    • getSubversion

      public static final int getSubversion(String version, int portion)
      Returns a portion of the specified version in an integer, or 0 if no such portion exists.

      For example, getSubversion(0) returns the so-called major version (2 in "2.4.0"), and getSubversion(1) returns the so-called minor version (4 in "2.4.0").

      Note: alpha is consider as -500, beta -300, and rc -100. Moreover, beta3 is -497 (= -500 + 3) and rc5 -95 (-100 + 5)

      Parameters:
      version - the version. The version is assumed to a series of integer separated by a non-alphanumeric separator.
      portion - which portion of the version; starting from 0. If you want to retrieve the major version, specify 0.
