Answer: A, D

Explanation:

B is partially true because the expression is evaluated even at the beginning of the loop.
C i wrong because expr3 is optional.

D is correct because we have other forms of writing for loops:

int array[] = {1, 2, 3};
for(int i : array){
}

Completed 1Z0-803 exam few days ago! Scored 90% (the passing score is 63% now)!!

Had 70 questions in my actual 1Z0-803 test.

1. Most of the questions are on Giving Code … tell the result, insert CODE, choose the best option …etc.

2. Only few questions on Java: advantages of the Java exception mechanism, benefits of using ArrayList over array, valid types for switch, Java Exception classes, two-dimensional array, improve the encapsulation of a class, java class declaration … and so on.

Used valid 1Z0-803 dumps from PassLeader (http://www.passleader.com/1z0-803.html) (272q VCE and PDF), almost all questions were same as my 1Z0-803 exam, valid enough for passing until now!
