Why does order matter when catching exceptions?

I had to answer this question with some code:

Suppose I wrote the following method specification:
public void manipulateData ( ) throws java.sql.SQLException, java.sql.SQLDataException

You are writing code for a database program that will use this method and you want to handle each specifically. What should the try/catch clause look like?
You can use no-ops-- empty blocks {}--for the catch clause contents.
We are only interested in the syntax and structure of the statements here.

I answered with this:

try {

} catch(java.sql.SQLException e) {

}
catch(java.sql.SQLDataException e) {

}

He did not accept the answer for this reason:

"Your catch clauses are in the wrong order. Can you explain why the order matters?"

Is he correct in his answer?
