Instances of this class are immutable. Field Summary public static  String USD      The constant to denote US Dollar. Constructor Summary public   Currency()      Default constructor. public   Currency(double value)      Constructs a Currency object with the specified value. public   Currency(String s)      Constructs a Currency object with the specified value. public   Currency(Double value)      Constructs a Currency object with the specified value. public   Currency(double value, String currencyType)      Constructs a Currency object with the specified value and currency type A RuntimeException will be thrown if the input currency type is not supported. public   Currency(String s, String currencyType)      Constructs a Currency object with the specified value and currency type A RuntimeException will be thrown if the input currency type is not supported. public   Currency(Double value, String currencyType)      Constructs a Currency object with the specified value and currency type A RuntimeException will be thrown if the input currency type is not supported. Method Summary public  Currency add(Currency c)      Returns a new Currency object, which has the same currency type as this object, and a value which is the sum of the 2 Currency objects. public  Object clone()      Returns a clone of the object. public  int compareTo(Object obj)      Compares this object with another Currency object. Note: this class has a natural ordering that is inconsistent with equals The target object is converted to the same currencyType before the comparison is performed. Hence, it is quite possible that this method might indicate a equality, while the 'equals' method may return a false. Parameters:   obj - the other Currency object. public  Currency convert(String currencyType)      Returns a new Currency object, which will have the value of the current object converted to the input currency type. A RuntimeException will be thrown if the input currency type is not supported. Parameters:   currencyType - the type to convert to. public  boolean equals(Object obj)      Compares this object with another Currency object. Returns a true if both the objects have the same currency type and value. Parameters:   obj - the other Currency object. public  String getCurrencyType()      Getter for property currencyType. public  Double getValue()      Getter for property value. public  int hashCode()      Returns an int which will be the sum of the of the hashcodes of the value and the currency type. public  String toString()      Returns the diagnostic information. Field Detail USD public static String USD(Code) The constant to denote US Dollar. Constructor Detail Currency public Currency()(Code) Default constructor. This creates a Currency object with 0 value. This will default to USD as the currency type. Currency public Currency(double value)(Code) Constructs a Currency object with the specified value. This will default to USD as the currency type. Parameters:   value - the value of the object. Currency public Currency(String s)(Code) Constructs a Currency object with the specified value. This will default to USD as the currency type. Parameters:   s - the value of the object. Currency public Currency(Double value)(Code) Constructs a Currency object with the specified value. This will default to USD as the currency type. Parameters:   value - the value of the object. Currency public Currency(double value, String currencyType)(Code) Constructs a Currency object with the specified value and currency type A RuntimeException will be thrown if the input currency type is not supported. Parameters:   value - the value of the object. Parameters:   currencyType - the currency type. Currency public Currency(String s, String currencyType)(Code) Constructs a Currency object with the specified value and currency type A RuntimeException will be thrown if the input currency type is not supported. Parameters:   s - the value of the object. Parameters:   currencyType - the currency type. Currency public Currency(Double value, String currencyType)(Code) Constructs a Currency object with the specified value and currency type A RuntimeException will be thrown if the input currency type is not supported. Parameters:   value - the value of the object. Parameters:   currencyType - the currency type. Method Detail add public Currency add(Currency c)(Code) Returns a new Currency object, which has the same currency type as this object, and a value which is the sum of the 2 Currency objects. The input Currency is first converted to the same currency type, before adding the values. Parameters:   c - the other Currency object. a new Currency object which has the same currency type as this object, and a value which is the sum of the 2 Currency objects clone public Object clone()(Code) Returns a clone of the object. a clone of the object. compareTo public int compareTo(Object obj)(Code) Compares this object with another Currency object. Note: this class has a natural ordering that is inconsistent with equals The target object is converted to the same currencyType before the comparison is performed. Hence, it is quite possible that this method might indicate a equality, while the 'equals' method may return a false. Parameters:   obj - the other Currency object. a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. convert public Currency convert(String currencyType)(Code) Returns a new Currency object, which will have the value of the current object converted to the input currency type. A RuntimeException will be thrown if the input currency type is not supported. Parameters:   currencyType - the type to convert to. a new Currency object, which will have the value of the current object converted to the input currency type. equals public boolean equals(Object obj)(Code) Compares this object with another Currency object. Returns a true if both the objects have the same currency type and value. Parameters:   obj - the other Currency object. a true if both the objects have the same currency type and value. getCurrencyType public String getCurrencyType()(Code) Getter for property currencyType. Value of property currencyType. getValue public Double getValue()(Code) Getter for property value. Value of property value. hashCode public int hashCode()(Code) Returns an int which will be the sum of the of the hashcodes of the value and the currency type. an int which will be the sum of the of the hashcodes of the value and the currency type. toString public String toString()(Code) Returns the diagnostic information. the diagnostic information.
