In Java Write a program that checks the properness of a given variable name. Morespecifically, your program should specify whether a user-entered variable nameis (1) illegal, (2) legal but uses poor style, or (3) good. There are differentopinions as to what constitutes a good style for a variable name. For thisprogram, check for good style using these rules:· Only use letters and digits.· Use a lowercase letter for the first character.You do not need to check for an uppercase letter for the first letter in the secondand third words, ...etc.Your program should repeatedly prompt the user for variable names until the userenters "q" or "Q." the program terminates when the user enters the "q" or "Q."

Your team was asked to program a self-driving car that reaches its destination with minimum travel time. Write an algorithm for this car to choose from two possible road trips. You will calculate the travel time of each trip based on the car's current speed and the distance to the target destination. Assume that both distances and car speed are given. The programming language I'm using is Java. So, it'll be appreciated if the solution was in Java Thanks
