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 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"

Back to Question 8

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//=============================================//

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.

Back to Question 4

Answer 3

True.

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."

Back to Question 2

Answer 1

True.
