Re: [ vuZs.net ] CS506 Answer

Thanks Bhai 

Please confirm the answer is true:

Write down the code for a method of ResultMetaData object (rs) to return the database type name of second column

Solution 

An object that can be used to get information about the types and properties of the columns in a ResultSet object. The following code fragment creates the ResultSet object rs, creates the ResultSetMetaData object rsmd, and uses rsmd to find out how many columns rs has and whether the first column in rs can be used in a WHERE clause.

 

ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");

     ResultSetMetaData rsmd = rs.getMetaData();

     int numberOfColumns = rsmd.getColumnCount();

     boolean b = rsmd.isSearchable(1);

Right Answer is : False

Rational:

Purpose of declaring a method final is that it is not overridden by
sub-classes. So its possible that a method can be final while its class is not.

for example:

public class MyClass {
 public final void myFinalMethod() {...}
}

A method can not be made final until whole class is made final.
