Expert Solution & Answer
Chapter 24, Problem 20RE
Explanation of Solution
Matching the given error messages:
Consider the below command:
java -classpath derby.jar;. TestDB
When executing the above command, the possible error messages are matched with its corresponding error conditions as follows:
Usage: java [-options] class [args...]
The above error message can occur when the “derby.jar” and “.” does not contain a colon “:” when running the command on the operating systems such as Linus, UNIX, or Mac OSX.
- Suppose if we run Linux, UNIX, or Mac OSX, then it should have been separated by a colon (:) but not a semicolon as a path separator, so that the above error can be avoided.
Therefore, the given error message is matches with the error condition “derby.jar and . should have been separated by a colon on this
Exception in thread “main” java.sql.SQLException: No suitable driver found for jdbc:derby:BigJavaDB;create=true
The above error message can occur when there is no suitable driver found for the connection.
- When we run a java database program, the “bin” folder should contain all the required “JAR” files, so that, the above error can be avoided.
Therefore, the given error message matches with the error condition “The derby.jar file was not present in the current directory.”
Exception in thread “main” java.lang. NoClassDefFoundError: TestDB
The above error message can occur when there is no class definition found for the program.
- When we run a Java database program the required class files should be present in the JDK bin directory so that the above error can be avoided.
Therefore, the given error message matches with the error condition “The TestDB.class file was not present in the current directory”
Exception in thread “main” java...

Objective:
1. Implement a custom Vector class in C++ that manages dynamic memory efficiently.
2. Demonstrate an understanding of the Big Five by managing deep copies, move
semantics, and resource cleanup.
3. Explore the performance trade-offs between heap and stack allocation.
Task Description:
Part 1: Custom Vector Implementation
1. Create a Vector class that manages a dynamically allocated array.
。 Member Variables:
°
T✶ data; // Dynamically allocated array for
storage.
std::size_t size; // Number of elements currently
in the vector.
std::size_t capacity; // Maximum number of
elements before reallocation is required.
2. Implement the following core member functions:
Default Constructor: Initialize an empty vector with no allocated storage.
。 Destructor: Free any dynamically allocated memory.
。 Copy Constructor: Perform a deep copy of the data array.
。 Copy Assignment Operator: Free existing resources and perform a deep
copy.
Move Constructor: Transfer ownership of the data array…
2.68♦♦
Write code for a function with the following prototype:
* Mask with least signficant n bits set to 1
* Examples: n = 6 -> 0x3F, n = 17-> 0x1FFFF
* Assume 1 <= n <= w
int lower_one_mask (int n);
Your function should follow the bit-level integer coding rules
Be careful of the case n = W.
Hi-Volt Components
You are the IT manager at Hi-Voltage Components, a medium-sized firm that makes specialized circuit
boards. Hi-Voltage's largest customer, Green Industries, recently installed a computerized purchasing sys-
tem. If Hi-Voltage connects to the purchasing system, Green Industries will be able to submit purchase
orders electronically. Although Hi-Voltage has a computerized accounting system, that system is not
capable of handling EDI.
Tasks
1. What options does Hi-Voltage have for developing a system to connect with Green Industries' pur-
chasing system?
2. What terms or concepts describe the proposed computer-to-computer relationship between
Hi-Voltage and Green Industries?
why not?
3. Would Hi-Voltage's proposed new system be a transaction processing system? Why or
4. Before Hi-Voltage makes a final decision, should the company consider an ERP system? Why or
why not?

- Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character.
