Indentifiers/Resolving Symbols
Hello Everyone,
I'm trying to write an app that reads in two integers and determines and prints if the first is a multiple of the second while utilizing the modulus operator.
When I run the compiler, receive the following errors:
C:\jdk1.3.1\bin>javac Filename.java
Filename.java:12: <identifier> expected
in = new ( System.in );
^
Filename.java:12: '(' or '[' expected
in = new ( System.in );
^
Filename.java:12: cannot resolve symbol
symbol : variable in
location: class Filename
in = new ( System.in );
^
Filename.java:16: cannot resolve symbol
symbol : variable in
location: class Filename
int num = in.readInt();
Any indication of where I'm going wrong would be greatly appreciated!!
Below is the actual code:
public class Filename
public static void main( String[] args )
Number in = new Number ( System.in );
System.out.print( "Enter a number: " );
int num = in.readInt();
if ( num%2 == 0 )
System.out.println( "This number is an integer!" );
else
System.out.println( "This number is not an integer :-(" );
Dear JenniferP42,
I am confused with your code, but I have written a similar one.

try{
System.out.print( "Enter a number: " );
//convert tthe input stream to a buffered reader
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String str="";
int input=0;
int firstNum=0;
//type end to end program
while(!((str=br.readLine()).equals("end"))) {
System.out.println("String typed="+str);
// check the string typed whether it is an int remember int is form -2(power32) to 2(power32)-1
// if you just want digits user checkDigit() function which I wrote below but remember a number to big will overflow the int
// you might want to restrict the user input(best choice) or use long instead(still face overflow)
if(checkInteger(str)) {
System.out.println("This is a number");
input++;
//if it is the first number keep it in memory
if(input==1) {
firstNum=Integer.parseInt(str);
//if the second one is inputed then do checkAnswer function

System.exit(0);

Visual Studio 2012 cannot resolve symbol or Errors control is not a member of class
Visual Studio 2012 Web Site Project (Note not a Web application, so there are not Designer.vb files) > Site works perfectly fine and using IIS and attaching to IIS to debug code.
However, if I try to build the site inside of Visual Studio I am getting lots of Errors ‘pnlName’ is not a member of ‘Page_Name’ In the code behind I am getting errors ‘Cannot resolve symbol ‘pnlName’
.ascx Page
<li style="margin-right:0;" id="pnlName" runat="server"><a href="/cart" title="Checkout" class="global-checkout">Checkout</a></li>
.ascx.vb page
Me.pnlName.Attributes.Remove("style")
I have cleaned, rebuild and nothing gets rid of these errors, but again the site works as designed, but I would like to launch and debug inside of Visual Studio.

http://moojjoo.blogspot.comCor,
What I am stating is this is a solution using the Web Site Project instead of a
Web Application Project.
Web Site projects do not require Designer.vb files, Web Application Projects add Designer.vb files in the solution.
Background: I have been hired to support a very successful e-commerce site that was built by a 3rd party vendor (I had no input on the contract or specification, because I would have went with
MVC). The site works 100% correctly, however from my 2003 - 2015 experience with Visual Studio and Web Development being in Web Forms and MVC I have always built ASP.NET Solutions using the Web Application Project Templates, which compiles the code down
to .dlls.
A Web Site project does not compile the code, but simply uses the .vb files and they have to be migrated to the server with the .aspx files. http://msdn.microsoft.com/en-us/library/dd547590%28v=vs.110%29.aspx
Currently the only way I can debug this Solution is to attach to the w3wp.exe process running locally on my work station.
The Solution is comprised of two Web Sites, which I cannot get it to compile because of the following errors -
'webServerControlName' is not a member of '(Protected Code Behind Class Name)' I am reaching out to the MSDN community to see if anyone has experienced this issue with
Web Site Projects.
I hope that clears up the Project Type question.

Getting error message Cannot Resolve Symbol when trying to compile a class
Hello All -
I am getting an error message cannot resolve symbol while trying to compile a java class that calls another java class in the same package. The called class compiles fine, but the calling class generates
the following error message:

I am using Sun JDK Version 1.3.0_02" and Apache/Tomcat 4.0. Both the calling and the called class are in the same directory.
Any help would be greatly appreciated.
tnx..
addiIs ConnectionPool in this "cal" package as well as PooledConnection? From the directory you are compiling from it appears that it is. If it is, then you are compiling it incorrectly. To compile ConnectionPool (and PooledConnection similarly), you must change the current directory to the one that contains cal and type
javac cal/ConnectionPool. -
Missing method body and cannot resolve symbol
I keep getting these two errors when trying to compile. I know that I need to call my fibonacci and factorial functions from the main function. Is this why I am getting the missing method body error? How do I correct this?
Am I getting the cannot resolve symbol because I have to set the num and fact to equal something?
Thanks
public class Firstassignment
public static void main(String[]args)
System.out.println();
public static void fibonacci(String[]args);
int even=1;
int odd=1;
while (odd<=100);
System.out.println(even);
int temp = even;
even = odd;
odd = odd + temp;
public static void factorial (String[]args);
for (int count=1;
count<=num;
count++);
fact = fact * count;
outputbox.printLine("Factorial of" + num + "is" + fact);Hey... :o)
the problem is that you've put semicolons at the end of the function signature, like this:
public static void fibonacci(String[]args);
}that should happen only when the function is abstract... so ur function should actually look like this:
public static void fibonacci(String[]args)
}also, i think you've missed out on the declarations (like what are fact and num??).... -
"cannot resolve symbol" in a Timer !!!Please Help!!!
I am doing a program for a class which involves timers. I am using JCreator and when i try to construct a new timer, the compiler points to the "new" in the line:

I've tried importing java.*
I've also checked my classpath.
Any ideas?Try taking the import statement out of the comment block; that might help

Cannot resolve symbol: class OracleDriver
Attempting to compile a servlet on Apache Server using same jdeveloper jdbc libraries:
classes12.jar & nls_charset12.jar
Error message:
$compilejava2.sh ProdJobs
ProdJobs.java:361: cannot resolve symbol
symbol : class OracleDriver
location: package driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Am I missing something else?
JeffreyEnter this code into your program and then put the Oracle jar file that contains the driver in your run-time classpath.
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
catch(ClassNotFoundException cnfe) {
// driver not found
}The effect of this is that the classloader will load the Oracle driver for you then call it's static initiailizer that does a bunch of magic that results in the Java runtime knowing that there's a JDBC driver out there.
It is a little weird - but that's the way it works. -

Cannot resolve symbol class graphics
does anyone know what the error
cannot resolve symbol class graphics means?
with this code i can't seem to call the graphics method to draw the line....any reason why?

x2 = Integer.parseInt(JOptionPane.showInputDialog("Enter x2:"));
y2 = Integer.parseInt(JOptionPane.showInputDialog("Enter y2:"));
repaint();
}well the exact error message is ...by the way now that i think about it
if the graphics method shoudl not be part of the JFrame class then what method would i use to draw 2D Graphics?

Cannot resolve symbol error even with class imported
Hi
I'm trying to print out a java.version system property but keep getting a
cannot resolve symbol error

I've looked at the API and getProperty() is a method of lang.System
Can anyone throw any light?
thanks

It compiles but I now get a runtime error
Exception in thread "main"
java.lang.NoClassDefFoundError:PropertiesTest
What do you reckon is the problem?
thanks
java -cp .;<any other directories or jars>
YourClassNameYou get a NoClassDefFoundError message because the
JVM (Java Virtual Machine) can't find your class. The
way to remedy this is to ensure that your class is
included in the classpath. The example assumes that
you are in the same directory as the class you're
trying to run.I know it's a bad habit but I've put this file (PropertiesTest.java) and the compiled class (PropertiesTest.class) both in my bin folder which contains the javac compiler -
