Method Detail

values

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

Returns:

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

valueOf

public static ElectricCharge 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

getCharge

public CRational getCharge()

Gets the electric charge as a fraction..

Returns:

The electric charge as a fraction.

toString

public String toString()

Creates a String representation of this ElectricCharge.

Overrides:

toString in class Enum<ElectricCharge>

Returns:

A String representation of this ElectricCharge.
