Textbook Question

Chapter 6, Problem 5E

Consider a class characteristic that will be used in an online dating service to assess how compatible two people are. Its attributes are

description—a string that identifies the characteristic
rating—an integer between 1 and 10 that indicates a person’s desire for this characteristic in another person

a. Write a constructor that sets the description of the characteristic to a given string and sets the rating to zero to indicate that it has not yet been determined.
b. Write a private method isValid (aRating) that returns true if the given rating is valid, that is. is between 1 and 10.
c. Write a method setRating(aRating) that sets the rating to aRating if it is valid.
d. Write a method setRating that reads a rating from the keyboard, insisting that the rating supplied by the user be valid.

Students have asked these similar questions

What does the value of the top variable indicate in this ArrayStack implementation? What will happen if we call pop on this stack? What value will be returned, and what changes will occur in the array and the top variable? 3. If we push the value "echo" onto the stack, where will it be stored in the array, and what will be the new value of top? 4. Explain why index 0 contains the string "alpha" even though top is currently 3. 5. What would the state of the stack look like (values in the array and value of top) after two consecutive pop 0 operations?

Please solve and show all work. Suppose there are four routers between a source and a destination hosts. Ignoring fragmentation, an IP datagram sent from source to destination will travel over how many interfaces? How many forwarding tables will be indexed to move the datagram from the source to the destination?

Please solve and show all work. When a large datagram is fragmented into multiple smaller datagrams, where are these smaller datagrams reassembled into a single large datagram?
