Java program to find the maximum and minimum value of an array

In this article we will learn to implement a Java program to find the maximum and minimum value of an array. A java program is provided below which reads array elements from the user and finds out the maximum, minimum elements in the array.

Program is as follows:

import java.util.Scanner;

public class Driver
{	
	public static void main(String[] args)
	{
		Scanner input = new Scanner(System.in);
		System.out.println("Enter the no. of elements: ");
		int n = input.nextInt();
		int a[] = new int[n];
		System.out.println("Enter " + n + " numbers:");
		for(int i = 0; i < n; i++)
			a[i] = input.nextInt();
		int max = a[0], min = a[0];
		for(int i = 1; i < n; i++)
		{
			if(max < a[i])
				max = a[i];
			if(min > a[i])
				min = a[i];
		}
		System.out.println("Max. number in the array is: " + max);
		System.out.println("Min. number in the array is: " + min);
		input.close();
	}
}

Input and output for the above program are as follows:

Enter the no. of elements: 
5
Enter 5 numbers:
1 6 8 -1 -2
Max. number in the array is: 8
Min. number in the array is: -2
