Question
Chapter 10, Problem 1RQ
Program Plan Intro
To find the correct option that can be used as a reliable way to find which class is a base class and which is a derived class.
Expert Solution & Answer
Program Description Answer
b. try saying the two class names together.
Explanation of Solution
Explanation:
Classes can be derived from other classes in Java, as in other object-oriented
A reliable way that will help to find which of the two classes is the base class and which is a subclass is by try saying the two class names together.
By saying the names of both base class and derived class, one should check which class is containing more generalized features and which is not. A class that contains more generalized features should be considered as the base class and the other one should be considered as the derived one.
For example: Consider two classes Birds and Pigeon. If we call the names of both, surely, the Birds class will contain more generalized features instead of the Pigeon class. So, the Birds class will be a base class and the Pigeon class will be the derived one.
Conclusion:
Therefore, the correct option is option b. try saying the two class names together.

In recent years, growing demand has exposed the limitations of their fragmented processes and outdated systems. Different departments manage production schedules, raw material requirements, and finished goods inventory using a patchwork of spreadsheets and older software tools. These silos create inconsistent data, errors in stock levels, delivery delays, and customer dissatisfaction. Green Fields plans to implement an Integrated Inventory Management System to centralise production, procurement, inventory, and sales data to address these challenges. This technology aims to provide real-time visibility into stock levels, automate reorder points, and generate analytical dashboards for managers at both operational and strategic levels. Ultimately, the new system will streamline workflows, reduce…arrow_forward. Differentiate between continuous and discrete systems.

Word FrequencyWrite a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.arrow_forward3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.arrow_forward

Testing Hint: We be exact on the format of the number when testing this method. Make sure you think about how to convert 33 to 033 or numbers like that when setting your string format.

Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer. You will need to know the hex values of the following characters:arrow_forwardA ROP (Return-Oriented Programming) attack can be used to execute arbitrary instructions by chaining together small pieces of code called "gadgets." Your goal is to create a stack layout for a ROP attack that calls a function located at '0x4018bd3'. Below is the assembly code for the function 'getbuf', which allocates 8 bytes of stack space for a 'char' array. This array is then passed to the 'gets' function. Additionally, you are provided with five useful gadgets and their addresses. Use these gadgets to construct the stack layout. Assembly for getbuf 1 getbuf: 2 sub $8, %rsp 3 mov %rsp, %rdi 4 call gets 56 add $8, %rsp ret #Allocate 8 bytes for buffer #Load buffer address into %rdi #Call gets with buffer #Restore the stack pointer #Return to caller.
