Question

Write a program that reads the integers between 1 and 100 and counts the occurrences of each. Assume the input ends with 0. Here is a sample run of the program:

Enter the integers between 1 and 100: 2 5 6 5 4 3 23 43 2 0
2 occurs 2 times
3 occurs 1 time
4 occurs 1 time
5 occurs 2 times
6 occurs 1 time
23 occurs 1 time
43 occurs 1 time

Note that if a number occurs more than one time, the plural word "times" is used in the output.

You must get (and verify) user input in its own method.
You must print the program output in its own method.
Other methods (including main!) may need to be created.

Answer 1

//CountOccurrenceOfNumbers.java
import java.util.Scanner;
public class CountOccurrenceOfNumbers {
    public static void main(String[] args) {
        System.out.print("Enter the numbers between 1 and 100: ");
        Scanner scan = new Scanner(System.in);
        int counts[] = new int[101];
        for(int i = 0;i1)
                System.out.println(i+" occurs "+counts[i]+" times");
            else if(counts[i]==1)
                System.out.println(i+" occurs "+counts[i]+" time");
        }
    }
}
