Question

Write a Program to create a SDA to store 25 numbers. Then display the following data:

1. The highest number and its index position.
2. The lowest single digit number. 
3. Percentage of two digits numbers.

Answer 1

import java.util.Scanner;


public class App {


	/**
	 * The start point of the program
	 * 
	 * @param args
	 * 
	 */
	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		int numbers[] = new int[25];
		for (int i = 0; i < 25; i++) {
			System.out.print("Enter the number " + (i + 1) + ": ");
			numbers[i] = keyBoard.nextInt();
		}
		int highestNumber = numbers[0];
		int highestNumberIndex = 0;
		int lowestSingleDigitNumber = Integer.MAX_VALUE;
		double totalTwoDigitsNumbers = 0;
		for (int i = 1; i < 25; i++) {
			if (numbers[i] > highestNumber) {
				highestNumber = numbers[i];
				highestNumberIndex = i;
			}
			if (numbers[i] < lowestSingleDigitNumber && numbers[i] >= 0 && numbers[i] < 10) {
				lowestSingleDigitNumber = numbers[i];
			}
			if (numbers[i] > 9 && numbers[i] < 100) {
				totalTwoDigitsNumbers++;
			}
		}
		double percentageTwoDigitsNumbers = (totalTwoDigitsNumbers / 25.0) * 100.0;
		System.out.println(
				"The highest number is: " + highestNumber + " and its index position is: " + highestNumberIndex);
		if (lowestSingleDigitNumber == Integer.MAX_VALUE) {
			System.out.println("There is not lowest single digit number in the array");
		} else {
			System.out.println("The lowest single digit number is: " + lowestSingleDigitNumber);
		}
		System.out.println("Percentage of two digits numbers is: " + percentageTwoDigitsNumbers);
		keyBoard.close();
