This can save you tons of time and can speed up your learning and testing. This feature can be enabled from a setting and then Eclipse will escape all double quotes, line breaks, new lines, or any other character which needs escaping automatically. The quickest and the best way I found is to leverage Eclipse's capability to Escape text when pasting into a string literal. How to Escape JSON String in Java Source Code using Eclipse You can even use text editors like Notepad++, EditPlus, or Sublime (See my Java tools) which supports regex searching to replace all double quotes with escape characters before copying the String literal into Java code, but this is again error-prone if your JSON string contains line breaks and new line because of those needs to escaped manually. you can save that String in a file and then read the file in your program instead of copy-pasting String into your Java code, or, you can directly download from the internet by using HttpConnection utility of Apache Commons, though this required additional dependency in your Java application and may slow down your testing. So If you have a JSON String which you need to parse in Java using Jackson, what will you do?

" can be escaped as \" if it occurs inside String itself. You can escape String in Java by putting a backslash in double quotes e.g. If you remember, if your String contains double quotes then those need to be escaped when you are pasting them as String literals in your Java code.

This is the quickest way to test and learn parsing JSON string in Java, but the main problem with this approach is that the JSON String also includes double quotes "" which is also used for enclosing String literals in Java. a RESTful web service and then use the Jackson library to parse the JSON.
