Write a fully-documented class named Transaction which contains the date (String), amount (double) , and description (String). You should provide accessor methods for each variable, but no mutator methods. This is because a transaction should never be modified after being created. The full list of required methods is:public Transaction - Constructor (you may include a constructor with parameters)Getter methods for each variablepublic Object clone() - The return value is a copy of this Transaction. Subsequent changes to the copy will not affect the original and vice versa. Note that the return value must be typecasted to a Transaction before it can be used. Note that the copy being returned must be a deep copy. public boolean equals(Object obj) - A return value of true indicates that obj refers to a Transaction object with the same attributes as this Transaction. Otherwise, the return value is false. You will also need the following variables:a. String dateb. Double amountc. String description
