Question 5 Given the following method to be considered outside the ArrayQueue class. What does this method do? public static void unknown(ArrayQueue q) if (q.isEmpty()) return; ArrayQueue q1= new ArrayQueue(q); while (!q1.isEmpty(0) q1.offer(q.poll0): A q1 will have the same elements as the original q (before changing).

java Create a static method that: is called repeatAll returns ArrayList of Booleans takes in a single parameter - an ArrayList of Booleans This method should modify its ArrayList parameter by repeating its ArrayList values. For example, if the parameter is (true, false, false) The modified ArrayList should be (true, false, false, true, false, false) public static void main(String[] args) { Scanner in = new Scanner(System.in); int size = in.nextInt(); ArrayList<Boolean> list = new ArrayList<>(); for(int i=0; i < size; i++) { list.add(in.nextBoolean()); } System.out.println(repeatAll(list)); } }
Complete the following code for a method that returns true if there is at least one element with a year level that matches a specified ????????????? ???? in an array of objects of the described ??????? class. public boolean practice(student[] aArray, int yearLevelToSearch) { boolean found = false; for (int x = 0; x < aArray.length && !found; x++) { if (_____) { ______; } } } }}
Assume the following method is added to the ArrayQueue class. What does this method do? public void undefined() { if(size < 2) return; if(size == capacity) reallocate(); rear = (rear + 1)%capacity; int f = (front + 1)%capacity; theData[rear] = theData[f]; size++; } Makes the front as rear and the rear as front, if the number of elements in the queue is at least 2. Adds the front element of the queue at the rear of the queue, if the number of elements in the queue is at least 2. Adds the second element of the queue at the rear of the queue, if the number of elements in the queue is at least 2. Exchanges the first and the last elements of the queue, if the number of elements in the queue is at least 2.
The following code is part of the add method in the ArraySortedBag class. What is the missing code? if self.isEmpty() or item >= self.items[len(self) - 1]: <missing code> add.ArrayBag(self, item) add.self(item) ArrayBag.add(item) ArrayBag.add(self, item)
Methods Details: public static java.lang.StringBuffer[] getArrayStringsLongerThan(java.lang.StringBuffer[] array, int length) Returns a StringBuffer array with COPIES of StringBuffer objects in the array parameter that have a length greater than the length parameter. If no strings are found an empty array will be returned. Parameters: array - length - Returns: Throws:java.lang.IllegalArgumentException - When a null array parameter is provided
java Create a static method that: is called appendPosSum returns an ArrayList of Integers takes one parameter: an ArrayList of Integers This method should: Create a new ArrayList of Integers Add only the positive Integers to the new ArrayList Sum the positive Integers in the new ArrayList and add the Sum as the last element For example, if the incoming ArrayList contains the Integers (4,-6,3,-8,0,4,3), the ArrayList that gets returned should be (4,3,4,3,14), with 14 being the sum of (4,3,4,3). The original ArrayList should remain unchanged. public static void main(String[] args) { Scanner in = new Scanner(System.in); int size = in.nextInt(); ArrayList<Integer> list = new ArrayList<>(); for(int i=0; i < size; i++) { list.add(in.nextInt()); } System.out.println(appendPosSum(list));
Define a static void method, which receives as an parameter an array of salaries (of type double) and increases them as follows • salaries <$ 800 - by 10% • 800 <= salaries <= $1500 - by 5% • salaries over $1,500 - by 3% In the test function, define an initialized array of salaries and display it. Call the written method and display the array again.
Write a method that takes a rectangular two-dimensional array of type int. The method returns true if the sum of the even elements of the parameter array are larger than the sum of the odd elements, otherwise the method returns false. public static boolean sum(int[]0 in) Taken array Result 1 -3 17 5 -2 30 true 1 3 -1 -1 -3 -4 7 -1 10 false -1 3 -4 15
