Exam 1z0-811 topic 1 question 29 discussion

All are true is the result that I got when compiled.

T T T T System.out.println(a++ > 10 || ++b <= 21); System.out.println(" " + a + " " + b); System.out.println(a > 10 && ++b <= 22); System.out.println(" " + a + " " + b); System.out.println(a <= 11 && b == 22); System.out.println(" " + a + " " + b); System.out.println(c++ == 31 && a++ == 11 || b++ == 22); System.out.println(" " + a); System.out.println(" " + a + " " + b + " " + c); The expression becomes true || true, which is true. Value of a after this line: 12 Value of b after this line: 23 Value of c after this line: 31

I tried to insert on the compiler and the result is : true true false true.

The answer is D, because both prefix (++a) and postfix (a++) operators kept its result. E.g: After the first println System.out.println(a++ > 10 || ++b <= 21); The value of a is 11, therefore by the time it reaches the fourth println, a++ would already be 12, not 11.

the answer is C

guys take care the output will be TRUE four times so the answer is C if you check it on the compiler you will get the same output i mention , because the || operator requires only one to be true.

Correct answer is D

C is the correct answer because the second part of D has post-increments so it's will stay 22 , the step after D B=23

The correct answer should be A. operand AND can only be true if both expression correct. OR can only be true if either one is correct.

Corret Answer should be D
