Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain fewer than 20 words.

Ex: If the input is: 

5 hey hi Mark hi mark

the output is: 

hey - 1
hi - 2
Mark - 1
hi - 2
mark - 1

Hint: Use two vectors, one vector for the strings and one vector for the frequencies.

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. 

Ex: If the input is: 

5 50 60 140 200 75 100

the output is:

50,60,75,

The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.

For coding simplicity, follow every output value by a comma, including the last one. 

Such functionality is common on sites like Amazon, where a user can filter results.

Imagine a class of TV with data members Name, brand, model and price. Give appropriate data types of data members. Write the following functions in this use case scenario.

·      Display function for all members and write this function outside of the class

·      Add three of constructors as discussed in class

·      Add destructor

·      Write setter and getter

·      Create object and call the function accordingly

·      All inputs should be user runtime inputs

Create a program named ConsoleAppException that divide 2 numbers and display the result. Ensure that your program implements the exception handling. Again, the program should have a constructor that initialize the result to zero. The calculation should happen in a method named Division() that takes two parameters (num1 and num2). The main method is only used to call the division() method . Use 25 for num1 and 0 for num2

Whole numbers are great, but I think we should also pay attention to decimal numbers, too.

So, how about we make a program that involves a lot of decimals?

Instructions:

1. Continuously ask for floating point values (decimal numbers) using the do…while() loop, sum them all up, and store the total into one variable.
2. The loop shall only terminate for the following reasons:
3. A negative decimal number is inputted (but still included in the total sum)
4. The total sum reaches 100.0 or more

Input

Multiple lines containing float number on each.

1.1
1.2
1.3
1.4
-1.0

Output

A line containing a float number with two decimal places.

4.00

Create a class named Apartment that holds an apartment number, number of bedrooms, number of baths, and rent amount. Create a constructor that accepts values for each data field. Also create a get method for each field. Write an application that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent that the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or an appropriate message if no such apartments are available. Save the files as Apartment.java and TestApartments.java
