Answer 6

Question 7

Design and write a class named A07Foo which, when combined with the class defined in Listing 3 will compile, run, and produce the output shown in Figure 3 .

Listing 3 - Question 7.
/*File Q07.java ************************************************/public class Q07{public static void main(String[] args){A07Foo<Integer,String>fooA = new A07Foo<>(" ijkl"); fooA.set(new Integer(-300));System.out.println( fooA.cat("abcd "," efgh "));System.out.println( fooA.cat("abcd ",new Integer(500)));System.out.println( fooA.cat(new Integer(500)," abcd "));}//end main }//end class Q07//=============================================//

Answer 7

Question 8

True or False: The syntax for a generic method includes a type parameter, inside angle brackets, and appears after the method's return type

Answer 8



What is the meaning of the following two images?

These images were inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.

Spacer image of a rabbit and a penguin.

This image was also inserted for the purpose of inserting space between the questions and the answers.

Spacer image of a penguin and some houses.


Answer 8

False. The statement should read:

"The syntax for a generic method includes a type parameter, inside angle brackets, and appears before the method's return type"

Answer 7

One possible solution is provided in Listing 4 below.

Listing 4 - Answer 7.
/*File A07Foo.java ************************************************///A generic class public class A07Foo<T3,T4>{ private T3 tC;private T4 tD;//constructor public A07Foo(T4 tD){this.tD = tD; }//end constructor//A set methodpublic void set(T3 tC){ this.tC = tC;}//end cat//A generic concatenation method public<T1,T2>String cat(T1 tA,T2 tB){ return tA.toString() + tB.toString()+ tC.toString() + tD.toString(); }//end cat}//end A07Foo//=============================================//

Answer 6

One possible solution is provided in Listing 5 below.

Listing 5 - Answer 6.
/*File A06Foo.java ************************************************/public class A06Foo<T3>{ private T3 tC;//A set methodpublic void set(T3 tC){ this.tC = tC;}//end cat//A generic concatenation method public<T1,T2>String cat(T1 tA,T2 tB){ return tA.toString() + tB.toString()+ tC.toString(); }//end cat}//end A06Foo//=============================================//

Back to Question 6

Answer 5

One possible solution is provided in Listing 6 below.

Listing 6 - Answer 5.
/*File A05Foo.java ************************************************/public class A05Foo{ //A generic concatenation methodpublic<T1,T2>String cat(T1 tA,T2 tB){ return tA.toString() + tB.toString();}//end cat }//end A05Foo//=============================================//

Back to Question 5

Answer 4

False. Generic class constructors are allowed.

Answer 3


Back to Question 3

Answer 2

False. The statement should read as follows:

"Defining a generic method is similar to declaring a generic type, but the type parameter's scope is limited to the method where it is declared."

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.
