public class Array_Max {

public static void main(String[] args) {

Scanner scn=new Scanner(System.in);

int n,max,location=1;

int a[]=new int[100];

System.out.println("Enter the number of integer in array =");

n=scn.nextInt();

System.out.println("Input "+n+" integer");

for(int i=1;i<=n;i++){

a[i]=scn.nextInt();

}

max=a[1];

for(int i=1;i<=n;i++)

if(a[i]>max)

{

max=a[i];

location=i;

}

System.out.println("Maximum is "+max+" at position "+location);

}

}

Output : 

 Enter the number of integer in array =
5
Input 5 integer
47
15
84
35
46
Maximum is 84 at position 3
