"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:
Timer T1=new Timer(interval, ActionListener);
^
This is what it looks like and the error reads: cannot resolve symbol; constructor Timer.
please tell me if yiou have any information or suggestions as to how this error might be remedied.
Sure, here it is:

Cannot sync for the first time, please help
I'm using 3-G4 units, two will sync 1 will not. The one that will not is a G3 B|W unit that I upgraded to a G4 Processor 500 MHz After giving this unit a different name than the others,I can see all three computers in the isync window but when I press sync it starts but stops right away not completing the sync.
G3-B|W Upgrade to G4 Mac OS X (10.3.9) 500MHz proc,650HD,It has died. Like a million times. It won't stay recognized long enough to charge. do you know what I mean? Meaning, I'll get the little icon that means there's very low battery, and it's charging, then after a few minutes, it will say "no battery power, connect ipod to power"
And I've tried an adapter that lets you plug it into a wall, and that doesn't work either. I do have an ipod clock radio, tho with a dock... I'll try that tomorrow. If that doesn't work,I might buy her one, because I feel responsible for this. But you don't care about that XD
Thanks for the help -
HELP PLEASE Cannot resolve symbol error
Only just started to atempt simple java programs and this same error keeps appearing. code i am using is:
import java.io.*;

System.out.printIn ("Input a number");
num1= Course_io.readInt();
System.out.printIn ("Input another number");
num2= Course_io.readInt();
sum= num2 - num1;

Need help - method call error cannot resolve symbol
My code compiles fine but I continue to receive a method call error "cannot resolve symbol - variable superman" - can't figure out why. Here is my code:
public static String caesar(String message, int shift)
{ [b]String result = "";
for(int i = 0; i < message.length(); ++i)
{ [b]char newChar = message.charAt(i + shift);
result += newChar;
return result.toUpperCase();
I entered "superman" for message and "3" for the shift. Can someone please help? Thanks!Your post worked great - especially since it made me realize I was going about it all wrong! I was attempting to convert "superman" to "vxshupdq" - basically a cipher shift starting at index 0 and shifting it 3 character values which would result in s changing to v. I restructured my code:
public static String caesar(String message, int shift)
{ [b]String result = "";
for(int i = 0; i < message.length(); ++i)
{ [b]char newChar = message.charAt(i);
result += (newChar + shift) % message.length();
return result.toUpperCase();
But it's displaying the result as a "60305041". How can I get it to display the actual characters? -
Help!!! error: cannot resolve symbol
can anyone tell me how to solve the following problem
thank you
cannot resolve symbol
symbol : method decode (java.lang.String)
location: class java.lang.Short
Short psmShort = Short.decode(psmString);
^
Long bdAddrLong = Long.decode("0x" + bdAddrString);
^that is because these methods does not exist. What you can use instead is parseShort(String) or parseLong.
Maybe reading the javadoc could help you next time ;-)

"cannot resolve symbol" help..
Here is a very short and simpel program that won't compile after I reinstalled java on my computer.
import java.lang.Math.*;
import java.awt.*;
public class PiTest extends Frame {
public static void main(String[] p){
System.out.println("testing MATHs");
System.out.println(""+sin(10));
I get the following error:
PiTest.java:8: cannot resolve symbol
symbol : method sin (int)
location: class PiTest
System.out.println(""+sin(10));
^
[total 1553ms]
1 error
Why doesn't the compiler recognise the sine function? I have set my classpath to c:\j2sdk1.4.1_01\lib.
I don't know what I'm doing wrong...Replace sin(10) with Math.sin(10), it should work.
import java.lang.Math.*;
import java.awt.*;
public class PiTest extends Frame {
public static void main(String[] p){
System.out.println("testing MATHs");
//System.out.println(""+sin(10));

BufferedReader cannot resolve symbol
Hi,
I need some help with a java program which reads xml files to a specified location, running it on a UNIX machine using Java 1.4.1. I modified the code to include the BufferedReader class, but it keeps complaining about not being able to resolve symbol at line 50 & 53. Any help here would be appreciated, since I'm a newbie.

Edited by: nickmills on Aug 31, 2008 5:05 PMFirst, you only need to create the FileInputStream once. Then that's what you pass to the InputStreamReader constructor. Your code for reading from the BufferedReader is also wrong.FileInputStream fstream = new FileInputStream(outputLocation+filename);
// FileInputStream bis = new FileInputStream(fstream); <-- remove this line
BufferedReader in = new BufferedReader(new InputStreamReader(fstream));
// available() doesn't do what you think it does; forget about it.
// Here's the standard way to use a BufferedReader
String line = null;
while ((line = in.readLine()) != null)
// process 'line'
} There are probably other errors in the code, but reading all that unformatted code is too much of a hassle. In future, please use {code} tags when posting source code. -
Cannot resolve symbol when the classes are in the same package
i have one interface and two classes all in the same package. am getting " cannot resolve symbol", when the code refers to the interface or the class .
the package name is collections.impl and
the directory i used to store all the java files:
c:\jdk\bin\collections\impl.
isthere any othe option other than compiling all the files from the comand line at the same time?
please help - i m new to java.If you have:
I.java:
package some;
public interface I {
void method();
}A.java:
package some;
public class A implements I {
public void method() {
new B();
}B.java:
package some;
public class B implements I {
public void method() {
new A();
}in c:/temp/some for example
you can compile your files with
javac c:/temp/some/*.java
It seems that you have errors in your code.
Recheck it twice or use NetBeans IDE(http://www.netbeans.org) it will do this for you ;)
