2) A common IT task is to take a data file and process it so that it can be uploaded to a database. You are given a file in the following format:

Fred:1211 My Street:Houston:Texas

Ethel:1212 Another Street:Snook:Texas

... Create a class called FileConverter. In the class, create an instance method called convertFile() that reads in the datafile and writes it to a new file in the following format:

Fred|1211 My Street|Houston,Texas

Ethel|1212 Another Street|Snook,Texas

… Notice that in the input file, the city and state are two separate entries while in the output, they are combined using a comma.

The function convertFile does not require any parameters. You must call convertFile from the main function. The input file should be called “input_data.txt”. The output should be called “_hm1_output.txt”, where is your username
