Write a program that checks that all the CdName-objects that are used in the glue part or the traversals part of an Input-object are defined in the cds part of the same Input-object. Your program must print "true" or "false". Use the "containsAll" method of interface Collection: boolean containsAll(Collection c) Returns true if this collection contains all of the elements in the specified collection c. The class graph object of class ClassGraph is available in variable cg. Find the UNKNOWNs below. The Input object is in variable i. List defined = UNKNOWN.UNKNOWN(i, " from UNKNOWN " + " UNKNOWN + " via UNKNOWN " + " to edu.neu.ccs.demeter.Ident"); List used = UNKNOWN.UNKNOWN(i, " from UNKNOWN " + " UNKNOWN " + " via UNKNOWN " + " to edu.neu.ccs.demeter.Ident"); System.out.println(UNKNOWN.UNKNOWN(UNKNOWN));
