Access (odifier /eserved $ords public8 private8 protected in Java. Control $"et"erclasses and members ma# be accessed from an# class8 onl# t"is class8subclasses. Default is access from an# class in t"e pac7age.

Agile ?or E=treme@Development

(et"odolog# for developing soft$are t"at emp"asi1es8 among ot"ert"ings8 unit testing as part of development process.

A+I ?Application+rogramming Interface@

T"e $a# one program uses anot"er program. In Java8 t"e A+I can bet"oug"t of as t"e collection of public met"ods for a class or pac7age.

Class (ain building bloc7 in Java. Contains members8 including fields andmet"ods. Classes are t"e blueprint for creating obects.

Constructor )pecial bloc7 of code used to create an instance of a class ?or8 if #ouprefer8 an obect $"ose t#pe is t"e class@. 6sed $it" t"e ne$ 7e#$ord?e.g.8 +erson p ne$ +erson?@ calls t"e +erson?@ constructor@.

Field (ember in a class t"at "olds data ?e.g.8 name8 age8 etc.@. 6suall# mar7edprivate so t"at ot"er programs cannot directl# access.

J( ?Java irtual(ac"ine@ ?also 7no$n asJava /untime Engine orJ/E@

T"e program t"at runs Java programs on a specific platform. Java sourcecode is compiled into .class files. T"ese contain t"e instructions used b#t"e J( to actuall# run t"e programs on a !indo$s +C8 a ,inu= computer8a (ac computer8 etc. T"e J( is $ritten for eac" platform supported b#Java.

J6nit Test A Java class used to test individual met"ods in a class. 6sed to build testcases8 e.g.8 $"en using agile development met"odolog#.

(et"od Argument8 (et"od+arameter

+arameters refers to t"e list of variables in a met"od declaration.Arguments are t"e actual values t"at are passed in $"en t"e met"od is

invo7ed. !"en #ou invo7e a met"od8 t"e arguments used must matc" t"edeclarationKs parameters in t#pe and order. For e=ample8 in t"e met"od

public setame?)tring name@ XP

name is t"e parameter for t"is met"od. If t"is met"od is used as follo$s

m#Obect.setame?Fred@V

Fred is t"e argument of t"e met"od and it must matc" t"e t#pe of t"emet"odGs parameter.

(et"od )ignature A met"odGs name plus itGs parameter list. For e=ample8 a met"od definedas setame ?)tring name@ "as a met"od signature of setame?)tring@.(et"od signatures are important because t"e# allo$ met"ods to beoverloaded ?i.e.8 "ave t"e same name but different signatures@. Fore=ample8 t"e met"od setame?)tring firstame8 )tring lastame@ couldbe an overload of setame?)tring name@ because it as a differentsignature ?setame?)tring8 )tring@@.

Obect An instance of a class. For e=ample8 Coo7ie could be a class8 and acoo7ie ?e.g. t"isCoo7ie@ $ould be an obect created using t"e class. In

ot"er $ords8 t"isCoo7ie is an obect of t#pe Coo7ie or an instance ofCoo7ie.

Overload ?(et"od@ To provide multiple met"ods $it" t"e same name but different parameters?i.e.8 same name but different signatures@.

Override ?(et"od@ !"en a subclass implements a met"od in"erited from t"e super class8 t"ismet"od is said to be overridden.

+ac7age +ac7ages are imported into a source file to save t#ping t"e full name oft"e class ?e.g.8 can sa# +erson instead of

org.eclipsetraining.librar#tutorial.+erson and to avoid t"e possibilit# oft$o classes "aving identical names.

+roect In Eclipse8 a $a# to organi1e #our $or7. An Eclipse $or7space cancontain multiple proects. Eac" proect can contain multiple pac7ages.Eac" pac7age can contain multiple classes.

/efactor To improve a program $it"out c"anging t"e $a# it $or7s ?i.e.8 its [email protected]=ample include renaming fields or variables8 streamlining code8 etc. er#

important in agile development because of emp"asis on self0documentingcode.

/eference ariable In Java8 variable t"at "olds an obect reference ?e.g.8 p ne$ +erson?@V@.+oints to an area on t"e "eap $"ere t"e obect resides. Contrast $it"value variable.

)crapboo7 +age Area in Eclipse $"ere #ou can e=ecute Java code snippets and see "o$t"e# $or7. 'reat for e=perimenting $it" Java statements.

)tatic (et"od A met"od t"at belongs to t"e entire class instead of one instance of t"e

class. Invo7ed $it" QClassR.Q(et"odR ?e.g.8 +erson.getTotalCount?@@.6sed for met"ods t"at donGt rel# on an# one instance of a class.

)!T ?)tandard !idgetTool7it@

)et of Java classes and native programs developed b# Eclipse to allo$Java programs to "ave t"e loo7 and feel of native programs on eac"platform. 6sed to create t"e Eclipse IDE.

T#pe In Java8 an attribute of a variable to indicate eit"er a primitive t#pe ?int8

boolean8 etc.@ or class members"ip. For obects8 t"e t#pe is t"e class to$"ic" it belongs. T#pes also include interfaces and enumerations.
