Overview. In this tutorial you will learn how to refactor your code in order to leverage the new Date Time API introduced in Java 8. 2. New API at a Glance. Working with dates in Java used to be hard. The old date library provided by JDK included only three classes: java.util.Date, java.util.Calendar and java.util.Timezone. The java.time.Year class represents a year in the ISO-8601 calendar system, such as 2021. Year is an immutable date-time object that represents a year. This class does not store or represent a month, day, time, or time-zone. The years represented by this class follow the proleptic numbering system that is as follows: A couple of things: 1) I strongly recommend you start using the java.time API with its formatters, 2) "The SampleDateFormat is giving wrong format" - no, you're using SimpleDateFormat to parse the string into a java.util.Date and then call toString() on it which returns the default representation of the date. You'd need to use another formatter Since it is in German, here the terms line by line from left to right: year, month, day. And on the left (from top to bottom) test date, date of birth, age. I would like the client to first enter the test date in the first line, spread over three fields, e.g. 2021 - 04 - 09 and below the date of birth, e.g. 1990 - 11 - 17. 2. Write a program reads two integers representing a month and day and prints the season for that month and day. Assume that months are specified as an integer between 1 and 12 (1 for January, 2 for February, and so on) and that the day of the month is a number between 1 and 31. If the date falls between 12/16 and 3/15, you should print "Winter A LocalDate is supposed to represent date units (year, month, day), and not a specific format. The default format used by LocalDate#toString is based on ISO 8601 standard. For a specific format, you need to format it into a String as shown above. It is like representing double d = 5.0 as the 5.000 which is done by formatting d into a String of .
