连续子数组最大和

public class Main {
    public static void main(String[] args) {

        int[] arr = {6,-3,-2,7,-15,1,2,2};
        int sum = arr[0];
        int tempSum = arr[0];
        for (int i = 1; i < arr.length;i++) {
            tempSum = tempSum < 0 ? arr[i] :arr[i] + tempSum;
            sum = tempSum > sum ? tempSum:sum;
        }
        System.out.println(sum);
    }
