Please help me solve this with java .... just the HangMan HangMan instruction class : • HangMan is a game in which a player tries to guess a word based on a given hint. For example, if the given hint is “movie”, then the player must guess a movie name. If the given hint is a “country”, then the player must guess a country name, and so on.• The game starts by showing a message on the screen that shows the hint and all letters in the word but obscured as dashes (-). Then, the game will allow the player to guess 5 letters. If the player gives a letter that actually exists in the word, then this letter will be revealed. Afterwards, the game will ask the player to give the answer. If the given answer is correct, then the game will show a message that the player has won 5 points. Otherwise, the game will show a message that the player has lost. Below is one possible game scenario, in which the word is “iron man”, and the hint is “movie”. Note that the text in green color is the…

A rational number is the quotient of two integers - the numerator and denominator. The denominator cannot be zero. Two rational numbers can be added, subtracted, multiplied and divided. Write a java classRational for a rational number with the following specs: • A constructor that gets two integers (make sure the denominator is not 0).• The numerator and denominator should be private.• Getters: public int getNumerator() and public int getDenominator()• Setters: public void setNumerator(int n) and public void setDenominator(int d)• Public methods public Rational add(Rational r1), public Rational subtract(Rationalr1), public Rational multiply(Rational r1) and public Rational divide(Rational r1).• Printer function: public void print(). The number should be printed in the format n/d (numerator, forward-slash, denominator).
A supermarket awards coupons depending on how much a customer spends on groceries. For example, if you spend $50, you will get a coupon worth eight percent of the amount. The following table shows the percent used to calculate the coupon awarded for different amounts spent. Write a JAVA program that calculates and prints the value of the coupons a person can receive based on groceries purchased. Money Spent Coupon Percentage Less than 10$ No coupon $10-$59 8% $60-$149 10% $150-$209 12% $210 or more 14% Here is a sample run: Please enter the cost of your groceries: 14 You win a discount coupon of $1.12. (8% of your purchase)

This needs to be done in Java! (Sales Commission Calculator) A large company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who sells $5,000 worth of merchandise in a week receives $200 plus 9% of $5,000, or a total of $650. You’ve been supplied with a list of the items sold by each salesperson. The values of these items are shown below. Develop a Java application that inputs one salesperson’s items sold for last week and calculates and displays that salesperson’s earnings. There’s no limit to the number of items that can be sold. Item Value 1 239.99 2 129.75 3 99.95 4 350.89 Example Output:   Enter number sold of product #1: 10Enter number sold of product #2: 20Enter number sold of product #3: 30Enter number sold of product #4: 40Earnings this week: $2182.61 NOTES: Do not create a separate class for this program.
