Java数组索引超出范围？

Question

有人可以帮我解决下面发布的错误吗？该程序运行,但在调用显示捐赠时,我收到关于我的主要的错误.我怎么能解决这个问题呢？是否与语法错误有关？这是我第一次使用数组,所以我欢迎有关良好习惯的反馈.谢谢!

Answer 1

static double[] cashDonations = new double[6];

这是一个有6个空格的数组,正确.然而:

maxCash = cashDonations[0];
totalCash = cashDonations[1] + cashDonations[2] + cashDonations[3] + cashDonations[4] + cashDonations[5] + cashDonations[6];

在这里,您正在访问7个空格.0,1,2,3,4,5和6.
