My issue

i got the solution but it shows failed test case, what is the solution?
int arr = new int[100];
arr[0]= 8;
arr[1]=2;
arr[2]=4;
arr[3]=1;
arr[4]=4;
int size= 5;
int sum=0;
for (int i=0; i<size; i++){
sum+=arr[i];
}
System.out.print(sum + " ");
}
}

My code

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

class Codechef
{
	public static void main (String[] args) throws java.lang.Exception
	{
		int[] arr = new int[100];
		arr[0]= 8;
		arr[1]=2;
		arr[2]=4;
		arr[3]=1;
		arr[4]=4;
		int size= 5;
		int sum=0;
		for (int i=0; i<size; i++){
		    sum+=arr[i];
		}
        System.out.print(sum + " ");
	}
}
