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

atLeast

public boolean atLeast(JavaVersion requiredVersion)

Whether this version of Java is at least the version of Java passed in.

For example:
myVersion.atLeast(JavaVersion.JAVA_1_4)

Parameters:

requiredVersion - the version to check against, not null

Returns:

true if this version is equal to or greater than the specified version

toString

public String toString()

The string value is overridden to return the standard name.

For example, "1.5".

Overrides:

toString in class Enum<JavaVersion>

Returns:

the name, not null
