ARRAYINDEXOUTOFBOUNDSEXCEPTION
ArrayIndexOutOfBoundsException
ArrayIndexOutOfBoundsException occurs when the program tries to access the array beyond its size.
Write a program to manipulate array operation by handling ArrayIndexOutOfBoundsException
Create an array of size 100 and assume it as seat array. Get the tickets to be booked from the user and handle any exception that occurs in Main Class. At last display all the tickets booked.
Input and Output format:
The first line of input consists of an integer which corresponds to the number of seats to be booked.
The next n lines of input consist of the integer which corresponds to the seat number. The seat number starts from 1 to 100.
If the exception is thrown, then display the exception with the index number. Else display all the tickets booked
Refer to sample Input and Output for formatting specifications.
[All Texts in bold corresponds to the input and rest are output]
Sample Input and Output 1:
Enter the number of seats to be booked:
5
Enter the seat number 1
23
Enter the seat number 2
42
Enter the seat number 3
65
Enter the seat number 4
81
Enter the seat number 5
100
The seats booked are:
23
42
65
81
100
Sample Input and Output 2:
Enter the number of seats to be booked:
4
Enter the seat number 1
12
Enter the seat number 2
101
java.lang.ArrayIndexOutOfBoundsException: 100

System.out.println(i+1);

System.out.println(e);
}

ARITHMETIC EXCEPTION
Arithmetic Exception
An exception is an unwanted or unexpected event, which occurs during the execution of a program i.e at runtime, it disrupts the normal flow of the program. For example, there are 10 statements in your program and there occurs an exception at statement 5, the rest of the code will not be executed i.e. statement 6 to 10 will not run. If we perform exception handling, the rest of the statement will be executed. That is why we use exception handling.
Write a program to obtain the cost for 'n' days of an item and n as input and calculate the cost per day for the item. In case, zero is given as input for n, an arithmetic exception is thrown, handle the exception and prompt the user accordingly.
Consider a driver class called Main. In the main method, obtain input from the user and store the values in integer type. Handle exception if one occurs.
Input format:
The first line of input is an integer which corresponds to the cost of the item for n days.
The second line of input is an integer which corresponds to the value n.
Output format:
If the value of n is zero throws an exception.
Otherwise, print the integer output which corresponds to the cost per day of the item.
[All text in bold corresponds to the input and rest corresponds to the output]
Sample Input and Output 1:
Enter the cost of the item for n days
100
Enter the value of n
0
java.lang.ArithmeticException: / by zero
Sample Input and Output 2:
Enter the cost of the item for n days
100
Enter the value of n
20
Cost per day of the item is 5
Sample Input and Output 1:
Enter the cost of the item for n days
100
Enter the value of n
0
java.lang.ArithmeticException: / by zero
Sample Input and Output 2:
Enter the cost of the item for n days
100
Enter the value of n
20
Cost per day of the item is 5
