Method Details

values

public static MeasurementSystem[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static MeasurementSystem valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

getLengthUnitSymbol

public String getLengthUnitSymbol()

Retrieves the length unit symbol for this measurement unit.

Returns:

the length unit symbol

getWeightUnitSymbol

public String getWeightUnitSymbol()

Retrieves the weight unit symbol for this measurement unit.

Returns:

the weight unit symbol

convertToDisplayString

public String convertToDisplayString()

Retrieves a user-friendly display string for the measurement unit.

Returns:

the display string

fromDisplayString

public static MeasurementSystem fromDisplayString(String displayString)

Finds a MeasurementUnit by its display string.

Parameters:

displayString - the display string to search for

Returns:

the corresponding MeasurementUnit

Throws:

IllegalArgumentException - if no match is found

convertLength

public double convertLength(double length,
 MeasurementSystem toUnit,
 boolean exact)

Converts the given length value from the current unit to the target unit.

Parameters:

length - the length value to convert

exact - whether to round the result to two decimal places

Returns:

the converted length value

convertWeight

public double convertWeight(double weight,
 MeasurementSystem toUnit,
 boolean exact)

Converts the given weight value from the current unit to the target unit.

Parameters:
