any help with this mainly part B part A has already been finished

code for Part A:

CSCI 140/L. Java Project: Menu-Driven System Part A Write a menu-driven program that will give the user the three choices: 1) Wage calculator, 2) Tip Calculator, and 3) Exit. Class Name: PartA Password Access: For the user to gain access to the menu, they must enter a pin number (use pin 99 for this first program). You will prompt the user for the pin number. If the pin is correct, then display the menu. If the pin is incorrect, end the program with a message Thank you for using our menu system." 99 Wage Calculator: For the wage calculator, prompt for the name and hourly pay rate of an employee. Here the hourly pay rate is a floating-point number, such as $9.25. Then ask how many hours the employee worked in the past week. Be sure to accept fractional hours. Compute the pay. Any overtime work (over 40 hours per week) is paid at 150 percent of the regular wag (1.5 the hourly pay rate). Print the employee's name, regular hours worked, regular hours pay, overtime hours worked (do not show overtime hours, if there are none), overtime hours pay (do not show overtime pay if there is none), and total pay. [Do not prompt for overtime hours]) Tip Calculator: For the tip calculator, the tip is calculated based on the diner's satisfaction level. Ask for the diner's satisfaction level using these ratings: 1-Totally satisfied, 2-Satisfied 3-Dissatisfied. If the diner's choice is 1, calculate a 20 percent tip. If the diner's choice is 2, calculate a 15 percent tip. If the diner's choice is 3, calculate a 10 percent tip. Print the satisfaction level and tip in dollars and cents. [Format: "Your tip is $4.00 (Totally satisfied) Exit: The exit choice will display a statement that the program will end and thank the user for ing the program. [They must choose to exit the menu, not default out-it is a menu option] ur program should be complete and with correct convention (ie. Variable naming and declaration) and commenting (correct header with well-formed pseudocode). The obtain 50 o 100 points, your program must compile and run, You will obtain 30 points if your program runs correctly. You will obtain 20 points for all other convention and commenting (this includes file and class naming convention). All output should be properly formatted and user friendly
