Description:
Prompts the user to enter several numbers of choice to compute average, minimum, maximum, sum, first number entered, last number entered, count of number entered. User enters zero to complete data

Code:

import java.util.*;

     * @param args the command line arguments
     */

        int last_num = 0; 
        //holds the max and min numbers.
        int maxNum = Integer.MIN_VALUE; // Maximum number.    
        int minNum = Integer.MAX_VALUE; // Minimum number.

        // compute the average.
        int count = 0;              // Number of input values.
        int totalNum = 0;              // Total of all numbers. 
        // Loop until 0 is entered.
        System.out.println("Please enter any numbers(The program exits if the input is 0): "); 

        while (input.hasNextInt()) {

            if (number == 0) { 
                break; 
            }

            // Compare the value to max and min.
            if (number > maxNum) {
                maxNum = number;

        	   last_num = number;
           }
            count++;                 // Count the number entered.
            totalNum += number;      // Keep a running total.
        }


            double average = totalNum / count;
            System.out.println("The first number entered = " + first_num); 
            System.out.println("The last number entered = " + last_num);
            System.out.println("Number of values = " + count);
            System.out.println("Maximum = "  + maxNum);
            System.out.println("Minimum = "  + minNum);
            System.out.println("Average = "  + average); 
            System.out.println("Sum = " + totalNum);
