223. Rectangle Area

蠢错误翻得够够的。

注意的地方就是，有可能并没有overlap

下次一定要看清题目。

注意变量的scope.

注意返回

 1     public int computeArea(int A, int B, int C, int D, int E, int F, int G, int H) {
 2         int overlap = 0;
 3         if((E < C && F < D) && (G > A && H > B)) {
 4             int I = Math.max(A, E);
 5             int J = Math.max(B,F);
 6             int K = Math.min(C,G);
 7             int L = Math.min(D,H);
 8             overlap = (K - I) * (L - J);
 9         }
10         System.out.println(overlap);
11         return (C - A) * (D - B) + (G - E) * (H - F) - overlap;
