    Hi Riyas,

    As we know "IF" is a conditional statement in programming language and it needs boolean values "True" or "1" or any integer value not equal to 0 to perform an action or not perform Action in case of "False" or '0'.

    I think your calculation.CalculateEOSAccrual() is not returning anything Void or returning some string.

    to make it work kindly change your method to return any value.

    if it not boolean. try some thing like this if(calculation.CalculatedEOSAccrual()=="Return Value") .

    Note: "Return Value" is just an example

    You can of course call the method. But you can't have a condition that is based on the return value of a method that doesn't return anything! I'm sure it's clear to you, too.

    If it's not clear, please let us know what is the purpose of your if statement. What should it do? And in what situations should the code execution go inside the if statement and when should it not?

    Please check this article, it will help you understand about conditional statements: en.wikipedia.org/.../Conditional_(computer_programming)

    Hi Riyas,

    That's the problem, you could try to change the method and give it a boolean return.

    But it's all based on your requirement.

    Thanks for you replay sir,

    you're correct, its return type is void so how to ignore that issue ? i want to use that method.

    Any condition in an if statement must be possible to resolve as boolean (true or false).

    You need to go to calculation.CalculateEOSAccrual() and see what's the return type. Perhaps it doesn't return anything (return type is void).

    Hi Riyas,

    What's the return of your CalculateEOSAccrual() method? You should a boolean value in the if statements.
