Your program will read in a list of high and low integer temperatures and city names from System.in using the Scanner class, then sort the information three different ways: by high temperature, low temperature, and by city name. It is a requirement of the assignment that an ArrayList is used to store the data internally, and the sort method that ArrayList implements for the List interface is used to do the sorting.

Here is some sample input/output. The program would first print out a prompt:

Enter high/low temperatures and city:

The user might then type or paste the following into the terminal or Netbeans' output window:

60 37 Dallas, TX 61 42 Kansas City, KS 75 57 Cleveland, OH 81 70 Fort Lauderdale, FL 79 55 Seattle, WA .

Notice that the input ends with a line starting with a period; as in Programming Project 1, the last line could start with any non-digit character. There is no limit on the number of lines of input the program might receive; since your program is using an ArrayList to store the temperature information for each city, it isn't necessary to know in advance how many lines there could be.

Then the program would produce the following output for the above input:

***List in original order*** Dallas, TX 37 60 Kansas City, KS 42 61 Cleveland, OH 57 75 Fort Lauderdale, FL 70 81 Seattle, WA 55 79 ***List sorted by low temperature*** Dallas, TX 37 60 Kansas City, KS 42 61 Seattle, WA 55 79 Cleveland, OH 57 75 Fort Lauderdale, FL 70 81 ***List sorted by high temperature*** Dallas, TX 37 60 Kansas City, KS 42 61 Cleveland, OH 57 75 Seattle, WA 55 79 Fort Lauderdale, FL 70 81 ***List sorted by city name*** Cleveland, OH 57 75 Dallas, TX 37 60 Fort Lauderdale, FL 70 81 Kansas City, KS 42 61 Seattle, WA 55 79

Notice that the city names come first on output but last on input, and that the temperatures are all lined up in a column. This will make it easier for your program to read the data, but it will be printed in a manner that is easier for a human to read
