public class Solution
{
    public static int[] rowWeights (final int[] weights)
    {
        int result1 = 0;
        int result2 = 0;
        int len = weights.length;
        if(len==0){
          return new int[]{0, 0}; // Do your magic!
        }
        for(int i=0;i<len;i++){
          if(i%2==0){
            result1+=weights[i];
          }else{
            result2+=weights[i];
          }
        }
        return new int[]{result1,result2};
        
    }
}

大神的Solution

public class Solution {
  public static int[] rowWeights (final int[] weights) {
    int totals[] = new int[2], idx = 0;
    for (int w : weights) totals[(idx++)%2] += w;
    return totals;
  }
