If we repeatedly call String#replaceAll, we internally repeatedly call the regular expression pattern compilation every time as following:
```java
public String replaceAll(String regex, String replacement) {
return Pattern.compile(regex).matcher(this).replaceAll(replacement);
}
```
The modifications are to keep the compiled pattern.
Therefore, compiling a relatively expensive regular expression pattern does not have to be done every time.
