Defining a variable outside a class.

Is there anyway I can define a variable outside a class, so that it can be accessable to many different classes. For instance if i have a String:
homedirectory="c:/home/". How can I make it other classes access the content of this string, without having to define it in every class??
Cheers.

Is there anyway I can define a variable outside a
class,No, all variables must be in a class.
so that it can be accessable to many different classes.A public static field can be accessed in any class.
For instance if i have a String: homedirectory="c:/home/". Do you mean like System.getProperty("user.home") ?
How can I make it other
classes access the content of this string, without
having to define it in every class??Use a system property so it can be set on the command line or a public final static field in a class.

1.
It should be
var theQuestion:Question = new
Question(sType,sCondition:string,sQnumber,sQheading,sPretext,sQtext,sPosttext,
sCodeframe,sReserved,sEditableFrom,sEditableTo,sDecimal,sSetQfactor,sLogic_if,sLogic_then )
As you don't have default values in the constructor - you
should specify the parameters.
2. why do use type "string" ? It should be "String" if you
refer to a standard type
3. What are you trying to say by this:
public var Codeframe():string;
public var Logic_if():string;
public var Logic_then():string;
There should not be any parenthesis in the variable
declaration.
4.
this is wrong
var Question():Question=new Question();
this even wronger
var Question():Array=new Question(); // I'm trying to create
an array here anyway...could this be the problem??
no parenthesis!
var Qs():Question=new Question();
hmmmm....
.var Qs()=new Question();
I think you should start reading from the following link to
get more understanding of the variables, types & declarations:

How define a global variable in a class that all the methods will recognize

hi friends,
i need to define a global variable in a class that all the methods will recognize it.
any suggestions?
thanks,
dana.

Dera Dana,
In se24, create your own "Z" class.
Open the Attributes tab.
Insert your variable in the declaration part.
EQ:
Attribute     Level                       Visibility   Typing      Associated Type         Description
ITAB     Instance Attribute     Public     Type     Structure name     Description
In the Layout of View page,
<phtmlb:formLayoutDropDownListBox id                = "Dropdown"
                                          label             = "Drop Down"
                                          table             = "<%= controller->Itab %>"
                                          nameOfKeyColumn   = "CODE"
                                          nameOfValueColumn = "VALUE"
                                          selection         = "<%= controller->feild to be selected %>"

Defining variables from a class gives errors

Hi,
I'm trying to create a questionnaire, that can hold an array
of questions.
The questions can be of different types, like single punch,
multi punch, open text etc.
Much of the code below is copied from examples I've found and
I am definitely in the beginning
of my learning process when it comes to Flex, but I think
Flex can solve a problem I have at work.
So, I'm trying to cut corners...
I created this class called Questions, which contains all
properties any question can have.
When I'm trying to define a variable (myQuestion) based on
that class, I the following error.
(actually I get it on all properties...)

When you create your local variable myQuestion, where are the
parameters (used in the constructor) declared and initialized?
var _qType = "some value";
var myQ:Question = new Question(_qType,"","" etc);
Also good OO practice is to declare your variables as private
and add getters and setters for the values. Sometimes you may want
to manipulate the values when getting or setting.
If you use the standard AS3 get and set then declare your
vars with an _
so as not to conflict with the getter and setter. For exampe:
public class MyClass
private var _var1:String;
public function get var1():String
return _var1;
public function set var1(v:String):void
_var1 = v;
This may seem like extra work, but in a complex application
with lots of classes
encapsulating updating of members will save you lots of
headaches.

How to pass a variable from one class to another class?

Hi,
Is it possible to pass a variable from one class to another? For e.g., I need the value of int a for calculation purpose in method doB() but I get an error <identifier> expected. What does the error mean? I know, it's a very, very simple question but once I learn this, I promise to remember it forever. Thank you.
class A {
int a;
int doA() {
      a = a + 1;
      return a;
class B {
int b;
A r = new A();
r.a; // error: <identifier> expected. What does that mean ?
int doB() {
     int c = b/a; // error: operator / cannot be applied to a
}Thank you!

elaine_g wrote:
I am wondering why does (r.a) give an error outside the method? What's the reason it only works when used inside the (b/r.a) maths function? This is illegal syntax:
class B {
int b;
A r = new A();
r.a; //syntax error
}Why? Class definition restricts what you can define within a class to a few things:
class X {
    Y y = new Y(); //defining a field -- okay
    public X() { //defining a constructor -- okay
    void f() { //defining a method -- okay
}... and a few other things, but you can't just write "r.a" there. It also makes no sense -- that expression by itself just accesses a field and does nothing with it -- why bother?
This is also illegal syntax:
int doB() {
      A r = new A();
      r.a; // error: not a statement
}Again, all "r.a" does on its own is access a field and do nothing with it -- a "noop". Since it has no effect, writing this indicates confusion on the part of the coder, so it classified as a syntax error. There is no reason to write that.

Loading Variables in a Class Function

I am having problems loading variables from an external text
file inside of a class function. The text file has been created
properly, and the code that I use in the class is as follows:
_root.createEmptyMovieClip("texRules", -100);
loadVariables("texRules.txt", _root.texRules);
m_Rules = _root.texRules.rules;
I create an empty movie clip on the root frame named
texRules, load the variables into that movie clip with the next
line and then set my member string value equal to the text file
variable named rules. When I run the program, I get an undefined
for my m_Rules.
Here is my texRules.txt:
rules=THESE ARE THE TEXAS HOLD'EM RULES.
Any ideas as to what I am doing incorrectly?

I've opted to use the LoadVars instead of creating an empty
movie clip and loading the variables there. Here is my new code.
public function setRules():Void
var rulesLoader:LoadVars = new LoadVars();
rulesLoader.onLoad = function (success:Boolean):Void
if (success)
trace(rulesLoader.rules);
this.m_Rules = rulesLoader.rules;
else
trace( "Unable to load external file.");
rulesLoader.load("texRules.txt");
Here is where I define my properties of my class:
class TexHoldem extends Game
//Class member properties
//Private Properties
private var m_Rules:String;
private var m_Target:MovieClip;
Here is my constructor:
public function TexHoldem(target)
this.m_Target = target;
super("Texas No Limit Hold'Em", 0, 1);
setRules();
The setRules function works fine, the only problem now is
that I can't save the variables once the onLoad function goes out
of scope. I've thought of modifying it so that it returns a type,
but that seems difficult. The two easiest solutions I see is to
create an empty text field that holds the string or find a way to
get the rulesLoader.rules outside of the onLoad scope. Any
suggestions now? Sorry to change the problem on you.

Is there a way to reference a private variable from one class in another?

My first class starts off by declaring variables like so:
class tStudent {
// declare student name, id, grades 1 & 2, and gpa
private String fname, lname, g1, g2;
private int id;
private double gpa;
// define a constructor for a new student
tStudent () {fname=lname=g1=g2=null; id=-1; gpa=0.0;}
// define methods for manipulating the data members.
// readStudent: reads information for just one student
public void read (Scanner input) {
      fname = input.next();
      lname = input.next();
      id = input.nextInt();
      g1 = input.next();
      g2 = input.next();
}And the second class:// tStudentList: for a list of students
class tStudentList {
private int nStudents;
private tStudent[] list;
// constructor for creating student list
tStudentList() {
      list = new tStudent[36];
      for (int i=0; i < 36; i++) list=new tStudent();
// read the individual students into the student list
public void read(Scanner scan) {
nStudents=0;
while (scan.hasNext()) {list[nStudents++].read(scan);}
// display the list of all students - fname, lname, id, g1, g2 and gpa
// with an appropriate header so the output matches my sample //output
public void print() {
Is there a way to reference the variables in the first class to use in the second? Specifically in the last section of code where I am going to print the list.

Not without resorting to reflection hackery. If the fields are private (and are supposed to be), then that means "don't allow access to these to outsiders of this class" by design.
So if you really meant them to be accessible, then don't use private, or provide public accessors for them.

Using a variable from one class to another

Hi !
I've a class called ModFam (file ModFam.java) where I define a variable as
protected Connection dbconn;
Inside ModFam constructor I said:
try
String url = "jdbc:odbc:baselocal";
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
dbconn = DriverManager.getConnection(url);
System.err.println("Connection successful");
} ..... rest of code
This class define a TabbedPane as follows:
tabbedPane.addTab("Welcome",null,new Familias(),"Familias");
As you can see it call a new instance of the Familias class (file Familias.java).
This constructor will try to connect with the DB to populate a combo box with some data retireved from the DB.
If I do
Statement stmt;
stmt = dbconn.createStatement();
inside Familias constructor I receive the message
Familias.java:50: cannot resolve symbol
symbol : variable dbconn
location: class fam.Familias
stmt = dbconn.createStatement();
at compile time.
While I can�t use a variable defined as "protected" in one class of my package on another class of the same package ?
How could I do ?
Thanks in advance
<jl>

Familias doesn't have a reference to ModFam or the Connection.
So change the constructor in Familias to be
public class Familias {
private ModFam modFam;
public Familias(ModFam m) {
modFam = m;
// ... somewhere else in the code
Statement stmt = modFam.dbconn.createStatement();
}or
public class Familias {
private Connection dbconn;
public Familias(Connection c) {
dbconn = c;
// ... somewhere else in the code
Statement stmt = dbconn.createStatement();
}And when you instantiate Familias it should then be
new Familias(this) // ModFam reference
or
new Familias(dbconn)

Sending a variable from one class to another?

Dear Java Users - please can you help me out here... I know that what I am asking should be straight forward BUT I just don't understand any of the responses people have put on the web....
Here is what I am trying to do:
This piece of code - creates a window with a simple textbox on it to enter a word...
The button then calls another class file to open a new window...

Well,
Using the constructor is the way to go. Otherwise create a method that takes the string as parameter.

To use a static variable in another class,but report NullPointerException

when TableMain is running,I run testRecord so that let TableMain add a occur informatin and
happened time in a row in TableMain,but when I run testRecord,java report a NullPointerException and I dont know how to solve this problem,thanks for helping me to check my code;(error report info is in end)

Exception in thread "main" java.lang.NullPointerException
at testRecord.main(testRecord.java:14)

but I just use this constructor once,never use twice
with same jvm;I thinks my idea is not too very badIt's a public constructor (if I'm looking in the right
place) - it could be called from anywhere. To
intialize a static variable outside the declaration,
use a static initializer:private static String whatever;static {
whatever = "whatever";
}Or simply (in this case):private static String whatever = "whatever";

Accessing public variables from other classes

Probably a simple questions, but how can I access a variable from another class. My exact situation is as follows.
A class called WorldCalender has a variable which is defined: public int hour; (the value is given to it elsewhere).
I want to access this variable and increase it by one in a subroutine in the class Hour. In this class I have put: WorldCalender.hour++; but it doesn't seem to work. How should I do it?

don't expose the hour variable at all.
have a method eg addToHourBy( int hrs )

I want to access this variable and increase it by one
in a subroutine in the class Hour. In this class I
have put: WorldCalender.hour++; but it doesn't seem to
work. How should I do it?

Use of variables from other class

hallo,
i have two classes A and B
i would like to access a variable of the class B out of A class
without class A extends B or
A classA = new A();
to use
i attempted it with a constructor
class A{
    B klb;
    public A(B b1){
    this.klb = b1;
   int a;
   a= klb.varausB;
}with that I get, however, a NullPointerException
in a similar form i saw it already once and it functioned
somebody can help me?

that is it what I mean
public class ClassA {
ClassB clb;
public ClassA (ClassB cb){
this.clb = cb;
public static void main(String[] args) {
System.out.println("Var from class B:
class B: "+clb.varb1);// there is an error, i know
but how it is right?
public class ClassB {
public String varb1 ="var b1";
}nevertheless so similarly it should function, or?So if you create an instance of ClassA, clb will be initialized. But you don't do that in main. Hence your errors:
1) You're not calling the constructor, so clb is null
2) You're trying to access an instance variable without having an instance, so clb is not only null, it actually doesn't exist.
public static void main(String[] args) {
Class A myA = new ClassA();
System.out.println("Var from class B: "+ myA.clb.varb1);
}You're outside of any object, ehnce you need to address clb through an instance of ClassA.

How to call a variable in another class????

if i have two classes in a package. From one class, how do i get the value of one of the variable in the other class.
For example;
Class A have a variable call totalNum which have a value initialise.
Class B wan to get the value variable totalNum in class A.
So do i go abt calling it?
Cheers

For example;
Class A have a variable call totalNum which have a
value initialise.
Class B wan to get the value variable totalNum in
class A.Your explanation is far from clear. Is the variable in class A a field? If yes, is it a static field? Is it declared public, private, etc.?
If you don't understand the above questions, you should do the following:
1) Learn the basics of the Java language from the Java Tutorial and/or from an entry-level book: http://java.sun.com/docs/books/tutorial/
2) Post future question in the New To Java Technology forum.

When I define a variable in BO it automatically turns it into a detail

i have made a user prompt in my report
so the user can input a value that does not exist in universe so i can use it as condition or a filter,
i have done this by using the followiing condition in the query
object = object
or
object = ToPrompt("Give number")
As you can see by the logic this condition will ALWAYS be true because object = object is always true. So this logic will not impact the rest of the query it will just allow to enter any value in the user prompt
in the report when i try to create a new variable
=ToNumber(UserResponse ("Query 1 with NEW_UNIV" , "Give number"))
it automatically turns it into a detail and i cant change it to measure or dimension.
is there a way to fix this
thanks in advance

some one answered in the following link

How to access variables from other class

    public boolean inIn(Person p)
        if (name == p.name && natInsceNo == p.natInsceNo && dateOfBirth == p.dateOfBirth)
             return true;
        else
             return false;
    }//returns true if Person with same name/natInsceNo/dateOfBirth as phello,
here am trying to compare the existing object with another object.
could you please tell me how to access the variables of other class because i meet this error?
name cannot be resolved!
thank you!

public class Person
    protected String name;
    protected char gender;      //protected attributes are visible in the subclass
    protected int dateOfBirth;
    protected String address;
    protected String natInsceNo;
    protected String phoneNo;
    protected static int counter;//class variable
//Constractor Starts, (returns a new object, may set an object's initial state)
public Person(String nme,String addr, char sex, int howOld, String ins,String phone)
    dateOfBirth = howOld;
    gender = sex;
    name = nme;
    address = addr;
    natInsceNo = ins;
    phoneNo = phone;
    counter++;
public class Store
    //Declaration of variables
    private Person[] list;
    private int count;
    private int maxSize;
//constructor starts
    public Store(int max)
         list = new Person[max];//size array with parameters
         maxSize = max;
         count = 0;
    }//end of store
//constructor ends
//accessor starts
    public boolean inIn(Person p)
       return (name == p.name && address == p.address && natInsceNo == p.natInsceNo);
    }//returns true if Person with same name/natInsceNo/dateOfBirth as phope it helps now!
