Question

Write a Java program to find the maximum and minimum value of a 1-d array.

Answer 1

import java.util.*;


class App {


	public static int getMaxValue(int[] numbers) {
		int maxValue = numbers[0];
		for (int i = 1; i < numbers.length; i++) {
			if (numbers[i] > maxValue) {
				maxValue = numbers[i];
			}
		}
		return maxValue;
	}


	public static int getMinValue(int[] numbers) {
		int minValue = numbers[0];
		for (int i = 1; i < numbers.length; i++) {
			if (numbers[i] < minValue) {
				minValue = numbers[i];
			}
		}
		return minValue;
	}


	public static void main(String[] args) {
		Scanner keyboard = new Scanner(System.in);
		System.out.print("Enter size of array: ");
		int n = keyboard.nextInt();
		int[] numbers = new int[n];


		for (int i = 0; i < n; i++) {
			System.out.print("Enter number " + (i + 1) + ": ");
			numbers[i] = keyboard.nextInt();
		}


		System.out.println("The minimum value of a 1-d array: " + getMinValue(numbers));
		System.out.println("The maximum value of a 1-d array: " + getMaxValue(numbers));


		keyboard.close();
	}
