Retrieve single result with 2 columns in oracle

Question

Do we have any function in oracle do this scenario.

There are 2 columns in table col1, col2.

col1 either has 'Y' or 'N' or NULL

col2 eitehr has 'Y' or 'N' or NULL 

But always only one of the column has value 'Y'.

So , i want to check first col1 whether it has 'Y' ,if it has i want a string "COL1 found" ,if col2 has 'Y' i want a string "COL2 found". Is it possible with NVL2 and Decode function. With one column ,i can able to do that. But here i have to check 2 columns .Please note that i want a result in single row.
