You should first replace " with " and then replace "" with ". You can do it by chaining a few String#replaceAll() calls: which will produce

text = text.replaceAll("\\\"","\"").replaceAll("\"\"", "\"");
System.out.println(text);
"fullName":"Some full name"

public class Human33261057 {

  public static String escapeDoubleQuotes(String text) {
    text = text.replaceAll("\\\"", "\"").replaceAll("\"\"", "\"");
    return text;
  }
}
