Question 10

The code shown in Listing 4 will not compile and run successfully. Without using a cast operator, what changes can you make to theclass named Q10 to cause the program to compile and run successfully and to produce the current time in milliseconds?

Listing 4 - Question 10.
/*File Q10.java ************************************************/import java.util.*; public class Q10{ArrayList var1 = new ArrayList();void runIt(){ var1.add(new Date());//Note the required cast in the following // statement.System.out.println( (var1.get(0)).getTime());}//runIt public static void main(String[]args){ new Q10().runIt();}//end main}//end class Q10 //=============================================//

Answer 10

Question 11

True or False: Using Java v1.7, even with the empty angle brackets shown in the instantiation of the ArrayList object in Listing 5 , the program in Listing 5 will compile and run successfully with no notes, warnings, errors, or othercomplaints from the compiler. The program will produce an output similar to that shown in Figure 3 .

Listing 5 - Question 11.
/*File Q11.java ************************************************/import java.util.*; public class Q11{ArrayList<Date>var1 = new ArrayList<>(); void runIt(){var1.add(new Date()); //Note the required cast in the following// statement. System.out.println((var1.get(0)).getTime()); }//runItpublic static void main(String[] args){new Q11().runIt(); }//end main}//end class Q11//=============================================//

Answer 11

Question 12

True or False: The program shown in Listing 6 will compile and run successfully producing an output similar to that shown in Figure 4 .

Listing 6 - Question 12.
/*File Q12.java ************************************************/import java.util.*; public class Q12{ArrayList<Date>var1 = new ArrayList<Date>();void runIt(){ var1.add("abcd");System.out.println(var1.get(0).getTime()); }//end runItpublic static void main(String[] args){new Q12().runIt(); }//end main}//end class Q12 //=============================================//

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
