Question
Java.
Examine the following code:
What is the scope of the variable number? (Type your answer as two line numbers with a comma between. For example if a variable's scope would go from lines 5 to 10, you would type 5, 10.)

- For the 8 Java statements below, identify each of the following statements as legal or illegal, and whether legal or not, state whether it represents a "narrowing" or "widening" conversion, or neither. Don't forget to identify the last statement at the very bottom, Member m = new BoardMember();, as legal or illegal and widening or narrowing conversion.arrow_forwardUse java.arrow_forwardIn 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."

- basic java please Write a method called findTip that finds the value of a meal as a double after adding the tip to the cost. Then return this value to the calling function. For example findTip(120.10, 5) would 126.105 because that is a 5% tip. While findTip(48.0, 15) would return 55.2 because that is a 15% tip. Note that the bill is a double while the tip is an int. Don’t worry about rounding to two decimal places, just return the full value as a double.arrow_forwardJAVA METHOD OVERLOADINGarrow_forwardInstructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 milesarrow_forward
- Please use java only. In this assignment, you will implement a simple game in a class called SimpleGame. This game has 2 options for the user playing. Based on user input, the user can choose to either convert time, from seconds to hours, minutes, and seconds, or calculate the sum of all digits in an integer. At the beginning of the game, the user will be prompted to input either 1 or 2, to indicate which option of the game they want to play. 1 will indicate converting time, and 2 will indicate calculating the sum of digits in an integer. For converting time, the user will be prompted to input a number of seconds (as an int) and the program will call a method that will convert the seconds to time, in the format hours:minutes:seconds, and print the result. For example, if the user enters 6734, the program will print the time, 1:52:14. As another example, if the user enters 10,000, the program should print 2:46:39. For calculating the sum of digits in an integer, the user will be…arrow_forwardQuestion: Your task is to find the number of ways that you can put those brackets in such a way that they will be always balanced after taking the n pair of brackets from the user in Java Language.arrow_forwardPlease help me write a tic tac toe game using java.

- Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…arrow_forwardPlease help with the following in JAVAarrow_forwardFor the code in java below it shows a deck of 52 cards and asks the name of the two players and makes both players draw five cards from the deck. What I want to be added onto the code is the possibility for Player A too chose whatever card they want from his/her 5 cards and Player B has to chose two cards from his/her 5 cards that equal in value of Player A's card. I also want the cards that have been used to be replaced by different cards in the deck of 52 cards and that game to go on until the deck runs out of cards.
