Explanation / Answer

import java.util.Scanner;

public class CountArray {

   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       int num;
       // creating count array
       int []count = new int[51];
       System.out.print("First input: ");
       num = sc.nextInt();
       while(true){
           if(num == 0){// stop
               break;
           }
           if(num < 0 || num > 50){
               System.out.println(num+" is not a valid input.");
           }else{
               count[num]++; // incrementing count
           }
           //reading next input
           System.out.print("Next input: ");
           num = sc.nextInt();
       }
       sc.close();
       System.out.println();
       //printing count array
       System.out.println("Value       Count");
       for(int i=1; i<=50; i++){
           if(count[i] == 0)// ignore
               continue;
           System.out.println(i+":       "+count[i]);
       }
       System.out.println();
       System.out.println("Program completed.");
   }
}
