Question
An attempt to convert string to a number type uses which of the following exception? Example- String s=”xyz” int i=Integer.parseInt(s);a) NumberFormatExceptionc) ArrayIndexOutOfBoundd) NullPointerb) AirthmeticException
Solution
The correct answer is a) NumberFormatException. This exception is thrown by the methods that are used to convert a string into a number, such as the method Integer.parseInt(s), when they are unable to convert the string into a number. In the given example, the string "xyz" cannot be converted into a number, so a NumberFormatException would be thrown.

NumberFormatExceptionAnother typical exception that you have probably already encountered is when using a BufferedReader to read input. You must parse the string into different data types, such as integer and double. A NumberFormatException is thrown, for instance, if you attempt to parse a string ("abc") into an integer. In order to handle this NumberFormat error, let's try This issue might arise in our program when getting properties for classes like ItemType. then attempt to control it in this program.Create a class ItemType with the following attribute: "Add appropriate getter and setter, default, and parameterized constructor." public ItemType(String name, Double deposit, Double costPerDay). Override toString() and print the details.Input format :The first line of the input consists of the name.The second line of the input consists of the deposit.The third line of the input consists of the cost per day.Output format :The output prints the item details or the exception details.Refer to the sample input and output for format specifications.Sample test cases :Input 1 :Electronics1000100Output 1 :Electronics 1000.0 100.0Input 2 :Electronicsone thousandOutput 2 :java.lang.NumberFormatException: For input string: "one thousand"
