                        tasks.addItemAt(new Task("", "", ""), e.rowIndex);

Venktesan,
You are trying compare String and int..! which is not possible try to case the txtIn.text to int using parseInt(txtIn.text).
ORIGINAL:
if(txtIn.text != ADD_TASK).---->error : Comparison between a value with static type String and a possibly unrelated type int
                    tasks.addItemAt(new Task(txtIn.text, 0, ""), e.rowIndex);----> error:Implicit coercion of a value of type String to an unrelated type int.
EDITED:
if(parseInt(txtIn.text) != ADD_TASK).---->error : Comparison between a value with static type String and a possibly unrelated type int
                    tasks.addItemAt(new Task(parseInt(txtIn.text), 0, ""), e.rowIndex);----> error:Implicit coercion of a value of type String to an unrelated type int.
