@param parameter-name description
Adds a parameter to the "Parameters" section. The description may be continued on the next line. This tag is valid only in a doc comment for a method or constructor.
The @param tag is followed by the name (not data type) of the parameter, followed by a description of the parameter. By convention, the first noun in the description is the data type of the parameter. (Articles like "a", "an", and "the" can precede the noun.) An exception is made for the primitive int, where the data type is usually omitted. Additional spaces can be inserted between the name and description so that the descriptions line up in a block. Dashes or other punctuation should not be inserted before the description, as the Javadoc tool inserts one dash.
Parameter names are lowercase by convention. The data type starts with a lowercase letter to indicate an object rather than a class. The description begins with a lowercase letter if it is a phrase (contains no verb), or an uppercase letter if it is a sentence. End the phrase with a period only if another phrase or sentence follows it.
