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"

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

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.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments

can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
