Exercise 2: Write a program to simulate tossing a "fair" coin. . Allow the user to enter the number of tosses. . Print the number of tosses that yielded heads and the number of tosses that yielded tails. What should be the percentage distribution of heads and tails?

Write a program that asks the user to enter an amount of money in the format of dollars and remaining cents. The program should calculate and print the minimum number of coins (quarters, dimes, nickels and pennies) that are equivalent to the given amount.Hint: In order to find the minimum number of coins, first find the maximum number of quarters that fit in the given amount of money, then find the maximum number of dimes that fit in the remaining amount, and so on. Write a program that prompts for weight in pounds and height in inches, converts the values to metric, and then calculates the BMI.Note: 1 pound is 0.453592 kilograms and 1 inch is 0.0254 meters.

Write a program that asks the user how many credit units they have taken. If they have taken 23 or less, print that the student is a freshman. If they have taken between 24 and 53, print that they are a sophomore. The range for juniors is 54 to 83, and for seniors it is 84 and over.

Write a program that reads the result of 10 games played by a team and find the percentage of games won by the team. Output the percentage games won. Write an IPO Chart that reads the result of 10 games played by a team and find the percentage of games won by the team. Output the percentage games won.

This program inputs the names of 5 students and the (integer) grades they earned in 3 tests. It then outputs the average grade for each student. It also outputs the highest grade earned in each test and the average of all grades in each test. Your output should look like this: Mary's average grade was 78.8% Harry's average grade was 67.7% etc... : : In test 1 the highest grade was 93% and the average was 89.2% In test 2........etc Your main method should be modular. Write a method that inputs the 5 names into an array (one dimensional), and returns this array to the main Write a method that inputs the 15 (integer) test grades into a (two-dimensional) array, and returns this array to the main Write a method that calculates the students averages and stores them in an array, and returns this array to the main Write a method that calculates the average grade for each test and stores them in an array, and returns this array to the main Write a method that determines the highest grade...

QUESTION 7. Write a program that reads multiple integers from the user and finds the largest value. The program should ignore negative values and print a message indicating so. The sentinel is -1. If no valid input is entered, the program should print a message indicating so, like the second sample below. Use a flag variable that indicates whether valid input has been entered so far or not. Enter integer: 4 Enter integer: -5>>> Invalid input! Enter integer: 20 Enter integer: 12 Enter integer: 7 Enter integer: -1 The largest value is: 20 Enter integer: -5>>> Invalid input! Enter integer: -20>>> Invalid input! Enter integer: -1 No valid input was entered!

a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player's choice of either High or Low is compared to random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered "low". A number between 8 and 13 inclusive is "high". The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to: High Low Gane RULES 1 through 6_are lou Nunbers 8 through 13 are high Number ? is neither high or low You have 1000 points. Enter points to risk: 500 Predict (1=High, 0=Low): 0 Nunber is 4 You win. Play again? y You have 2808 points. b) Modify the application to...

A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated. (Submit for 2 points). (1) Output the user's input. Enter integer: 4 You entered: 4 (2) Extend to output the input squared and cubed. Hint: Compute squared as userNum * userNum. (Submit for 2 points, so 4 points total). Enter integer: 4 You entered: 4 4 squared is 16 And 4 cub is 64!! (3) Extend to get a second user input into userNum2. Output sum and product. (Submit for 1 point, so 5 points total). Enter integer: 4 You entered: 4 4 squared is 16 And 4 cubed is 64 !! Enter another integer: 5 4 + 5 is 9 4 * 5 is 20 283902.1980792.goazgy7 LAB 1.16.1: Basic output with variables (Java) 0/5 АCTIVITY OutputWithVars.java Load default template. 1 import java.util.Scanner; 2 3 public class OutputwithVars { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int userNum = 0; 4 System.out.println("Enter integer: "); userNum = scnr.nextInt(); 10 11...

3. Having a secure password is a very important practice, when much of our information is stored online. Write a program that validates a new password, following these rules: The password must be at least 8 characters long. The password must have at least one uppercase and one lowercase letter. The password must have at least one digit. Write a program that asks for a password, then asks again to confirm it. If the passwords don't match or the rules are not fulfilled, prompt again. Your program should include a function that checks whether a password is valid.
