Question 2 Choose the correct answer after considering the following statements: 1. A weak pointer can be used to delete the object to which it points if a temporary shared pointer is created from the weak pointer. 2. Proper use of weak pointers can prevent memory leaks. 3. Weak pointers observe and don't own resources. O Only 1 is true O Only 1 and 3 are true O Only 3 is true O Only 2 and 3 are true O Only 2 is true

In java   Browse Project Gutenberg (https://www.gutenberg.org/) for plain text versions of one or more works of literature of your choosing. Write a program that repeatedly searches a file for a target word or phrase.• Allow the user to supply the name of the file to search by means of a command-line argument; if the user does not supply a command line argument, ask for a file name interactively.• You may use either an array or an ArrayList to store each line in the file; but if you use an array, you’ll have to determine the array size (number of lines) before allocating the array. There are several ways to do this.• Report how many lines were read from the file.• Search for either individual words or phrases (Hint: use the .contains method, it’ll work for either a word or a phrase)• Show both the line number and the line itself for each line that contains the search target entered by the user (you may count the first line in the file as line 0).• If a search word is part of a larger…

28.  Which statement of the following is the most appropriate? Group of answer choices The size of a dynamic array needs to be determined at compilation. Such behavior, determined at compile time, is called dynamic behavior. Dynamic behavior is more flexible than decisions that are made at run time (i.e., static behavior).   The size of a dynamic array does not need to be determined until a program is running. Such behavior, determined at run time, is called dynamic behavior.
