Can anyone explain this java statement and the value of x after evaluating::- where int x=4

Question

x+=(x++)+(++x)+x

Answer 1

x = x + x++ + ++x +x
=4 + 4 + 5 + 4.
=17.

Is it correct?

Answer 2

Ok I got it.

x = x + x++ + ++x +x
=4
+ 4(now x=5)
+ 6 (x=6)
+ 6
=20.

because

IN PREFIX ++x FIRST x IS INCREMENTED AND THAN EVALUATION TAKE PLACE.

IN POSTFIX x++ FIRST EVALUATION IS DONE AND THAN ITS VALUE IS INCREMENTED.

Hope this helps ☺️☺️.
