My code tries to replace "," with "/" in a string. Should I escape "," in the regex string? Both of the two code snippets generated the same results, so I am confused.
Code snippet 1:
String test = "a,bc,def";
System.out.println(test.replaceAll("\\,", "/"));
Code snippet 2:
String test = "a,bc,def";
System.out.println(test.replaceAll(",", "/"));
Should I use "," or "\,"? Which is safer?
Thanks.
