io.codemodder.codemods.SubstituteReplaceAllCodemod.description.md Maven / Gradle / Ivy

This change replaces `String#replaceAll()` with `String#replace()` to enhance performance and avoid confusion.

The `String#replaceAll()` call takes a regular expression for the first argument, which is then compiled and used to replace string subsections. However, the argument being passed to it doesn't actually appear to be a regular expression. Therefore, the `replace()` [API](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#replace-java.lang.CharSequence-java.lang.CharSequence-) appears to be a better fit.

Our changes look something like this:

```diff
    String init = "my string\n";

-   String changed = init.replaceAll("\n", "
");
+   String changed = init.replace("\n", "
");
```
