Question

i really need help with this java code, when i try to run it, an erros comes up

PP 8.3 Write a program that creates a histogram that allows
you to visually inspect the frequency distribution of a set of
values. The program should read in an arbitrary number of
integers from a text input file that are in the range 1 to 100
inclusive; then produce a chart similar to the one below that
indicates how many input values fell in the range 1 to 10, 11 to
20, and so on. Print one asterisk for each value entered.
