I keep messing this up; can show me how to do this, like a walkthrough?

Please turn in a complete Java program which reads a sequence of numbers from the file "numbers.txt" and prints out each number, one per line, followed by a space, followed by a number of asterisks equal to that number. For instance, if numbers.txt contains: 3 2 1 Your output should be: 3 *** 2 ** 1 * Name of program should be: BarChart.
