write a java code

1. Write a java program that prompt the user to enter his age. The program should display “You cannot ride a car” if age is less than 18, else it should display “Enjoy your ride!!” 2. Write a java program that compute salary by prompting a user to enter his/her salary and Years of service in an organization. (Hint Salary= Salary + bonus ) i. Assume that a bonus of 5% of salary is added to the salary of only those earning more than 20,000 and have served the company for 10 years. ii. Else a bonus of 2 % of salary is added. 3. Consider a bank that offers four different types of account (‘A’, ‘B’, ‘C’and ‘X’). The following table illustrates the annual rate of interest offered foreach type of account. Account Annual Rate of Interest (%) A 1.5 B 2 C 1.5 X 5 Design and implement a program that allows the user to enter an amount ofmoney and a type of bank account, before displaying the amount of money thatcan be earned in one year as interest on that money for the given type of bankaccount. You should use the switch statement when implementing this program. Hint: be careful to consider the case of the letters representing the bankaccounts. You might want to restrict this to, say, just upper case. Or you couldenhance your program by allowing the user to enter either lower case or uppercase letters. 4. a. Using a for loop, write a program that displays a “6 times” multiplicationtable; the output should look like this: 1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36 7 * 6 = 42 8 * 6 = 48 9 * 6 = 54 10 * 6 = 60 11 * 6 = 66 12 * 6 = 72 b. Modify the program further by making use of a while loop to carry out some input validation that ensures that the user enters a number that is never less than 2. If a number less than 2 is entered an error message should be displayed and the user is asked to enter another number. c. Finally, make use of a do…while loop so that the user is asked to enter ‘y’ or ‘n’ to indicate if they wish to run the program again. Ideally the program should run again if the user enters ‘y’ or ‘Y’. 5. Design and implement a program that converts a sum of money to a differentcurrency. The amount of money to be converted, and the exchange rate, areentered by the user. The program should have separate methods for: • Obtaining the sum of money from the user; • Obtaining the exchange rate from the user; • Making the conversion; • Displaying the result.
