Question 42 · 200 in bank
Which is true about the switch statement?
Show answer
Answer: B
Question 43 · 200 in bank
Given the code fragment:
What is the result?
Show answer
Answer: D
Explanation
The answer is the letter D, you don't have to go far, both the initial value of the variable "i" and "j" receive the length -1 and the matrix is 2x2. As java indexes from 0 and length is 2, the first number to be printed is 4 which is in position [1][1] of the array and only the letter D has 4 as the first. Don't even waste time doing the rest, in the OCA test they put distractors just for you to spend more time on the question, and having additional time is like gold in this exam.

Question 48 · 200 in bank
Given the code fragment:
What is the result?
Show answer
Answer: B
Explanation
The answer is B, always remember that Date is immutable, in the third line there was an addition of 10 days in "date" but no variable received this value so the operation was lost there and didn't record anything. And in the print will appear the original date of the variable "date".

Question 49 · 200 in bank
Given:
What is the result?
Show answer
Answer: A
Explanation
The answer is A, when the "++" comes after the variable, the value is added after the line or parentheses as in "x++", but when the "++" comes before the variable, the value is added on the fly as in "++y" then inside the condition we had 1 < 2, giving true and printing Hello on the last line as the two variables already had their value added +1, printed on the screen Hello Log 2:2.
