Java

Write a generic class that represents a Quad, defined as a pair of Pair objects. The Pair objects could hold different types (for example, a Quad could be made up of a Pair of Integers and a Pair of Strings). Post the class header, instance data variables, constructor, and equals method. Two Quad objects are equal if the two pairs in the current Quad are equal to the two pairs in the other Quad, ignoring order
