class LocalDate {
public String toString() {
if (absYear < 1000) {
if (yearValue < 0) {
buf.append(yearValue - 10000).deleteCharAt(1);
} else {
buf.append(yearValue + 10000).deleteCharAt(0);
}
// ...
}
}
Currently, LocalDate.toString causes an extra memory copy when processing years
< 1000. This can be replaced by using StringBuilder.repeat, which is more
concise and has better performance.
