在 java.time (YYYY-MM-DD) 中解析 ISO 8601 格式的仅日期值

Question

How do I parse YYYY-MM-DD dates in modern Java?

I have a Java String of a standard ISO 8601 date in the YYYY-MM-DD format, such as 2016-03-21 .

How can I parse this into the modern Date-Time types in Java, the java.time classes?

Note: This is intended to be a canonical post for a common question.

Answer 1

LocalDate.parse

The java.time classes can parse ISO 8601 strings directly, with no need to specify a formatting pattern.

For a date-only value, without a time of day or time zone, use the LocalDate class.

LocalDate ld = LocalDate.parse("2016-03-21");
