Remove trailing zero in Java

Question

I have Strings (from DB), which may contain numeric values. If it contains numeric values, I'd like to remove trailing zeros such as: - `10.0000` - `10.234000` `str.replaceAll("\.0*$", "")`, works on the first one, but not the second one. A lot of the answers point to use `BigDecimal`, but the `String` I get may not be numeric. So I think a better solution probably is through the Regex.

Accepted Answer

there are possibilities:

```
1000    -> 1000
10.000  -> 10 (without point in result)
10.0100 -> 10.01 
10.1234 -> 10.1234
```

I am lazy and stupid, just

```
s = s.indexOf(".") < 0 ? s : s.replaceAll("0*$", "").replaceAll("\.$", "");
```

Same solution using `contains` instead of `indexOf` as mentioned in some of the comments for easy understanding

```
 s = s.contains(".") ? s.replaceAll("0*$","").replaceAll("\.$","") : s
```
