Java 5.0

This interface extends Type and represents a generic type declared with a bounded or unbounded wildcard. getUpperBounds( ) returns the upper bounds of the wildcard. The returned array always includes at least one element. If no upper bound is declared, Object.class is the implicit upper bound. getLowerBounds( ) returns the lower bounds of the wildcard. If no lower bound is declared, this method returns an empty array .
