for循环的while部分是执行每次传递还是只执行一次java？

Question

例如,这会不变或每次通过都会改变？

for(int i = 0; i < InputStream.readInt(); i++)

Answer 1

 for(int i = 0;                  // executed once
     i < InputStream.readInt();  // executed before each loop iteration
     i++                         // executed after each loop iteration
    ) {
    ....
 }
