Chapter 5, Problem 1TC
Explanation of Solution
Given: A Lenovo IdeaPad N580 laptop with a faulty hard drive and a Toshiba MK8009GAH 80-GB 4200-RPM drive
To find: Whether the faulty drive can be replaced with the Toshiba drive or not.
Solution:
A Lenovo IdeaPad N580 has 2.5-inch SATA hard drive, whereas a Toshiba MK8009GAH has a form factor of 1.8 inches and has a UDMA interface.
Hence, option (d) is correct as neither the form factor nor the interface matches.

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
// Method that calculates the square root of double variables
public static double myRoot(double number) {
double root;
root number/2;
double root_old;
do {
root old root;
root (root_old+number/root_old)/2;
while (Math.abs (root_old-root)>1.0E-6);
return root;
}
}

The Javaprogram does the following steps:a) The program must use single-dimensional arrays to store the studentinformation such as Student ID, Name and Major.b) The program asks the user to provide the number of students.c) The program asks the user to enter the Student IDs for the number of studentsand stores them.d) The program asks the user to enter the corresponding names for the numberof students and stores them.e) The program then asks the user to provide the corresponding major for thestudents and stores them.f) The program then should display the following options:1.
