Object[] an object array containing all the elements in the Enumeration

createObjectArray

public static java.lang.Object[] createObjectArray(java.util.Vector v)

A static method that creates an array of Object from a Vector.

Parameters:

v - - an instance of java.util.Vector

Returns:

num - - an instance of Enumeration that is known to contain only elements of type java.lang.String.

Returns:

String[] an array of Strings contained in the Enumeration.

createStringArray

public static java.lang.String[] createStringArray(java.util.Vector v)

A static method that creates an array of type String from a Vector. This method should only be used if it is known that all the elements in the Vector are of type String. Otherwise use createObjectArray.

Parameters:

v - - an instance of Vector that is known to contain only elements of type String.

Returns:

String[] an array of Strings contained in the Vector.

createVector

public static java.util.Vector createVector(java.lang.Object[] objects)

Creates a Vector from an array of Objects.

Parameters:

objects - The array to convert

Returns:

A vector populated with the objects in 'objects'

createEnumeration
