1.题目描述：

给定数组nums,目标值target，在该数组中找出和为目标值的那两个整数，并返回数组的下标

2.代码实现：

public class Test {

public static void main(String[] args) {

int[] arr = {23,34,67,77};

int ret[] = twoSum(arr, 100);

System.out.println(Arrays.toString(ret));

}

public static int[] twoSum(int[] nums,int target){

int flag[] = new int[2];

for(int i = 0;i < nums.length;i++){

for(int j = i + 1;j < nums.length;j++){

if(nums[i] + nums[j] == target){

flag[0] = i;

flag[1] = j;

return flag;

}

}

}

return null;

}

}

simple.

}

catch (Exception e) {

}

return simples;

}

Input Error: java.lang.ArrayIndexOutOfBoundsException:1

能不能帮我解决下问题？
