Please use Java to write a method only as described. You do not need a complete program or class.

**Task Title: Rarest Value Finder**

**Language/Type:** Java TreeMap Collections
**Related Links:** [TreeMap](https://docs.oracle.com/javase/8/docs/api/java/util/TreeMap.html) | [String](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html)

---

**Objective:**

Write a method named `rarest` that accepts a `TreeMap` from strings to strings as a parameter. The method should return the value that occurs least frequently in the map. If there is a tie, return the value that comes earlier in alphabetical order. If the map is empty, the method should throw an `IllegalArgumentException`.

**Example:**

Suppose a variable called `map` contains the following elements:

```java
{"Alyssa":"Harding", "Char":"Smith", "Dan":"Smith", "Jeff":"Jones", "Kasey":"Jones",
"Kim":"Smith", "Morgan":"Jones", "Ryan":"Smith", "Stef":"Harding"}
```

Calling `rarest(map)` would return `"Harding"` because that value occurs 2 times, fewer than any other.

**Note:** The method examines the values in the map, not the keys.

---

**Constraints:**

- You may create one additional data structure (stack, queue, set, map, etc.) as auxiliary storage. You can use as many simple variables as necessary.
- Do not modify the contents of the map passed to your method.
- Ensure your method signature prevents modification from any caller.
- Your solution should have a time complexity of no worse than O(N log N), where N is the number of pairs in the map.

Make sure each program has at least one method in addition to its driver method(main). Or use one driver main method and write method(s) for each of the program. It is a single program not two individual questions so please write both. Write a java program to compute each of the following, use a separate method for each. (i) Calculate the energy of a flight traveling at the speed of light, use e = mc2 take c as the speed (3*108), e = energy and m is mass of the flight. Prompt the user to enter the mass. (ii) Calculate the size of the gravitational force acting between you and your friend as you approach each other (center-to-center 1 meter apart) in the hall way. Use the formula below. Prompt the user to supply the values of M and m. ? = (?∗?∗m)/d2M = Mass of your friend m = Your mass d = center-to-center distance 1m G = 6.67 * 10 -11

Create a Java program that does the following: 1. Ask the user to enter a retail price 2. Ask the user to enter a discount percentage (you can decide the format - 20 or .20) 3. Code a new method, calcSalePrice that accepts the retail price and discount percentage as parameters, and returns the sale price using the formula: retail price - (retail price * discount percentage) 4. Create a variable that will hold the return value from the method. 5. Assign the calcSalePrice return value to the variable, and then print out the sale price from the main method.
Java Methods Discussion Please "write an entire method (method header and body) for each option below in which it makes sense to use a: 1. void method (other than main method) 2. value-returning method "Please give an actual code example with explanation for each and not just a definition of what these mean. By *explanation, I mean why did you select to have it have a "void" return vs. a "value" return? Relate this to what happens inside the method.
Directions: SHOW ALL YOUR WORK. REMEMBER THAT PROGRAM SEGMENTS ARE TO BE WRITTEN IN JAVA. Notes: • Assume that the classes listed in the Java Quick Reference have been imported where appropriate. • Unless otherwise noted in the question, assume that parameters in method calls are not null and that methods are called only when their preconditions are satisfied. • In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. Writing significant amounts of code that can be replaced by a call to one of these methods will not receive full credit. Consider a guessing game in which a player tries to guess a hidden word. The hidden word contains only capital letters and has a length known to the player. A guess contains only capital letters and has the same length as the hidden word. After a guess is made, the player is given a hint that is based on a comparison between the hidden word and the guess. Each position in the…
