Method Detail

majorVersion

public JavaVersion majorVersion()

Get the major version associated with this full version

onlyMajorVersionAndVendor

public JavaVersion.FullVersion onlyMajorVersionAndVendor()

Get a full version with the maintenance, update and release type zeroed out.

maintenance

Get the update associated with this full version

vendor

public JavaVersion.VendorType vendor()

Get the vendor associated with this full version

location

supports

public boolean supports(JavaVersion v)

Convenience method calling majorVersion().supports(v)

compareTo

public int compareTo(JavaVersion.FullVersion v)

Compare two versions. Major, maintenance, and update numbers are ordered sequentially. When comparing two versions that are otherwise equivalent, early access releases precede betas, followed by release candidates and stable releases. Within the release types, Unrecognized < OpenJDK < Apple < Oracle. Versions with unknown vendor are only equal if their locations are also equal.
