int iEnd = i == grid.length - 1 ? 0 : 1;

英文:

I should probably know that but I'm not sure what this line of code is doing:

int iEnd=i==grid.length - 1 ? 0:1;

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
and you can read more about it here: https://docs.oracle.com/javase/tutorial/java/nutsandbolts/op2.html
