    Default comparison between 3 dates :

    I need to return the boolean value based on the below condition. the calculate the date between from date , current date , to date and return the date basd on condition
    fromdate(1st) -------currentdate(2nd)---------todate(3rd)

    fromdate= before date/null
    currentdate= system date
    todate= afterdate/null

    1 fromdate and todate is not null and current date is between fromdate and todate ,then it returns true
    2.fromdate not null and fromdate <= currentdate and todate is null ,then it returns true
    3.fromdate null and currentdate <= todate and todate is not null, it returns true
    4.fromdate =null and todate =null , it returns false

    the code i had written
    ************************************************** ***********************************
    if (fromdate!=null && todate!=null && fromdate.compareTo(currentDate)<0 && todate.compareTo(currentDate)>0)
    {return true;}
    if else(fromdate!=null && fromdate.compareTo(currentDate)<0 && todate=null){return true;}
    if else(todate !=null && todate.compareTo(currentDate)>0 && fromdate=null){return true;}
    ifelse (fromdate==null && todate ==null) {return false;}
    else{return false;}
    ************************************************** **********************************

    Please copy the full text of the error message and paste it here. It has important info about the error.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.

    BTW What you've posted is NOT valid java code. There is no if else
    If you don't understand my answer, don't ignore it, ask a question.
