Method Detail

values

public static JavaVersion[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (JavaVersion c : JavaVersion.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static JavaVersion valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

toString

public String toString()

Overrides:

toString in class Enum<JavaVersion>

getJavaVersion

public static JavaVersion getJavaVersion()

Returns the JavaVersion of the current runtime.

Returns:

the JavaVersion

isEqualOrNewerThan

public boolean isEqualOrNewerThan(JavaVersion version)

Return if this version is equal to or newer than a given version.

Parameters:

version - the version to compare

Returns:

true if this version is equal to or newer than version

isOlderThan

public boolean isOlderThan(JavaVersion version)

Return if this version is older than a given version.

Parameters:

version - the version to compare

Returns:

true if this version is older than version
