For python: Use np.random.rand(5,5) to create a random 5x5 array. Use boolean indexing to set the nine entries in a 3x3 block in the bottom right corner to 0. Print the result. (Hint: Use np.ones() or np.zeros() with the dtype argument to get a 5x5 array full of True's or False's. Use this array to build a boolean filter, in order to set only the entries you want equal to 0.)

Array lists are objects that, like arrays, provide you the ability to store items sequentially and recall items by index. Working with array lists involves invoking ArrayList methods, so we will need to develop some basic skills. Let's start with the code below: The main method imports java.utii.ArrayList and creates an ArrayList that can hold strings by using the new command along with the ArrayList default constructor. It also prints out the ArrayList and, when it does, we see that...

EMULATE A PROCESS CONTROL BLOCK In this assignment you will use Java, Python or C++ to create a process control block. All objects described aren’t provided, you will create them. You can divide up this code into separate files or put all code in one file. Proper documentation is essential, if there are no comments 5% of the total grade will be deducted. The process control block object PCB should have the following fields: ID: a unique ID for this...

In this problem you'll get to use one of Java's random number generators, java.util.Random (see the docs for Random). This class generates a random double precision number uniformly distributed in the range [0.0 ... 1.0). That is, the numbers go from 0 to 1, including 0 but excluding 1. It is a common need in Java programming to generate a random integer number that's uniformly distributed in the range of [0 ... n), such as we saw in the dice...

JAVA Lab Create a class called ArrayBasedStack. Declare the following variables: • data: references an array storing elements in the list • topOfStack: an int value representing the location of the stack top in the array • INITIAL_CAPACITY: the default capacity of the stack public class ArrayBasedStack <E> { private E[] data; private int topOfStack; private static final int INITIAL_CAPACITY = 5; } Add a constructor that will initialize the stack with a user-defined initial capacity. The top of the...

This script will create a dictionary whose keys are all the directories listed in thePATH system variable, and whose values are the number of files in each of these directories. The script will also print each directory entry sorted by directory name. The script will use the following five functions to get the required results get_environment_variable_value() get_dirs_from_path() get_file_count() get_file_count_for_dir_list() print_sorted_dictionary() get_environment_variable_value() The header for this function must be This function must accept a shell variable as its only parameter The...

Lab Topics • The basics of Array object Use the following Coding Guidelines • When declaring a variable, you usually want to initialize it. Remember you cannot initialize a number with a string. Remember variable names are case sensitive. Use tabs or spaces to indent code within blocks (code surrounded by braces). Use white space to make your program more readable. Use comments after the ending brace of classes, methods, and blocks to identify to which block it belongs. Problem...

Store this file in the same folder as your “class” file(s). The format is the same format used in the original homework problem. Each line in the file should contain a pet name (String), a comma, a pet’s age (int) in years, another comma, and a pet’s weight (double) in pounds. Perform the...
