题解：

class Solution {public int computeArea(int ax1, int ay1, int ax2, int ay2, int bx1, int by1, int bx2, int by2) {int area1 = (ax2 - ax1) * (ay2 - ay1), area2 = (bx2 - bx1) * (by2 - by1);int overlapWidth = Math.min(ax2, bx2) - Math.max(ax1, bx1), overlapHeight = Math.min(ay2, by2) - Math.max(ay1, by1);int overlapArea = Math.max(overlapWidth, 0) * Math.max(overlapHeight, 0);return area1 + area2 - overlapArea;}
}
