How can I add escape characters to a Java String?

Question

If I had a string variable:

String example = \"Hello, I\'m here\";

and I wanted to add an escape character in front of every \'

Try Apache Commons Text library-

    System.out.println(StringEscapeUtils.escapeCsv("a\","));
    System.out.println(StringEscapeUtils.escapeJson("a\","));
    System.out.println(StringEscapeUtils.escapeEcmaScript("Hello, I'm \"here"));

Result:

"a"","
a\",
Hello, I\'m \"here
