What is value of the size variable at the completion of this code segment? ArrayList sampleArrayList = new Arraylist(); sampleArrayList.add(new Object()); sampleArrayList.ensureCapacity(25); sampleArrayList.add(new Object()); sampleArrayList.clone(); sampleArrayList.add(new Object()); sampleArrayList.isEmpty(); sampleArrayList.add(new Object()); sampleArrayList.add(new Object()); sampleArrayList.add(new Object()); sampleArrayList.add(new Object()); int size = sampleArrayList.size(); System.out.println(size); Notes: void ensureCapacity(int minCapacity) Increases the capacity of this ArrayList instance, if necessary, to ensure that it can hold at least the number of element specified by the minimum capacity argument. void clone() Returns a shallow copy of this ArrayList instance.

When sorting objects using the Comparable interface, what happens if two objects have the same comparison value in the compareTo() method?

Code to ::::implement a SnapshotArray that supports the following interface: SnapshotArray(int length) initializes an array-like data structure with the given length. Initially, each element equals 0. void set(index, val) sets the element at the given index to be equal to val. int snap() takes a snapshot of the array and returns the snap_id: the total number of times we called snap() minus 1. int get(index, snap_id) returns the value at the given index, at the time we took the snapshot with the given snap_id   Example 1: Input: ["SnapshotArray","set","snap","set","get"] [[3],[0,5],[],[0,6],[0,0]] Output: [null,null,0,null,5] Explanation: SnapshotArray snapshotArr = new SnapshotArray(3); // set the length to be 3 snapshotArr.set(0,5); // Set array[0] = 5 snapshotArr.snap(); // Take a snapshot, return snap_id = 0 snapshotArr.set(0,6); snapshotArr.get(0,0); // Get the value of array[0] with snap_id = 0, return 5...

int [] myArray = {2,3,4,5}: What is the length of myArray? type your answer.

Are they equivalent? 1) ArrayList<?> list = new ArrayList(); 2) ArrayList<? extends Object> list = new ArrayList<>();

Determine if the following statements is true or false. Screen shot shows the text's arraycollection and sortedarraycollection With the text's array-based collection implementation, the set of stored elements is scattered about the array. The text's sorted array-based collection implementation stores elements in the lowest possible indices of the array. When comparing two objects using the equals method inherited from the Object class, what is actually compared is the contents of the objects.
