Method bodies should generally not call
`java.util.regex.Pattern#compile(String)` with constant arguments. Instead,
define a constant to store that Pattern. This can avoid recompilation of the
regex every time the method is invoked.
That is, prefer this:
```java
private static final Pattern REGEX_PATTERN = Pattern.compile("a+");
public static boolean doSomething(String input) {
Matcher matcher = REGEX_PATTERN.matcher(input);
if (matcher.matches()) {
...
}
}
```
to this:
```java
public static boolean doSomething(String input) {
Matcher matcher = Pattern.compile("a+").matcher(input);
if (matcher.matches()) {
...
}
}
```
