int?i=score.length;i>score.length-3;i-- ?錯了,score.length應(yīng)該是7,當(dāng)i=7的時候,scores[7]就越界了,因為score下標(biāo)最大只到6,

數(shù)組下標(biāo)越界
2016-03-28
scores.length是7 ，但是數(shù)組下標(biāo)最大是6 所以應(yīng)該scores.length-1 ,代碼里還有一些空格的問題

越界了i=score.length 但是 0<=i<score.length
2016-03-23
角標(biāo)錯了 ? 一樓說的對

scores[i]里的i值是從零開始，int?i=score.length改為int?i=score.length-1，希望可以幫到你
