title: Parsing JSON Object in Salesforce Apex
body: <p>How do I parse a jsonObject which is in a given format in Apex?</p>
  
  <p>I need List&lt;String> from the items array which contains the id attribute. What is some appropriate method?</p>
  
  <p>For parsing it, I try to create a class with code:</p>
  
  <pre><code>public class JSON2Apex {
  
      public class Items {
          public String kind;
          public String etag;
          public String id;
          public String status;
          public String htmlLink;
          public String created;
          public String updated;
          public String summary;
          public String description;
          public String location;
          public Creator creator;
          public Creator organizer;
          public Start start;
          public Start end;
          public String iCalUID;
          public Integer sequence;
          public Reminders reminders;
      }
  
      public class Reminders {
          public Boolean useDefault;
      }
  
      public class Start {
          public String dateTime;
      }
  
      public class Creator {
          public String email;
          public String displayName;
          public Boolean self;
      }
  
      public String kind;
      public String etag;
      public String summary;
      public String updated;
      public String timeZone;
      public String accessRole;
      public List&lt;DefaultReminders&gt; defaultReminders;
      public List&lt;Items&gt; items;
  
      public class DefaultReminders {
          public String method;
          public Integer minutes;
      }
  
  }
  </code></pre>
  
  <p>But in this class it is showing some reserved keyword is user like end , dateTime etc so can't proceed further with this approach.</p>
