我所说的for循环的形式是for（int i=0；i这样写

ifor
循环的顺序是这样的：

Perform the initial expression (e.g. assign initial values)
BEGINNING OF 1ST LOOP ITERATION:
Check if the condition is true, and end the loop if it isn't
Do the body of the loop
Increment
BEGINNING OF 2ND LOOP ITERATION:
Check if the condition is true, and end the loop if it isn't
Do the body of the loop
Increment
BEGINNING OF 3RD LOOP ITERATION:
Check if the condition is true, and end the loop if it isn't
Do the body of the loop
Increment
...

依此类推。正如您所看到的，增量是在每次检查之前完成的，而不是像您所想的那样在检查之后完成的。
循环中的语句首先运行，然后递增“i”的值。这就是
i++
函数的工作方式，第一个循环的i=0，依此类推。因此，在第五次迭代中，i将等于4

当我在第五次执行语句后变为5时，它就不再满足条件
i你没有得到5的原因是因为逻辑运算符，条件是
iokay我非常理解这一点，我只是在讨论这个循环中的执行顺序…首先应该运行什么..检查还是增量状态
  for( int i = 0; i<=5; i++) {
    System.out.println(i);
  }   

 0
 1
 2
 3
 4
 5   

Perform the initial expression (e.g. assign initial values)
BEGINNING OF 1ST LOOP ITERATION:
Check if the condition is true, and end the loop if it isn't
Do the body of the loop
Increment
BEGINNING OF 2ND LOOP ITERATION:
Check if the condition is true, and end the loop if it isn't
Do the body of the loop
Increment
BEGINNING OF 3RD LOOP ITERATION:
Check if the condition is true, and end the loop if it isn't
Do the body of the loop
Increment
...

i = 0;
is i < 5? Yes.
[..] i = 5; is i < 5? No. 5 < 5 is false.

for (int i = 0; i <= 5; i++)
{ System.out.println(i); }
