Second highest number in an array

public class SecondHighest {
	
	public static int secondhighest(int[] arr){
		if (arr == null){
			return -1;
		}
		if (arr.length ==1){
			return -1;
		}
		int max = arr[0] > arr[1] ? arr[0] : arr[1];
		int max2 = arr[0]  max){
				max2 = max;
				max = arr[i];
			}
			else if (arr[i] > max2){
				max2 = arr[i];
			}
		}
		return max2;
	}
	
	public static void main (String[] args){
		int[] arr = {1,-2,4,7,-9,45,34,-92};
		System.out.println(secondhighest(arr));
	}
}
