JarCastingversion4j
=============
Library to help compare major.minor.patch versions.
Implements the standard Comparable and Comparator Interfaces.
Usage
Stable:

<artifactId>version4j</artifactId>
<version>4.0</version>
</dependency>
Examples
Parse Version
Attempts to parse the String to Version Object. Throws VersionNotValidException if fails to parse the String.
Currently only support major.minor.patch format. And the value of any of these parts cannot be greater than 100000.
Version.parseVersion("1.1.2"); //parsed as 1.1.2
Version.parseVersion("1"); //parsed as 1.0.0
Version.parseVersion("1.2"); //parsed as 1.2.0
Version.parseVersion("1.2.3c"); //parsed as 1.2.3
Version.parseVersion("1.2.3c"); //parsed as 1.2.3
Version.parseVersion("1.2.3.4.5"); //parsed as 1.2.3
Version.parseVersion(" "); //throws VersionNotValidException
Version.parseVersion(null); //throws VersionNotValidException
Version.parseVersion("100001.0.0"); //throws VersionNotValidException
Try Parse
Tries to parse the passed String. Returns true if successfully parses the String or returns false.
This method does not throw an exception.
Version.tryParse("1.1.2"); //true
Version.tryParse("1"); //true
Version.tryParse("1.2"); //true
Version.tryParse("1.2.3c"); //true
Version.tryParse("1.2.3c"); //true
Version.tryParse("1.2.3.4.5"); //true
Version.tryParse(" "); //false
Version.tryParse(null); //false
Version.tryParse("100001.0.0"); //false
CompareTo
Standard Comparable interface
Version v1 = new Version("1.2.3");
Version v2 = Version.parseVersion("1.2");
v1.compareTo(v2); //1
Greater than
Version v1 = new Version("0.1.9");
Version v2 = new Version("0.0.9");
v1.greaterThan(v2); //true
Less than
Version v1 = new Version("2.0.9");
Version v2 = new Version("10.0.1");
v1.lessThan(v2); //true
Sort Versions
Sorts the versions in ascending order
Version v1 = new Version("2.0.0");
Version v2 = new Version("0.095.3");
Version v3 = new Version("10.0.1");
Version v4 = new Version("0.0.1");
List<Version> versions = new ArrayList<Version>();
versions.add(v1);
versions.add(v2);
versions.add(v3);
versions.add(v4);
versions.sort(new VersionComparator());
