Chapter 11, Problem 1.1SRE
Program Plan Intro
Program Plan
To list the types of exceptions that may occur during compiling or run time of a java program.
Expert Solution & Answer
Program Description Answer
ClassCastException, NullPointerException, ArithmeticException, IndexOutOfBoundsException, and IOException are the five types of exceptions that are commonly occurring during the program execution.
Explanation of Solution
In a high-level
Run Time Exceptions (or Unchecked Exceptions)
- ClassCastException- this type of exception occurs when a programmer tries to cast an object of the parent class to its child class type or to cast an object of one class to an object of another class that is not extending the former.
- NullPointerException- occurs when a method calls the instance of an object which is null or tries to access, modify, to access the length of a null value. If a programmer wants to access elements of an array without initializing it then NullPointerException is thrown.
- ArithmeticException- occurs when an exceptional condition occurs while doing an arithmetic operation such as Divide by Zero.
- IndexOutOfBoundsException- occurs when an index of a string or an array is negative or greater than the size of an object.
- IOException- occurs when an interrupt arises during input-output operation or it is failed.

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;

do {
root old root;
root (root_old+number/root_old)/2;
while (Math.abs (root_old-root)>1.0E-6);
return root;
}

- Write a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values.
