Question

need java code for this question

Question 2 (15 marks) (a) Does the following class successfully compile? Explain your answer. public class MyClass public static void main(String arge) if(Integer.parseInt(args[0]) < 0) throw new RuntimeException(); C { 1 } If the class does compile, describe what will happen when we run it with command: java MyClass -10 (5 marks) (b) Write a complete definition of the method with the heading given below: public static double calculate insurance Premium double carValue, int driverige) throws Exception The method calculates the insurance premium for a car. It takes two parameters . carValue, which must be at least 10,000 dollars) • driverage, which must be between 18 and 90, inclusive The insurance premium is 5% of the value of the car if the driver is 21 years old or older. Otherwise, the premium is increased by 10% of the value of the car. The method is required to throw a checked exception if any of the parameters is outside the valid range (10 marks)

Answer 1

a) The class will be compiled successfully, as there are no syntax errors.

When we pass -10 as an argument, if condition will be true and the program will throw Runtime Exception null as shown in below image.

b)

Program is as follows: Try with different values of carValue and driverAge.

CODE:

import java.util.*;
public class MyClass
{
public static double calculateInsurancePremium(double carValue, int driverAge) throws Exception
{
if(carValue < 1000)
throw new InputMismatchException("carValue must be atleast 1000");
  
if(driverAge < 18 || driverAge > 90)
throw new InputMismatchException("Age does not lie in range");
  
double premium;
if(driverAge >= 21)
premium = 0.05 * carValue;
else
premium = 0.10 * carValue;
  
return premium;
}
public static void main(String [] args) throws Exception
{
double cv = 950;
int da = 25;
System.out.println(calculateInsurancePremium(cv, da));
}
}

OUTPUT:
