Enum JRE


  • @API(status=STABLE,
     since="5.1")
public enum JRE
extends java.lang.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

      • 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​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.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
