Regarding Scanner Object -- Cannot Resolve the Symbol

Hi,
I am new to Java, as well as this Forum.
Today I tried with Scanner object. But it shows Error.
My Code:
import java.util.Scanner;
public class CourseGradeBookTest
*     public static void main(String args[])*
*          Scanner input=new Scanner(System.in);*
*          CourseGradeBook CGB=new CourseGradeBook();*
*          System.out.println("Course Grade Book");*
*          String NameofCourse=input.nextLine();*
*          System.out.println();*
*          CGB.displayMessage(NameofCourse);*
Errors:
CourseGradeBookTest.java:1: cannot resolve symbol
symbol : class Scanner
location: package util
import java.util.Scanner;
*^*
CourseGradeBookTest.java:7: cannot resolve symbol
symbol : class Scanner
location: class CourseGradeBookTest
Scanner input=new Scanner(System.in);
*^*
CourseGradeBookTest.java:7: cannot resolve symbol
symbol : class Scanner
location: class CourseGradeBookTest
Scanner input=new Scanner(System.in);
*^*
*3 errors*
I went through the Previous Questions which were related to My Question. I checked with My Java Version..its java version "1.6.0_02"
Can You please help Me to get out of this problem.
Regards
Rajan.

hi
i think u didnt set path currectly.
u can set path in two ways.
1) By Using Environmen Varibles
2) By Creating .bat file.
for creating environmental variables
right click on MyCompueter->properties->Advanced->Environment Variables->

Cannot resolve the symbol while using use bean in jsp

Hi,
          Jsp with weblogic version 4.5 were running fine. When running on
          weblogic server 6.1 I get an error while running jsp pages cannot resolve
          symbol
          probably due to
          <jsp:useBean id = "hmllinkbean1" class="com.accupac.html.htmllink.LinkRS"/>
          I have the bean classes in
          config/accudomain/applications/DefaultWebApp_myserver/Web-inf/classes/
          and jsp files in the directory
          config/accudomain/applications/DefaultWebApp_myserver/
          Any help will be appreciated.
          Thanks

Three possibilities:
          Is your directory name really "Web-inf"? That will not work. It needs to be "WEB-INF".
          In WEB-INF, do you have:
          classes/com/accupac/html/htmllink/LinkRS.class
          When you say "cannot resolve symbol", is it the LinkRS class that it can't resolve?

Problem : Cannot resolve the collation conflict between ...

Hi
I want select a column from another database base on my current field on current database.
here is my query :
select ms.ServiceID, ms.ServiceName, ms.CoefficientFixedService,
(select Services_Name from MpAdmisson..IAServices_Table where Services_DepartmentID=24 and Services_Name=ms.ServiceName) as N'MpServiceName'
from MedicalServices ms
join MedicalCategories mc on ms.MedicalCategorizationID=mc.MedicalCategorizationID
join Zones z on mc.ZoneID=z.ZoneID
where z.ZoneID=24
but I'm facing this error :
Cannot resolve the collation conflict between "Persian_100_CI_AI" and "Arabic_CI_AS" in the equal to operation.
Also i changed collation of "MpAdmisson" db to "Persian_100_CI_AI" and even restart msSqlServer service, but i'm facing the same error!
where is my problem and how to solve it ?
thanks in advance
http://www.codeproject.com/KB/codegen/DatabaseHelper.aspx

although you changed the collation of the database it does not mean that all the objects changed their collation too automatically.
So far you are correct.
The change is only done when you change the data within the objects, thus recreating the table and moving data in / out or touching each and every value with doing something on the values themselves (the following will not work UPDATE (..) SET ServiceName
= ServiceName, the optimizer is smart enough too see that as a noop).
However, this is flat wrong. This is the story: each character column in a database has a collation tied to it. When you change the collation of a database, you change 1) the collation of the columns in the system tables. 2) The default collation. To change
the collation on the individual columns, you need to alter the column:
ALTER TABLE IAServices_Table
ALTER COLUMN Services_Name <current data type> COLLATE Persian_100_CI_AI [NOT] NULL
Unfortunately, this only works if the column is not indexed and has no constraints tied to it. Any indexes have to be dropped and recreated after the ALTER statement. If the column is a key column and there are referencing foreign keys, they also have to
be dropped and recreated. Thus, this is quite a far-reaching operation. And it may not stop there - with some amount of bad luck, constraints may fail with the new collation.
For this reason, this workaround suggested by Jens, may be your only option in the short term:
If you cannot do this currently, you can still do the following and collate on a per query basis:
select ms.ServiceID, ms.ServiceName, ms.CoefficientFixedService,
(select Services_Name from MpAdmisson..IAServices_Table where Services_DepartmentID=24 and Services_Name=ms.ServiceName COLLATE Persian_100_AS_CI) as N'MpServiceName'
from MedicalServices ms
And this part of Jens's post is correct. To note though is that use of the COLLATE clause voids any index on ServiceName. (Since this index is sorted according the rules of Arabic, and not the rules of Farsi.)

Cannot resovle the Symbol error in UDF - Java mapping - RFC Lookup ?

Hi Friends ,
We are working on Java mapping - UDF for RFC Lookup . It is giving the Cannot resolve Symbol for all imported archive java class files even if we give again all imported files in import section of UDF we are still getting the same cannot resolve error .
We are using SP 12 of XI 3.0 . What could be the reason ?
Thanks.,
V.Rangarajan

Hi,
Can you try to open imported archive in IR and check if the path(folder structure like com.abc.xyz.etc) for classes is same as in import statement in UDF.Since we had experienced the same problem.
Thanks.

I corrupted the firefox profile file using profile manager and firefox thinks it is still running and asks me to close but there is no instance of it running...I have tried several re-installs but cannot resolve the problem....

.........I have deleted the .ini file associated with the profile file and the profile file itself...have tried to locate the "lock" file but cannot find the file in the specified path on the support forum for this problem....I believe there is a file mounted in another directory somewhere that firefox is seeing....I would really like to be able to use firefox as the default browser on this new linux (ubuntu) install...it was working prior to my trying to import my profile from the windows partition.....

My MacBook cannot resolve the alias when attempting to connect to LAN wired devices (WD Live Media Centre), and says operation can't be comp-leted because the original item can't be found.???

I have 2 WD Live Media Centre devices hard-wired on my LAN. My MacBook can find these devices on the network, but when it tries to access the USB drive which is attached to the media centres, a message says the Mac it "resolving the alias to USB drive", but then says operation can't be completed because the roiginal item (USB Drive) can't be found. My PC, which is also hard-wired on the network, has no problem accessing these USB drives. Is there some adjustment I need to make?

Well, try this (I was able to fix my with these steps):
Go Utilities > Disk Utility
Select your Startup Disk, e.g. Macintosh HD
Then, under the First Aid Tab, click Verify Disk Permissions.
If there are errors, then click repair Disk Permissions.
After it is done, restart the computer and see if your problem is resolved.
I hope this help.

What do you expect this to do:
public void main(String[] args){
     Polynomial main = new Polynomial();
     Polynomial(polyVar, coefsAndDegs);
          }Or this:
if (polyVar < ' || polyVar > 'z')

Cannot resolve symbol Scanner

Hi all,
i am using the Scanner class, while compiling i got an error cannot resolve the symbol Scanner. i checked my j.dk version also and it's 1.6
syntax:
File file = new File(fileName);
Scanner scanner = new Scanner(file);
error:
TextScanner.java:10: cannot resolve symbol
symbol : class Scanner
location: class TextScanner
Scanner scanner = new Scanner(file);
java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing).
any help is appreciated.

i have already imported that class.
C:\Testing\junk\src>javac -d ..\classes forums\java\sun\Test.java
forums\java\sun\Test.java:14: cannot find symbol
symbol : class Scanner
location: class forums.java.sun.Test
Scanner tester = new Scanner(System.in);
^This is the error I got without the import statement. Notice that it is eeriely similar to the error you received.
Adding the above import fixed my problem. Make sure you are saving the file before trying to compile it, and that you are not compiling an older version.

EDIT: well, that would do it also!

Error when compiling cannot resolve symbol

I am kind of new to java please take a look into this code. I am getting this error cannot resolve the symbol.
this is the first class I saved under folder called javapractice as t1. I don't get any error message when I compile this, but when I compile the second class I got the error message.It would be appreciated if someone can help. thanks
package javapractice;
public class t1{
double a;
double b;
double c;
t1(double ax){
a = ax;
b = 0;
c = 0;
this is the second class also I saved as t2 under javapractice folder. when I compile this class I got the error cannot resolve the name.
package javapractice;
public class t2 {
public static void main(String args[]) {
t1 d = new t1();
d.a = 3;
System.out.println(d.a);
System.out.println(d.b);
System.out.println(d.c);

The problem ist1 d = new t1();You need to pass a double param. to the constructor of t1t1 d = new t1((double)10.0);

Cannot invoke the APIs defined in Servlet 2.4 after installing the TOMCAT5

I have no idea why I still cannot invoke the API like request.getRemotePort() and response.setCharacterEncoding() API after I upgraded to TOMCAT 5.0.
I have included the servlet-api.jar provided with the TOMCAT 5.0 in the class path, but the compiler still cannot resolve the symbols (the above APIs)...
How can I do?

i also encounter this problem, i add severlet2.4 that jar file, but still same wrong message, finally , i found cause, it is because if you also add compile path of j2ee 1.3, that is confliction, so get rid of j2ee 1.3 or download new version of j2ee that will ok

GetPort() returns "cannot resolve symbol" error ???

The bugs database indicate that some errors were fixed with HttpConnection.getPort() and with URL.getPort().
However when I tried to implement a DataSourceServer class , I get following error when compiling :

Hi !
Okay, but I am not using HttpConnection.
I am using the getPort() method from the default java.lang.Object ?
I have tried importing java.net.*; but nope, didn't compile properly either.

Cannot resolve symbol-- data access problem

hi, everyone, i am new to java... thx for helping me.
i have two files
1) dls.java
2) SliderDemo.java
in the dls.java i have the following coding:
JPanel slider = new SliderDemo(this);
slider.framesPerSecond(0);
and in the SliderDemo.java i have following coding:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class SliderDemo extends JPanel implements ActionListener {
//This label uses ImageIcon to show the doggy pictures.
JLabel picture;
dls mydls;
JSlider framesPerSecond;
int i;
public SliderDemo(dls mydls) {
this.mydls = mydls;
framesPerSecond = new JSlider(JSlider.HORIZONTAL, -10, 10, 0);
framesPerSecond.addChangeListener(new SliderListener());
//Turn on labels at major tick marks.
framesPerSecond.setMajorTickSpacing(10);
framesPerSecond.setMinorTickSpacing(1);
framesPerSecond.setPaintTicks(true);
framesPerSecond.setPaintLabels(true);
framesPerSecond.setBorder( BorderFactory.createEmptyBorder(0,0,10,0));
.....etc
when i compile the dls.java
it told me cannot resolve symbol , framePerSecond...
help!!!why i can't resolve the symbol?
thx all experts.
yours,
Terry

cannot resolve symbol , framePerSecondPerhaps because you declared a variable whose name is "framesPerSecond" and then you tried to use "framePerSecond" instead of that?

ToArray error: cannot resolve symbol

Hi ther,
I am getting errors on the line:
newArray = (char[]) newArrayList.toArray(new char[newArrayList.size()]);
I am getting the following error:
vowelProcess.java:176: cannot resolve sybmol
Symbol : method toArray (char[])
Location : class java.util.ArrayList
I cant see what I am doing wrong. I have also tried the following:
newArray = newArrayList.toCharArray();
But get a similar error. Here is the entire method:
public static void getDistinctVowels(char[] vowelArray)
String newArrayValues; //initialise the option entered by user
List newArrayList = new ArrayList();
char[] newArray;
boolean aValue = false;
boolean eValue = false;
boolean iValue = false;
boolean oValue = false;
boolean uValue = false;
for(int i=0; i < vowelArray.length; i++){
     if (vowelArray[i] == 'a')
          aValue = true;
     if (vowelArray[i] == 'e')
          eValue = true;
     if (vowelArray[i] == 'i')
          iValue = true;
     if (vowelArray[i] == 'o')
          oValue = true;
     if (vowelArray[i] == 'u')
          uValue = true;
     } // end of for
if (aValue == true)
          newArrayList.add(new char['a']);
if (eValue == true)
          newArrayList.add(new char['e']);
if (iValue == true)
          newArrayList.add(new char['i']);
if (oValue == true)
          newArrayList.add(new char['o']);
if (uValue == true)
          newArrayList.add(new char['u']);
if (newArrayList.size() > 0)
          newArray = (char[])newArrayList.toArray(new char[newArrayList.size()]);
     String contentsOfNewArray = "";
     for(int i=0; i < newArray.length; i++) {
          contentsOfNewArray = contentsOfNewArray + newArray;
     } // end of for
System.out.print("The contents of the new array are: " + contentsOfNewArray);
     else
          System.out.print("No values were entered.");
} //getDistinctVowels
} //vowelProcess

one more question on this:
If I loop through this array and print out the contents, I do not get the character value (should be a,e,i or u) but some other interpretation: "[C@6b97fd" instead of "a"
here is the code:
char[][] newArray = (char[][]) newArrayList.toArray(new char[newArrayList.size()][1]);
System.out.println("The contents of the new array are: ");
     for(int i=0; i < newArray.length; i++) {
          System.out.println("Test: " + (char[])newArray);
     } // end of for
I have also tried:
System.out.println("Test: " + newArray[i]);
or
System.out.println("Test: " + newArray[i][0]);
or
System.out.println("Test: " + newArray[i][1]);
thanks again.
