All values are with double quotes. Those values are "Fitness Head, Fiteness " Head and Fitness Head". I have to replace all double quotes with double double quotes using Java. What will be the java code to do that?

You don't need to replace double quotes anywhere if you are using JDBC to insert/fetch the values - this is all taken care of as long as you use PreparedStatements and placeholders.

See this tutorial.

Use String.replace

For example

String doubleQuotes = "\"Fitness head";
doubleQuotes.replace("\"", "\"\"");

Replacing single double quotes with double double quotes:

"abc\"def".replace("\"", "\"\"")

What about this:

String newValue = oldValue.replace("\"", "\"\"");
