Java program to find largest element of array

import java.util.*; public class Main { public static void main(String[] args) { Scanner sc=new Scanner(System.in); System.out.println("Enter +ve array size"); int n=sc.nextInt(); int arr[]=new int[n]; int largest1 = 0; //using for loop int largest2 = 0; //using for each loop System.out.println("Enter array elements"); for(int i=0;i<n;i++) { arr[i]=sc.nextInt(); } for(int i=0;i<n;i++) { if(arr[i]>largest1) { largest1=arr[i]; } } System.out.println("Using For loop Largest element is "+ largest1); for (int num: arr) { if(num>largest2) { largest2=num; } } System.out.println("Using For each loop Largest element is "+ largest2); } }
