[NowCoder](https://www.nowcoder.com/practice/459bd355da1549fa8a49e350bf3df484?tpId=13&tqId=11183&tPage=1&rp=1&ru=/ta/coding-interviews&qru=/ta/coding-interviews/question-ranking&from=cyc_github)
## 题目描述
{6, -3, -2, 7, -15, 1, 2, 2}连续子数组的最大和为 8从第 0 个开始到第 3 个为止
## 解题思路
```java
public int FindGreatestSumOfSubArray(int[] nums) {
if (nums == null || nums.length == 0)
return 0;
int greatestSum = Integer.MIN_VALUE;
int sum = 0;
for (int val : nums) {
sum = sum <= 0 ? val : sum + val;
greatestSum = Math.max(greatestSum, sum);
}
return greatestSum;
}
```
