can not resolve symbol

[mamathareddy]

hi all,
when i am trying to implement an interface,at compile time when i am trying to compile the implementation class i am getting an error like can not resolve the symbol.what may be the problem?please send it as soon as possible

ex:interface:

import java.rmi.*;
public interface MyRemote extends Remote
{
public int add(int i,int j)throws RemoteException;
public int sub(int i,int j)throws RemoteException;
}

implementation class:

import java.rmi.*;
import java.rmi.server.*;
public class MyImpl implements MyRemote
{
public MyImpl() throws RemoteException{
}
public int add(int i,int j)
{
System.out.println("In add method of MyImpl");
return(i+j);
}
public int sub(int i,int j)
{
System.out.println("In sub method of MyImpl");
return(i-j);
}
};

};

1.) Use code tags when posting code
2.) What's the full error message you got?

Hi,
Compiler will be definitely pointing to the line exactly where u r getting error. And It will also giving u the name of the symbol, which it is not able to resolve.....So go to that line and find that symbol.... Either u have mistype the symbol name or u haven't define that symbol at all.
Check it again... or send ur error.

Hi mamathareddy! Welcome to TSDN!
I copied your classes and could not recreate the error - however, possibly my main method is different:

public static void main(String[] args) {
    try
    {
        MyImpl impl = new MyImpl();
        System.out.println("Add: " + impl.add(23, 42));
        System.out.println("Sub: " + impl.sub(42, 23));
    }
    catch(Exception e)
    {
        System.err.println(e);
    }
}
 

Normally ... cannot be resolved indicates, that you did something like

impl = new MyImpl();
 

Without defining impl with MyImpl impl.
