答案1
得分: 0
它将在i等于grind.length - 1时将iEnd设置为0，否则将iEnd设置为1。
这个操作符被称为“三元运算符”，是“条件运算符”的简写形式，你可以在这里阅读更多关于它的信息：https://docs.oracle.com/javase/tutorial/java/nutsandbolts/op2.html https://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html
英文:
it will set iEnd to 0 if i equals grind.length -1 otherwise it will set iEnd to 1
the operator is called Ternary Operator and is a short hand for a Conditional Operator
