Java.lang.Enum Class
Introduction
The java.lang.Enum class is the common base class of all Java language enumeration types.
Class Declaration
Following is the declaration for java.lang.Enum class −
public abstract class Enum<E extends Enum<E>> extends Object implements Comparable<E>, Serializable
Class constructors
Sr.No. | Constructor & Description |
---|---|
1 |
protected Enum(String name, int ordinal) This is the single constructor. |
Class methods
Sr.No. | Method & Description |
---|---|
1 | protected Object clone()
This method throws CloneNotSupportedException. |
2 | int compareTo(E o)
This method compares this enum with the specified object for order. |
3 | boolean equals(Object other)
This method returns true if the specified object is equal to this enum constant. |
4 | protected void finalize()
This method returns enum classes cannot have finalize methods. |
5 | Class<E> getDeclaringClass()
This method returns the Class object corresponding to this enum constant's enum type. |
6 | int hashCode()
This method returns a hash code for this enum constant. |
7 | String name()
This method returns the name of this enum constant, exactly as declared in its enum declaration. |
8 | int ordinal()
This method returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero). |
9 | String toString()
This method returns the name of this enum constant, as contained in the declaration. |
10 | static <T extends Enum<T>> T valueOf(Class<T> enumType, String name)
This method returns the enum constant of the specified enum type with the specified name. |
Methods inherited
This class inherits methods from the following classes −
- java.lang.Object
