Write a Java class called PyramidVolume that reads from the user 2 integers represent area of the base (B) and the height of a pyramid (h). Then calculates and prints the volume of this pyramid (rounded to 1 decimal place) according to the following formula: volume = (1/3) h B Note: If the user enters any non-positive value (i.e. less than or equal to zero), an error message should be displayed and nothing should be calculated. Paragraph - B I && 4

In Java Write a program that lets the user guess whether the flip of a coin results in heads or tails. The program randomly generates an integer 0 or 1, which represents head or tail. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect.
Find the internal representation of the integer: 450 (in 32-bit memory location). Please, do not insert any blanks in your answer.
Question I need a java program for a Craps game When the program is run, it will prompt the player for the starting balance of their account (in dollars). At the start of each game, the player will be asked for their bet. The bet must be at least $1, but cannot exceed the balance of their account During the game, the outcome of each roll must be output to the display. When the outcome of the game is decided, the account balance must be updated accordingly based on the player’s bet. If the player wins, the amount of the bet is added to the account balance; if the player loses, the account balance is decreased by the bet amount. At the end of each game, the game outcome must be summarized (e.g., player wins or loses), along with the player’s updated account balance. The player will continue to play Craps games until one of the following conditions occur: They voluntarily elect to end the session. After each game, once all required information has been output, the player will be…

With your current Java knowledge, you have decided to write a program that will calculate a student's GPA for the current semester. The program should prompt the user to enter four values representing the number of A, B, C and Ds earned for the semester then calculate and display the GPA. When writing the program, consider the following: • The program should prompt the user to enter four INTEGER values representing the number of grades earned for each letter grade. • GPA is calculated by dividing the total points earned by the total number of credits attempted. • All of the courses taken for the semester are 4 credits. • To determine the calculations, A grades have a point value of 4, B grades a point value of 3, C grades a point value of 2 and D grades a point value of 1. • Total Number of Credits Attempted = Sum of Number of Courses multiplied by the number of credits for each course. • The total points earned is the sum of the credit hours multiplied by the point value for each…
in Java Tasks Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 3. The computer's choice is displayed. Tasks 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.) C. If one player chooses paper and the other player chooses rock, then paper wins. (Paper wraps…

Kinetic energy is the measure of the work that an object does by virtue of its motion. It is best illustrated by the formula: KE = 0.5 mv² Create a java class that will call a method that will compute for the kinetic energy. Sample output: Enter mass of an object: 54 Enter velocity of an object: 2.87 The kinetic energy of an object is: 222.40 joules Note: 1. The result should be in 2 decimal places. 2. Apply the exception handling method. 3. SCREENSHOTS NOT ALLOWED! 4. Save your file as KineticPT.java.
CODE IN C# NOT JAVA (reject if you can't do C# please): Write an application that runs 1,000,000 games of craps and answers the following questions (explain each step): How many games are won on the first roll, second roll, …, twentieth roll and after the twentieth roll? How many games are lost on the first roll, second roll, …, twentieth roll and after the twentieth roll? What are the chances of winning at craps? [Note: You should discover that craps is one of the fairest casino games. What do you suppose this means?] What is the average length of a game of craps?

The following problem shows up in a number of Java texts, including Savitch's textbook: The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate, or BMR. The calories needed for a woman to maintain her weight is: WBMR = 655 + (4.3 × weight in pounds) + (4.7 × height in inches) − (4.7× age in years) The calories needed for a man to maintain his weight is: MBMR = 66 + (6.3 × weight in pounds) + (12.9 × height in inches) − (6.8 × age in years) A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input his or her weight in pounds, height in inches, and age in years. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for both a woman and a man of the input weight, height, and age. NOTE: This is an application of a selection statement! Input Data: Use a named constant for the…
