tl dr  LocalDate parse   2015-01-02      java time  Java 8 and later has a new java time framework that makes these other answers outmoded  This framework is inspired by Joda-Time  defined by JSR 310  and extended by the ThreeTen-Extra project  See the Tutorial   The old bundled classes  java util Date  Calendar  are notoriously troublesome and confusing  Avoid them   LocalDate  Like Joda-Time  java time has a class LocalDate to represent a date-only value without time-of-day and without time zone    ISO 8601  If your input string is in the standard ISO 8601 format of yyyy-MM-dd  you can ask that class to directly parse the string with no need to specify a formatter    The ISO 8601 formats are used by default in java time  for both parsing and generating string representations of date-time values   LocalDate localDate   LocalDate parse   2015-01-02       Formatter  If you have a different format  specify a formatter from the java time format package  You can either specify your own formatting pattern or let java time automatically localize as appropriate to a Locale specifying a human language for translation and cultural norms for deciding issues such as period versus comma   Formatting pattern  Read the DateTimeFormatter class doc for details on the codes used in the format pattern  They vary a bit from the old outmoded java text SimpleDateFormat class patterns   Note how the second argument to the parse method is a method reference  syntax added to Java 8 and later   String input    January 2  2015   DateTimeFormatter formatter   DateTimeFormatter ofPattern    MMMM d  yyyy    Locale US    LocalDate localDate   LocalDate parse   input   formatter      Dump to console   System out println    localDate      localDate         localDate  2015-01-02   Localize automatically  Or rather than specify a formatting pattern  let java time localize for you  Call DateTimeFormatter ofLocalizedDate  and be sure to specify the desired expected Locale rather than rely on the JVM   s current default which can change at any moment during runtime      String input    January 2  2015   DateTimeFormatter formatter   DateTimeFormatter ofLocalizedDate   FormatStyle LONG    formatter   formatter withLocale   Locale US    LocalDate localDate   LocalDate parse   input   formatter      Dump to console    System out println    input      input       localDate      localDate         input  January 2  2015   localDate  2015-01-02

The highly regarded Joda Time library is also worth a look   This is basis for the new date and time api that is pencilled in for Java 7   The design is neat  intuitive  well documented and avoids a lot of the clumsiness of the original java util Date   java util Calendar classes     Joda s DateFormatter can parse a String to a Joda DateTime
