Method Detail

values

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

Returns:

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

valueOf

public static Lepton 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

getSymbol

public String getSymbol()

Gets the symbol of this Lepton.

Returns:

The symbol of this Lepton.

getGeneration

public Generation getGeneration()

Gets the generation of this Lepton.

Returns:

The generation of this Lepton.

getElectricCharge

public ElectricCharge getElectricCharge()

Gets the ElectricCharge of this Lepton.

Returns:

The ElectricCharge of this Lepton.

getSpin

public Spin getSpin()

Gets the Spin of this Lepton, which is always Spin.ONE_HALF.

Specified by:

getSpin in interface SubatomicParticle

Returns:

The Spin of this Lepton.

isElementary

public boolean isElementary()

Determines whether this subatomic particle is elementary or not.
An elementary particle cannot be divided into other particles.

Specified by:

isElementary in interface SubatomicParticle

Returns:

True.

toString

public String toString()

Creates a String representation of this Lepton.

Overrides:

toString in class Enum<Lepton>

Returns:

A String representation of this Lepton.
