THIS IS MEANT TO BE IN JAVA So far we've learned variables, branches, loops, and some array. The assignment is: Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); The output ends with a newline. This doesn't make sense to me.... Please show the end result and explain why you added what you added. This is what I have so far: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { } }

In JAVA ASSIGNMENT DESCRIPTION: A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("After 6 hours: %.2f mg\n", yourValue); Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg. THE CODE I HAVE SO FAR: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); double caffeineMg; // "double" supports floating-point like 75.5, versus int for integers like 75. caffeineMg = scnr.nextDouble(); System.out.printf("After…
Write a Java program that inputs three integer variables (called a, b, and c) that represent the length of the sides of a triangle. Your program should store the type of the triangle in an enumeration variable (called type), and display the value of the variable type. Here are the steps to follow: 1- Defines an enumeration to represent the different triangle types: EQUILATERAL, ISOSCELES, SCALENE, and ERROR. The type ERROR is added in case that the value of any triangle sides is less than or equal to zero. 2- Declare then input the three integer variables a, b, and c using a scanner object called keyboard. 3- Declare the enumeration variable type. 4- Determine the type of the rectangle (i.e. Assign a value to the variable type) 5- Print the value of the variable type. NOTE: If all sides are equal, the rectangle is EQUILATERAL. If only two sides are equal, the rectangle is ISOSCELES, otherwise the rectangle is SCALENE. Note that the type of the rectangle should be ERROR if the length…
THIS IS MEANT TO BE IN JAVA So far we've learned variables, branches, loops, and some array. The assignment is: Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. Ex: If the input is: n Nobody the output is: 0 n's n is different than N. Please show the end result and why you added what you added.

1. In the game of Monopoly, a pair of dice are rolled to move a player's piece around the board. If a double is rolled (the dice show the same number), the player receives another roll of the dice. If a double is rolled a second time, a third roll of the dice is received. If a double is rolled on the third occasion, the player forfeits their turn (and goes to Jail). Write a program which simulates two players having 50 turns each (a turn however many dice rolls a player has in a row before it's the other player's turn) and determines: a) the total number of spaces moved by each player; and b) how many times a player rolls a double which results in movement of a piece. Use the randi function. For fun, incorporate the rule that a player cannot leave Jail (cannot move) unless they either roll a double or three turns have passed without rolling a double.
Use java Only. Introduction: The equation of a straight line is written as y = mx + b where m is the slope of the line and b is the value of y when x = 0. If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance…
For the following problem, write a program (in as close to Java code - but doesn't need to be compilable/runnable code, ie no English explanation "vague" pseudocode and all helper methods must be defined) 248 A few years ago, 2048 was a popular game to download and play on the smartphone. You don't need to know anything about 2048, but here is a different game called 248. In 248, the game starts with a sequence of N integers where N is between 2 and 248 (inclusive) and each integer in the sequence is between 1 and 40 (inclusive). To play the game, the player must select two adjacent integers with equal values and replace them with a single integer of value one greater. For example, two adjacent 3's can be replaced with a 4. After repeatedly doing combination operations there will eventually be no more equal adjacent numbers in the sequence and the game is then done. The score at the end of a game is whatever number is largest in the final sequence. Write a program to find the largest…

Coronavirus (COVID-19) is causing a lot of panic the world over. Most people in developing countries are panicking because there are not proper test kids to determine whether one has the virus or not. You have been consulted to develop a program that could be used as a first step in determining the likelihood that one has it or not so that persons could then be referred to the testing center to be tested. Your task is to:a. Write a java program that request for1. A person’s age2. Temperature3. Dry cough4. Sneezing5. Running nose b. Your program should refer to the testing center when:1. Temperature >38oC and Sneezing, Running nose, Dry cough allrespond to yes 2. Or Temperature >38oC and any two from “a 3 – 5” above all respondto yes 3. Otherwise your program shouldn’t display go home
ISP-Java Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. For coding simplicity, output a space after every integer, including the last. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first.
3) Suppose an airline company has hired you to write a program for choosing the passengers who should leave an overbooked flight. That means the airline has booked too many passengers hoping some of them would not show up on time, but passengers are on board and the aircraft doesn't have enough seats available for all these passengers. Your program chooses the passenger who must leave the flight. Passengers will be ranked based on the fare they have paid for booking (a double number called fare), and their number of loyalty points (an integer number called points). Fare and points are equally important, that means, in order to decide the position of each passenger in the list, fare and points each have 50% importance. A Person with minimum priority (combination of fare and points) will leave the flight. You need to define a class called Passenger with these member variables: passenger's name • fare points. Passenger class must have 3 accessors, 3 mutators, a constructor with three…
Java: Receives a phrase and returns the converted phrase to Pig Latin. A word is translated into Pig Latin according to the following rules: a. If there are no vowels in the word, then add “ay” to the end of it. (a, e, i, o, and u are all the vowels considered). b. If the word begins with a vowel, then add “yay” to the end of it. c. Otherwise, take all the letters up to the first vowel and move those letters to the end then add “ay”. Sample Input: System.out.println(toPigLatin("I am fluent in Pig Latin")); System.out.println(toPigLatin(“Hey”)); Sample Output: Iyay amyay uentflay inyay igPay atinLay Heyay
