Answer:
The only difference is the order of operations between the increment of the variable and the value the operator returns. So basically ++i returns the value after it is incremented, while i++ return the value before it is incremented.
Answer:
runtime error
Explanation:
Based on the information provided within the question it can be said that the line of code "System.out.println(resultSet.getString(1));" would not print out anything and instead would give you a runtime error. This is because there is no resultSet.next() line in your code allowing for the resultSet to start in the first row and move consequently down the rows. Thus giving a runtime error.
