Chapter 16.1, Problem 3STE
Program Plan Intro
Exception:
An exception is a problem that creates during the execution of a program; it offers a method to transfer control from one part to another part of a program.
An exception handling is created by using the following three keywords such as try, catch and throw.
- The “try” block have the program for the basic
algorithm that says the computer what to do when all goes well. - The “throw” keyword throws an error statement to the “catch” block.
- The “catch” block will catch the exception or handling the exception.
Generally, the compiler executes “try” block. In the “try” block, if the statements cause an exception, it throws an error statement to the “catch” block using the keyword “throw”. The “catch” block then handles the error based upon the type of exception.

Suppose you are asked to test the code below. The code:
public String allocateRoom(int numOfEmps) throws IllegalArgumentException {
if (numOfEmps == 0)
throw new IllegalArgumentException();
if (numOfEmps < 5)
return "Small";
if (numOfEmps < 10)
return "Standard"; return "Large";
}
Throws exception if there are no employees
Returns small up to 5 employees
Returns standard for 5 to 9 employees
Returns large for 10 or more employees
List the minimum amount of test inputs that achieve 100% branch coverage. You need to specify the branch(es) each input covers.
List the minimum amount of test inputs that achieve 100% path coverage. You need to specify the path each input covers.
Explain if executing the test suites above will reveal any defects.
this practice assignment wants me to : Write an application that asks a user to enter an integer. Display a statement that indicates whether the integer is even or odd.
it is saying that i am missing a return statement.
here is my code:
mport java.util.Scanner;
class EvenOdd {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int number;
System.out.println("Enter the integer >>>");
number = input.nextInt();
}
public static boolean isEven(int number) {
if (number % 2 == 0)
System.out.println("The number is even.");
else
System.out.println("The number is odd.");
}
}
Complete the code below according to the instructions below and the example test:
method withdraw throws an exception if amount is greater than balance.
For example:
Test
Result
Account account = new Account("Acct-001","Juan dela Cruz", 5000.0); account.withdraw(5500.0);
System.out.println("Balance: "+account.getBalance());
Insufficient: Insufficient funds.
Balance: 5000.0
Account account = new Account("Acct-001","Juan dela Cruz", 5000.0); account.withdraw(500.0);
System.out.println("Balance: "+account.getBalance());
Balance: 4500.0
Incomplete java code:
public class Account{ private String accntNumber; private String accntName; private double balance; public Account(){} public Account(String num, String name, double bal){ accntNumber = num; accntName = name; balance = bal; } public double getBalance(){ return balance;}}//your class here
