1. Create a program that reads in numbers from a file and determines if they are in between two other numbers. For example, it might print a message if the number is between 1 and 5.
2. Repeat the previous exercise but read the numbers from a console, and quit the program when the user enters a negative number.
3. Create a static method that takes a number as an argument and returns an array of numbers. As an example, the method might take the number 5 and return an array of [5,10,15] (1, 2, and 3 times the input).
4. Create a program that stores strings in an ArrayList and then prints them to the console.
