How to convert String format 1.203.45 to string format 1203.45. Tried to implement regular expressions, but nothing works. Java.

CodePudding user response：

You could use a regex replacement which removes all dots save the last one:

String input = "1.203.45";
String output = input.replaceAll("\\.(?=.*\\.)", "");
System.out.println(output);  \\ 1203.45
