Histogram That Allows To Visually Inspect Frequency Distribution Of A Set Of Values

Design and implement an application 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 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.

No input prompt

Terminate input by typing CTRL/Z (two keys typed at the same time) on a separate input line (use CTRL/D on Linux/UNIX systems)

Use hasNextInt() to terminate your input

Format as below (slightly different from the text example)

Z:dbraffittWeek10> javac Histogram.java

Z:dbraffittWeek10> java Histogram

10 10 10 10 10 20 20 20 20 20 20

20 25 35 45 55 65 75 85 95

ctrl/z

1 - 10 | *****

11 - 20 | *******

21 - 30 | *

31 - 40 | *

41 - 50 | *

51 - 60 | *

61 - 70 | *

71 - 80 | *

81 - 90 | *

91 - 100 | *

What I can not figure out is how to use hasNextInt() to terminate the loop. How to not have an input prompt. How to use ctrl z to terminate the input. Or to make it where it doesn't involve range values like -1.

Java Code:

import java.util.Scanner;
public class Histogram
{
public static void main (String[] args)
{
Scanner scan = new Scanner (System.in);
int [] nums = new int[101];
