Java Class Library

yJava the platform contains around 4,000 classes/interfaces yData Structures yNetworking, Files yGraphical User Interfaces ySecurity and Encryption yImage Processing yMultimedia authoring/playback yAnd more... yAll neatly(ish) arranged into packages (see API docs)

Java's Collections Framework

<>

Collection<>

Collection<>

Collection<>

IterableyImportant chunk of the class library

yA collection is some sort of grouping of things (objects) yUsually when we have some grouping we want to go through it ("iterate over it") yThe Collections framework has two main interfaces: Iterable and Collections. They define a set of operations that all classes in the Collections framework support yadd(Object o), clear(), isEmpty(), etc.

Major Collections Interfaces I

y<> Set yLike a mathematical set in DM 1 yA collection of elements with no duplicates yVarious concrete classes like TreeSet (which keeps the set elements sorted) y<> List yAn ordered collection of elements that may contain duplicates yArrayList, Vector, LinkedList, etc. y<> Queue yAn ordered collection of elements that may contain duplicates and supports removal of elements from the head of the queue yPriorityQueue, LinkedLIst, etc.AB C A BC B A BC B

Major Collections Interfaces II

y<> Map yLike relations in DM 1, or dictionaries in ML yMaps key objects to value objects yKeys must be unique yValues can be duplicated and (sometimes) null. K1A B BK3K2

Iteration

yfor loop yforeach loop (Java 5.0+)LinkedList list = new LinkedList(); for (int i=0; iObject next = list.get(i);

LinkedList list = new LinkedList();

for (Object o : list) {

Iterators

yWhat if our loop changes the structure? yJava introduced the Iterator class ySafe to modify structurefor (int i=0; iIf (i==3) list.remove(i);

Iterator it = list.iterator();

while(it.hasNext()) {Object o = it.next();} for (; it.hasNext(); ) {Object o = it.next();} while(it.hasNext()) { it.remove();

Collections and Types I

yThe original Collections framework just dealt with collections of Objects yEverything in Java "is-a"

Object so that way our

collections framework will apply to any class yBut this leads to: yConstant casting of the result (ugly) yThe need to know what the return type is yAccidental mixing of types in the collection// Make a TreeSet object

TreeSet ts = new TreeSet();

// Add integers to it ts.add(new Integer(3)); // Loop through iterator it = ts.iterator(); while(it.hasNext()) {

Object o = it.next();

Integer i = (Integer)o;

Collections and Types II

// Make a TreeSet object

TreeSet ts = new TreeSet();

// Add integers to it ts.add(new Integer(3)); ts.add(new Person("Bob")); // Loop through iterator it = ts.iterator(); while(it.hasNext()) {

Object o = it.next();

Integer i = (Integer)o;

}Going to fail for the second element! (But it will compile: the error will be at runtime)

Java Generics

yTo help solve this sort of problem, Java introduced

Generics in JDK 1.5

yBasically, this allows us to tell the compiler what is supposed to go in the Collection ySo it can generate an error at compile-time, not run-time // Make a TreeSet of Integers

TreeSet ts = new TreeSet();

// Add integers to it ts.add(new Integer(3)); ts.add(new Person("Bob")); // Loop through iterator it = ts.iterator(); while(it.hasNext()) {

Integer i = it.next();

}Won't even compile

No need to cast :-)

Generics Declaration and Use

public class Coordinate { private T mX; private T mY; public Coordinate(T x, T y) { mX=x; mY=y; public T getX() { return mX; } public T getY() { return mY; }
