PROGRAMMING EXERCISES:
READING DATA FROM A TEXT FILE
1. Create a program that reads five (5) names and five (5) numbers from a data file
that you will need to create and name phoneNumbers.txt. The file should
contain a name on one line followed by the person’s phone number on the next
line. The program must then read and output each name and phone number to
a JTextArea when the user clicks OK.
Your program output should look something like this:

2. Create a program that reads from a comma-delimited data file called
highScores.txt which contains the names of five players and five scores.
Each line within the file should contain a name and a score (commadelimited). The program should be able to read and output each person’s
name and score and calculate the average score, highest score and lowest
score.
