For a long time now the excellent Joda-Time<\/a> library has been the de facto date and time API for Java. Like SLF4J<\/a> or Guava<\/a> it is one of those dependencies that I seem to add by default to any new project but since the release of Java 8 users are asked to migrate to the new java.time<\/span> API. Finally Java has a date and time API it doesn’t need to be ashamed of.<\/p>\n\n\n\n

This new API is heavily influenced by the good design decisions of Joda-Time and much of its usage is similar but with years of writing Joda-Time code under my fingers I still find myself checking the new Javadoc from time to time for the subtle differences.<\/p>\n\n\n\n

Here is a short list of some common date\/time tasks using the new API. Interoperability with the old Date<\/span> class will often be a requirement for the near future so included are a couple of examples converting from java.util.Date<\/span> and java.sql.Date<\/span> to java.time<\/span>.<\/p>\n\n\n\n
