Given the code snippet from a compiled Java source file:
and this output:
Which command should you run to obtain this output?
Answer: C
The correct answer is C, args3 is equal to the value in the 2nd place of the list, but since Java indexes from 0, when executing the code, the "2" needs to be the 3rd argument, and the same is third in the answer C.

Given the code fragment:
What is the result?
Answer: D
Was confused on this one so an explanation in case anyone else is stuck! Because case "sat" doesn't have a break statement it then falls through the rest of the cases until it reaches a break. Therefore it hits the case "sun" statement, performs the subtraction of 1 and then breaks. So as it loops you get: Sun (wd=-1), Mon (wd=-2), Wed (wd=0), Sat (wd=-1)

Given the code fragment:
What is the result?
Answer: C
C. HiHowAreYou removed System.out.print(s) will print all the elements in array list and return s.length() arrList = new ArrayList<>(Arrays.asList(arr)); if (arrList.removeIf(s -> { System.out.print(s); return s.length() <=2;})) { // System.out.println(arrList); //you can uncomment this print statement to see Hi getting //removed from arraylist. System.out.println(" removed"); } } }

Given the code fragment:
What is the result?
Answer: A
The right answer is the letter A, remember that String is immutable, the "concat" method inside the for each as it didn't receive a variable wasn't storing anything, so it didn't change. And then at the time of printing, it printed A B because nothing has changed. NOTE: To concatenate a String variable, it would have to be -> | strs[idx] = strs[idx] + " element " + idx; | Instead of what's in the code.

What is the result?
Answer: E
class MyException extends RuntimeException { }; public class Test { public static void main(String[] args) { try { method1(); } catch (MyException ne) { System.out.print("A"); } } public static void method1() { try { throw 3 > 10 ? new MyException() : new IOException(); } catch (IOException ie) { System.out.println("I"); }catch(Exception re ){ System.out.println("B"); } } }

Answer: CDF
Given the code fragment:
Which two modifications enable the code to compile? (Choose two.)
Answer: BC
in this case the only two good ones represent its A and B, the Implementation of an abstract method in the child class can be private in note case it does not prevent the compilation, instead the method revolve and declared protected so the child class this method can be declared minimum protected or lower public, thus the answer and A, B
