Replace string containing " with \"?

Question

How can I replace string containing " with \" ?

replace(""","\"") is not working for me.

public static String replaceSpecialCharsForJson(String str){
    return str.replace("'","\'")
              .replace(":","\\:")
              .replace("\"","\"")
              .replace("\r", "\\r")
              .replace("\n", "\\n");
} 

Answer 1

You can try with:

replace("\"","\\\"")

Since both " and \ are metacharacters, you have to escape them with \
