String&gt;</code> into json? </p>
