Which of the following correctly appends a new value specifically to the tail of the following linked list: When one or both array(s) is a string array, When one or more elements in the second array is of a different data type to corresponding element(s) in the first array, When the array size is more than 50 as this requires much time for iteration and comparison of each element, It stops executing in the line where objectArray1 is being declared, The program throws a Data type casting exception error, The two arrays are references to 2 different objects in memory hence not equivalent, The two arrays are found to be equivalent given the fact that they contain the same set of elements, Equivalency check using the comparison operator compares the first array's element to the corresponding element in the second array leading to the two being equivalent, Nodes are all connected, it would result in infinite loop, It is not an array and so a loop is disallowed, Make sure the tail is really the last item, Check to see if the head's next item is zero, Check to make sure the previous element is the tail, Use only the number we're looking for in the array, Find the position of the item we're looking for in the array, Find a sub-array with the results of your search, Use both the number and the index we're looking for, No, the library does all the sorting according to the set criteria, Yes, you have to manually specify the sorting procedure to the library. Core Data uses a schema called a managed object model — an instance of NSManagedObjectModel. Make sure you're ready to take a test or get through a tough assignment by studying this chapter whenever you have time, 24 hours a day. If you use sorting methods contained in the Java library, do you have to code the sorting algorithm? A comparison of two different arrays entails the comparison of a number of things including array sizes and exact contents. A managed object model allows Core Data to map from records in a persistent store to managed objects that you use in your application. We will discuss its uses and provide examples.
