OOP (Object-Oriented Programming) in Java Applying the composite pattern, you may create a replica of any environment you choose. Any number of media may be used, from photographs to simulators to movies to video games, and so on.

Java -  When too many recursive calls are made creating more activation records than the allocated program memory can handle, an “out of memory” error occurs. True or False?

Demonstrate Recursion Assignment Instructions Overview The programs we’ve discussed so far are generally structured as methods that call one another in a hierarchical manner. For some problems, it’s useful to have a method call itself—this is known as a recursive method. Such a method can call itself either directly or indirectly through another method. Recursion is an important topic discussed at length in upper-level computer-science courses. Instructions Write a recursive method printArray() that displays all the elements in an array of integers, separated by spaces. The array must be 100 elements in size and filled using a for loop and a random number generator. The pseudo-code for this is as follows:   //Instantiate an integer array of size 100 //fill the array For (int i=0; i<array.length; i++) Array[i] = random number between 1 and 100 inclusive printArray(integer array);   For this assignment make sure that your screen shots show your program running and that your runtime…
