maximum and minimum element in the array

In this article, we are going to find maximum and minimum element in the given array using java code.

Example:-

if n=4(size of an array)

arr={48,58,5,2}, then the output will be 58 is the maximum element and 2 is the minimum element.

steps:-

• Take array input from user using scanner.
• Take a variable min and initialize it with maximum possible value.
• Take another variable max and initialize it with minimum possible value.
• Run a loop to iterate elements of array.
• inside the array check if min is greater then array element then update min with array element else update max with array element.
• end of loop.
• variable max and min will be hold the maximum and minimum element in array.

Java code to find maximum and minimum element in an array:-

package gangforcode;

import java.util.Scanner;

public class MinArray {

	public static void maxmin(int[] arr) {
			int min = Integer.MAX_VALUE;
			int max= Integer.MIN_VALUE;
			for(int i=0;i<arr.length;i++) {
				if(min>arr[i]) {
					min=arr[i];
					
				}else {
					max=arr[i];
				}
			}
			System.out.println("minimum element in the array is "+min);
			System.out.println("maximum element in the array is "+max);
		}
	public static void main(String[] args) {
		Scanner sc= new Scanner(System.in);
		System.out.println("Enter the size of array");
		int n=sc.nextInt();
		int[]arr=new int[n];
		for(int i=0;i<n;i++) {
			arr[i]=sc.nextInt();
		}
		maxmin(arr);
	}}

Output:-

You can use the same logic to find minimum and maximum element in array using other programing languages like C, C++, Python etc.
