How to write JSON string value in code?

I want to store the following string in a String variable

{"Id":"123","DateOfRegistration":"2012-10-21T00:00:00+05:30","Status":0}

This is the code I use ..

String str="{"Id":"123","DateOfRegistration":"2012-10-21T00:00:00+05:30","Status":0}";

.. but it's showing error ..

Solution

You have to do this

String str="{\"Id\":\"123\",\"DateOfRegistration\":\"2012-10-21T00:00:00+05:30\",\"Status\":0}";
