Help me in solving PRACTICEPERF problem

My issue


My code

/* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;

/* Name of the class has to be "Main" only if the class is public. */
class Codechef
	public static void main (String[] args) throws java.lang.Exception
		// your code goes here
		int count = 0;
		Scanner scan = new Scanner(;
		int[] ar = new int[4];
		for(int i=0;i<ar.length;i++)
		    ar[i] = scan.nextInt();

The logic is simple just count the number of ar[i ] that are >=10 and then simply return its count.
