[Q#18471500][A#18471715] How can I add escape characters to a Java String?

https://stackoverflow.com/q/18471500

If I had a string variable: and I wanted to add an escape character in front of every ' and " within the variable (i.e. not actually escape the characters), how would I do that?

I'm not claiming elegance here, but i think it does what you want it to do (please correct me if I'm mistaken): outputs

APIzation

public static void main(String[] args)
{
    String example = "Hello, I'm\" here";
    example = example.replaceAll("'", "\\\\'");
    example = example.replaceAll("\"", "\\\\\"");
    System.out.println(example);
}
Hello, I\'m\" here

package com.stackoverflow.api;

public class Human18471715 {

  public static String addEscapeCharacters(String example) {
    //    String example = "Hello, I'm\" here";
    example = example.replaceAll("'", "\\\\'");
    example = example.replaceAll("\"", "\\\\\"");
    return example;
  }
}
