Hi Anji,

Do you mean "Execute anonymous" in workbench?
You can execute your code in workbence: 
Go to Workbench-> utilities->Apex Execute  and there you can put your code to executes it anonymously.

Thanks,
Pratik

i have executed it through  Workbench-> utilities->Apex Execute.
and there i entered

system.debug( '+k');
 but in the output it is showing

Hi Anji,

You can simply execute below code in execute anonymous. You don't need class and constructor in anonymous block:

integer i= 10;
integer j= 20;
integer k = i+j;
system.debug( 'The sum of the i and j is :'  +k);

Thanks,
Pratik

Thank you Pratik.
but my requirement is to access the variable k (integer) from the apex class to workbench..
what i have to write the code in the workbench for that class to access that variable which is inside that apex class.

Thanks and Regards,

Hi Anji,

The problem in your code is just in the System.debug statement.
It should be as follows: 
  
public class firstclass
{
    integer i= 10;
    integer j= 20;
    integer k=i+j;

    public firstclass()
    {
        system.debug('The sum of the i and j is :  '+k);
    }
}

Note the placement of single quotes '  ' in the line. That's how it should be written. 
The sum of the i and j is : is your debug statement that you want to print out, which should be within '  ' and k is the variable whose value you want to print.

After making this change the same lines that you used to execute in Apex Execute should give you the result
  
32.0 APEX_CODE,DEBUG
Execute Anonymous: firstclass ab= new firstclass();
Execute Anonymous: system.debug( '+k');

If this solved your issue kindly mark it as the solution.

Hi Lakshmi, Thankyou for your reply.
Now my requirement is to access that k variable in the Workbench.
so that i have written this code in the workbench as follows,
firstclass abc= new firstclass();
system.debug(' the sum of I  and J is : '+k);

COMPILE ERROR: Variable does not exist: k
LINE: 2 COLUMN: 43
So please kindly tell me how to get the value of k.

Thanks and regards,
anji

Hi Anji,

I don't find any reason why such an error should occur. I tried executing the code.

Hope you have corrected the System.debug statement in your apex class firstclass too and not just in the code snippet executed in workbench.

Thanks & Regards,
Lakshmi.

Apex Class: 
public class firstclass
{
    integer i= 10;
    integer j= 20;
    integer k=i+j;

    public firstclass()
    {
        system.debug('The sum of the i and j is :  '+k);
    }
}

 Code to be executed in Workbench: 
firstclass abc= new firstclass();
You shouldn't be writing the debug statement in the Apex execute area. The variable will ofcourse not be recognized there.

Thanks & Regards,
Lakshmi.
