How does the getConnection(....) method of DriverManager class return a Connection object?Connection is an interface and you cannot create object of an interface.Ditto for Statement and ResultSet..Plz explain

You can return a class which implements the interface and catch it as an interface.
interface InterOne{
//...methods
}
public class AnyClass implements InterOne {
public InterOne createCopy(){

return new AnyClass();
}

public AnyClass createAnotherCopy(){

return new AnyClass();
}
}
class AnyTestClass (){
public static void main(String [] args){
AnyClass Test1 = new AnyClass();

InterOne sample = Test1.createCopy();
InterOne anotherSample = Test1.createAnotherCopy();
}
}

And same stuff goes for the abstract class Change Interface declaration to an abstract class
