String replaceAll("¾") in java
java, regex, replaceall, string
Solution
You're using `replaceAll()`, which takes a regular expression. In regex-land, `.` means "any character". Use `replace()` instead, which works with literal strings.
Problem
I have really weird error in my java code and can not figure out what is wrong. Let's say I have this code: ``` private void test() { String test1 = replace("1.25"); String test2 = replace("1.5"); String test3 = replace("1.75"); } private String replace(String s) { s = s.replaceAll(".25", "¼"); s = s.replaceAll(".5", "½"); s = s.replaceAll(".75", "¾"); return s; } ``` Then the result will be: test1 = "¼" test2 = "½" test3 = "½" ?????????? Can someone please explain why test3 becomes "½"?
