All Implemented Interfaces:

Serializable, Comparable<JRE>

@API(status=STABLE,
     since="5.1")
public enum JRE
extends Enum<JRE>

Enumeration of Java Runtime Environment (JRE) versions.

If the current JRE version cannot be detected — for example, if the java.version JVM system property is undefined — then none of the constants defined in this enum will be considered to be the current JRE version.

Since:

5.1

Method Detail

values

public static JRE[] 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 (JRE c : JRE.values())
    System.out.println(c);

Returns:

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

valueOf

public static JRE 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

isCurrentVersion

public boolean isCurrentVersion()

Returns:

true if this JRE is known to be the Java Runtime Environment version for the currently executing JVM
