String replace with Java

Question

I currently have a string that contains the characters A, B and C, for example, the string looks like

"A some other random stuff B C"

other random stuff does not contain A, B or CI that want to replace A, B and C with "A", "B" and "C" respectively, which is the best way to do this at the moment I'm doing

String.replace("A", "'A'").replace("B", "'B'").replace("C", "'C'")

Answer 1

Answer to

cletus works great if A, B and C are exact single characters, but not if they can be long strings, and you just call them A, B and C, for example, for purposes. If they are longer than the lines, you need to do:

String input = "FOO some other random stuff BAR BAZ";
String output = input.replaceAll("FOO|BAR|BAZ", "'$0'");

- FOO, BAR BAZ, .

Answer 2

:

String input = "A some other random stuff B C";
String output = input.replaceAll("[ABC]", "'$0'");

:

'A' some other random stuff 'B' 'C'
