[corey williams]

everytime i write java code i get symbol cannot be found error message what does the erro mean and how can i fix it

[Joy Mookerji]

Can you give some detail of your error
Then its easy to diagonize

check PATH=C:\jdk1.4\bin
CLASSPATH = C:\jdk1.4\lib\tools.jar;C:\jdk1.4\jre\lib\rt.jar

[Jean-Francois Briere]

Could you post the relevant part of the code and the exact error message output please so we'll be able to help you.

i'm useing netbeans

import java.util.*;
public class DotComBust {

private GameHelper helper = new GameHelper();
private ArrayList<DotCom> dotComList = new ArraryList<DotCom>();
private int numOfGuesses = 0;

/** Creates a new instance of DotComBust */
private void setUpGame() {

DotCom one = new DotCom();
one.setName("Pets.com");
DotCom two = new DotCom();
one.setName("eToys.com");
DotCom three = new DotCom();
one.setName("Go2.com");
dotComList.add(one);
dotComList.add(two);
dotComList.add(three);

System.out.println("Your goal is to sink three dot coms");
System.out.println("pets.com, eToys.com, Go2.com");
System.out.println("Try to sink the all in the fewest number of guesses");

for (DotCom dotComToSet : dotComList) {

Arraylist<string> newLocation = helper.placeDotCom(3);

dotComToSet.setLocationcells(newLocation);

}
}

i'm getting the error on the decliration og the arraylist and also for my gamehelper object, and for the dotcom objectt that i create, and the error say that it can't find the symbol, and then it tells me the symbol and the location

[Jean-Francois Briere]

Are the DotCom and GameHelper classes part of your project?
Or are those classes from an external jar file?

[corey williams]

there classes that i have not created yet

[Jean-Francois Briere]

Then this is clearly the reason why the compiler cannot find the symbols DotCom and GameHelper isn't it?
Simply creates the classes with the appropriate methods even though there is no implementation in the methods.
For instance:

import java.util.*;
public class DotCom {
    public void setName(String name) {
    }
    public void setLocationcells(Arraylist<string> location) {
    }
}

[corey williams]

now what about my arraylist it gives me the same error for my arraylist

[John Bartlett]

In the code you have shown you have spelt ArrayList wrong....

John

[corey williams]

i don't see the misspelling can you point it out to me please

[John Bartlett]

The error is here....

private ArrayList<DotCom> dotComList = new ArraryList<DotCom>();  

...

Change to:

private ArrayList<DotCom> dotComList = new ArrayList<DotCom>();  

John

i don't see the misspelling can you point it out to me please

The misspelling is in:

Arraylist<string> newLocation = helper.placeDotCom(3);

You have to use "ArrayList" instead of "Arraylist".

[Burkhard Hassel]

Hi!

Arraylist<string> newLocation = helper.placeDotCom(3);


ArrayList, not Arraylist.


BTW,
are you sure you are using java5?
Generics won't work with earlier versions.

[Gabriel Fairbanks]

The error is here....

code:


private ArrayList<DotCom> dotComList = new ArraryList<DotCom>();



...

Change to:

code:


private ArrayList<DotCom> dotComList = new ArrayList<DotCom>();



John

Oops... I think I've found another one instead hehehe

[John Bartlett]

Lol yeah i think there are a few around, just found another little thing in the:

 
Arraylist<string> newLocation = helper.placeDotCom(3);
 

You also have appeared to have used string instead of String, that will also need to be corrected.

[Burkhard Hassel]

... and String, in uppercase.

Arraylist<string> newLocation = helper.placeDotCom(3);

[Burkhard Hassel]

Hey John Bartlett,
me and you are locking on the same object
this thread has to be

synchronized

[John Bartlett]

Lol! yeah

[corey williams]

ok thanks
