Given the code fragment from three files:
Which code fragment, when inserted at line 2, enables the code to compile?
Answer: E
Incorrect question: if class name of public class is USMarket then file can't have name Market.java If we rename public class or file - correct answer "E"

Given these classes:
and this main method:
Which two options compile when placed at line n1 of the main method? (Choose two.)
Answer: BF
BF are correct. 1. The type of the object determines which properties exist within the object in memory. 2. The type of the reference to the object determines which methods and variables are accessible to the Java program. class Employee{ public int salary; } class Manager extends Employee{ public int budget; } public class Director extends Manager{ public int stockOptions; public static void main(String[] args) { Employee employee = new Employee(); Employee manager = new Manager(); Employee director = new Director(); // director.stockOptions = 1_000; // Compilation Error employee.salary = 50_000; // manager.budget = 1_000_000; // Compilation Error // manager.stockOption = 500; // Compilation Error // employee.budget = 200_000; // Compilation Error director.salary = 80_000; } }

Given:
What is the result?
Answer: C
The answer is the letter C and I will explain, this type of question I already noticed by the simulated ones that falls a lot in the OCA exam, you can't make additions with "++" operators like "++count" or "count++" in a static method with a normal instance variable. For the code to compile, the "count" instance variable must be static.

Given:
And the code fragment:
What is the result?
Answer: A
Given the code fragment:
What is the result?
Answer: B
Given:
What is the result?
Answer: D
The answer is the letter D, very calm pay attention that static variables can only store one value, the last value stored was 6 so the variable "J" of all objects "X" will have the value 6. The only thing I emphasize is be careful when decorating questions, because I've seen a question almost like this one, the only thing that differs is the number assigned to "j", always try to understand how the code works instead of decorating it, this way eliminates the chance of making mistakes and easily solve similar questions...

Given the code fragment:
And given the requirements: 1. Process all the elements of the array in the reverse order of entry. 2. Process all the elements of the array in the order of entry. 3. Process alternating elements of the array in the order of entry. Which two statements are true? (Choose two.)
Answer: BD
Given:
What is the result? A.
B.
C.
D.
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
The answer is the letter D, if you don't give a variable a value, it will have the default value. Character -> Default value is null Boolean -> Default value is false Float -> Default value is 0.0 OBS: Do not memorize the results of the questions, because there are similar questions, this one for example has a variation that changes "Character" for "char", a variable type "char" does not print anything instead of null. Try to understand how the code works, so you'll get it right when a similar question falls on the test.

Given:
What is the result?
Answer: E
The answer is the letter E. Here is the code: public static void main(String[] args) { String [] [] chs = new String[5][2]; chs [0] = new String [2]; chs [1] = new String [5]; int i = 97; for (int a = 0; a < chs.length; a++) { for (int b = 0; b <chs.length; b++) { chs[a] [b] = "" + i; i++; } } for (String[] ca : chs) { for (String c : ca) { System.out.print(c + " "); } System.out.println(); } }
