Preface

This module is one in a collection of modules on Java Generics designed for teaching ITSE2317 - Java Programming (Intermediate) at Austin Community College in Austin, TX.

This and future modules in this series will be based on the Generics (Updated) section of The Java Tutorials from Oracle. (In the event that these links become broken, you should have no difficulty finding the Oracle material with an online search.)

You will find the learning resources for this module on the Oracle site at:

This module contains review questions and answers keyed to the material in the above document.

Once you study that material, you should be able to answer the review questions in this module.

Once you complete your study of all the material on generics , you should be able to answer the review questions at Questions and Exercises on the Oracle site.

The questions and the answers in this module are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

Questions

Question 1 .

True or False: Generic methods are methods that introduce their own type parameters.

Answer 1

Question 2

True or False: Defining a generic method is similar to declaring a generic type. The type parameter's scope is limited to the class in which it is declared.

Answer 2

Question 3

True or False: Generic methods may be either static or non-static.

Answer 3

Question 4

True or False: Generic class constructors are not allowed.

Answer 4

Question 5

Design and write a class named A05Foo which, when combined with the class defined in Listing 1 will compile, run, and produce the output shown in Figure 1 .

Listing 1 - Question 5.
/*File Q05.java ************************************************/public class Q05{public static void main(String[] args){A05Foo fooA = new A05Foo(); 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 Q05//=============================================//
Figure 1 - Question 5.
abcd efgh abcd 500500 abcd

Answer 5

Question 6

Design and write a class named A06Foo which, when combined with the class defined in Listing 2 will compile, run, and produce the output shown in Figure 2 .

Listing 2 - Question 6.
/*File Q06.java ************************************************/public class Q06{public static void main(String[] args){A06Foo<String>fooA = new A06Foo<>(); fooA.set("_ijklm");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 Q06 //=============================================//

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
