Question

Write a program that reads an arbitrary number of integer that are in the range 0 - 50 inclusive and counts how many occurrences of each are entered. Indicate the end of the input by a value outside of the range. After all input has been processed, print all of the values (with the number of occurences) that were entered one or more times.

Answer:

Check the explanation

Explanation:

import java.util.Scanner;

public class Count

{

   public static void main(String[] args)

   {

       // creating array of store to store count of

       //every integer entered

       int[] store = new int[51];

       System.out.println("Enter any integers between"+

       " 0 and 50, and if you are done then enter any"+

       " integer out of the range");

       System.out.println("Enter Integer: ");

       //taking input of first integer

       Scanner scan = new Scanner(System.in);

       int integer = scan.nextInt();

       //looping for integers entered in range

       //to count its occurance

       while(integer >= 0 && integer <= 51)

       {

           //adding count to 'store' array of that

           //particular array of value entered

           store[integer] = store[integer] + 1;

           System.out.println("Enter Integer: ");

           integer = scan.nextInt();

       }

       //printing number of times each integer is entered

       System.out.println("printing number of times"+

           " each integer is entered");

       for (int i=0; i < 51; i++)

       {  

           if (store[i] > 0)

               System.out.println(i + ": " + store[i]);

       }

   }

}
