Container of J2SE _collection_iterator_set_list_comparable

The concept of containers

Container API

Collection Interface

ImportJava.util.*; Public classBasiccontainer { Public Static voidMain (string[] args) {Collection C=NewHashSet (); C.add ("Hello"); C.add (NewName ("F1", "L1")); C.add (NewInteger (100)); C.remove ("Hello"); C.remove (NewInteger (100)); System.out.println (C.remove (NewName ("F1", "L1")));    System.out.println (c); }}classNameImplementsComparable {PrivateString Firstname,lastname;  PublicName (String firstName, String lastName) { This. firstName = FirstName; This. LastName =LastName; }     PublicString Getfirstname () {returnFirstName; }     PublicString Getlastname () {returnLastName; }     PublicString toString () {returnFirstName + "" +LastName; }         Public Booleanequals (Object obj) {if(objinstanceofName) {Name Name=(Name) obj; return(Firstname.equals (name.firstname))&&(Lastname.equals (name.lastname)); }        return Super. Equals (obj); }         Public inthashcode () {returnFirstname.hashcode (); }                                 Public intcompareTo (Object o) {Name n=(Name) o; intLASTCMP =Lastname.compareto (n.lastname); return(lastcmp!=0?LastCmp:firstName.compareTo (n.firstname)); }        }
