Replace all double quotes within String

Question

I am retrieving data from a database, where the field contains a String with HTML data. I want to replace all of the double quotes such that it can be used for parseJS

Answer 1

Here's how

String details = "Hello \"world\"!";
details = details.replace("\"","\\\"");
System.out.println(details);               // Hello \"world\"!

Note that strings are immutable, thus it is not sufficient to simply do details.replace("\"","\\\""). You must reassign the variable details to the resulting string.

Using

details = details.replaceAll("\"","&quote;");

instead, results in

Hello &quote;world&quote;!

Answer 2

String info = "Hello \"world\"!";
info = info.replace("\"", "\\\"");

String info1 = "Hello "world!";
info1 = info1.replace('"', '\"').replace("\"", "\\\"");

For the 2nd field info1, 1st replace double quotes with an escape character.
