Java arithmetic works from left to right. The [] has a high precedence, rather like (), so the i++ in the [] is evaluated first, then the i++ after the = then the 3ed i++.

Remember that i++ increments the value of i, but the whole expression returns the old value of i.

Now you should be able to work it out for yourself.
 
It is sorta covered in the JavaRanch Style Guide.
