不同的for循环增量值(Different for-loop incremental value)

 我最近摆弄了一些for循环，并试图绕过它的一些逻辑部分。 虽然我在这一点上远远超出了循环的水平，但有时候我仍然倾向于有点奇怪。 
 
 但是，我发现for循环的增量值取决于你是在循环内部还是外部： 
 
int i;
for(i = 0; i < 10; i++) {
   System.out.println(i); // 0 ... 9
}

System.out.println(i); // 10
 
 现在，我担心有一天我会到达一个地方，我将不得不使用计数器，而不仅仅是将它与条件相匹配...... 
 
 现在我想我明白为什么会这样; 在条件失败并且循环死亡之后，我正在增加，但是真的应该发生吗？ 
 
 是否有任何数学/逻辑（或优雅）方式在循环终止后不能使其进入N + 1，我在这里缺少？ 

I recently fiddled around with some for loops, and tried to get my head around some of the logical part of it. While i'm far beyond the level of loops at this point, I still tend to get a bit weird when it comes to logic sometimes.
 
However, I found that the incremental value of a for loop is different depending on whether you are inside or outside the loop:
 
int i;
for(i = 0; i < 10; i++) {
   System.out.println(i); // 0 ... 9
}

System.out.println(i); // 10
 
Now, i'm afraid one day i'll come to a point where i'll have to use the counter for something more than just matching it against the condition...
 
Now I think I understand why this is happening; i is being incremented after the condition fails and the loop dies, but is that really supposed to happen?
 
Is there any mathematical/logical (or elegant) way to not make it go N+1 after loop termination, that i'm missing here?
