For this exercise you will design and implement a program that reads and renders a tile map that has been specified in a file that uses the same format you designed for the previous exercise. You will need to handle any exceptions that might arise, attempting to correct any missing data instead of simply terminating or crashing. A sample tileset is available on Brightspace. In order to complete this task, you will need to: • ensure you know how to load an image in pygame and find its dimensions Your submission for this exercise: must be a source code file with filename2 'comp1405_w23_#########_tu • must loop until the user specifies a file name that actually exists must terminate if the file specifies any tile image that doesn't exist must create a pygame window of the correct size and blit the tile images to

The People class holds an unsorted list of humans. Initially, this list is empty. Existing Human objects may be added to the list using an insert method. Upon inserting a Human object, it is added to the array at the next available position and the position value in incremented. If the position value is equal to the size value, do not insert the Human. Instead, throw an exception that your driver can catch to print an error that the People object is full. Create a People class with the following features: Each People object has a statically allocated array of Human objects. Size attribute representing the maximum size of the array. Position attribute representing the next free position in the array. Default constructor with no arguments. Search method that takes a string argument and returns a Human object. This method returns the first Human object with a name matching the string argument. In other words, pass the name of a Human as a string, search the list of humans for…
modify the serialio.c file so that it continuously takes 960 samples, computesthe average, converts the average value to temperature, and prints out the result. you can’t give the buf array as a bufferpointer to read. Instead, you will need to give a pointer to the current position in the buf arraylike &buf[i], where i is the number of bytes that have been read so far. Every time you do theread, you will need to read 960-i bytes to account for the fact that you have already read i bytes.Once you reach 960 bytes, drop out of the loop and calculate the average and the actual temperatureusing the formulas below. After you print the temperature, start again, and get a new 960 samplesof data. Also, whendoing the math, make sure you are doing the calculations using floats or doubles.
Please you need Implement quicksort in a JAVA programming language. The first version will use the first element of the array as the pivot. Please help me with a Java code , It needs to take the input from a file of 100 data elements. Can someone please help me with this coding problem. I have the data set file , but I cannot upload it in here. Kindly help me with the code. ????
In this assignment, you will write a program that readsa list of people from a file, create a HashSet of the people, and print the people in the HashSet.The input filename ispassed in as a command line argument.•The program must implement a main class, and a Person class.•A template for the Person class is provided.A Person has a name and an address, both Strings.•If the input file name is not provided, your program should an error message and exit, e.g., Usage: java FuAssignment10/FuMain inputfile•If the specified input file does not exist or cannot be opened, your program should an error message and exit, e.g.,File abc.txt does not existor cannot be opened!•The input file lists one person per line. Each line contains aname and an address, separated by a comma, “,”.For example, the following are in a sample file students.txt:James Bond, 111 Main StTayer Smoke, 2334 Murry LnDavid Jones, 302 Toast AveAbby Wasch, 84 Sunny PlJames Bond, 111 Main St•Yourprogram should read each line,…
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…
In the Utils class provided to you in this exercise, please fill in the details for a method called swapArray(). You can either upload a file or use the Edit tab to submit your work The VPL tester will pass an arbitrary array of type integer to your method, along with the value of the locations in the array of two values that need to be swapped (exchanged). For instance, in the illustration below, the method swapArray is told to swap the values in positions 0 and 2 of an array made up of (10, 20, 30, 40, 50}. The three input parameters to the method are the array, as well as the two array indices (i and j) that control which elements to swap. public class utils { public static woid wap Array (int[] the Array, int i ,int j){ ex: lo 20 30 40 50 write stuff here Jwap
For this part in the assignment, you need to write a program in python that removes allinstances of a target element in a file named inputFile.txt. The user must enter the instance thatyou need to remove from that file. Once you received that instance, you need to check all thecontent in the inputFile.txt and remove that word. The result will be saved in another file calledoutputFile.txt. For example, if you received that the user wants to remove the word “and”, youneed to identify all the matches and remove them in the outputFile.txt document.Requirements: You should create the content in the inputFile.txt, please make them at leastwith ten lines or more. You could include poems, lyrics, news, etc. It is up to you. Also, youmust use functions to solve this part in the assignment
I need this ASAP I am supposed to you try-catch statements for this code but keep getting an error this is the code i have so far: public class FileIO04{ public ArrayList<String> readFileToArrayList(String filename) throws Exception { File file = new File(filename); BufferedReader buffer = new BufferedReader(new FileReader(file)); String line; ArrayList<String> list = new ArrayList<String>(); while ((line = buffer.readLine()) != null) { list.add(line); } return list; } }
Add preconditions to the methods __getitem__ and __setitem__. The precondition of each method is 0 <= index < size(). Be sure to raise an IndexError exception if the precondition is not satisfied. To test your program run the main() method in the arrays.py file. Your program's output should look like the following: Physical size: 10 Logical size: 0 Items: [None, None, None, None, None, None, None, None, None, None] Traceback (most recent call last): File ".solution/arrays.py", line 69, in <module> main() File ".solution/arrays.py", line 66, in main print(a[0]) File ".solution/arrays.py", line 45, in __getitem__ raise IndexError("Array index out of bounds") IndexError: Array index out of bounds
TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the arrayelements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add tothe array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the front of…
The goal for Lab06b is to use the provided Student class (attached in image) and create an array of Student objects that are stored in a School object(picture of main class attached). This program uses a Student class that is provided and shown below. The class is placed in its own separate file and should not be altered. This program sequence started with Lab06a. It is a reminder that it is the same Student file used by Lab06a. This lab will add data processing to the earlier Lab06a. This program will continue with the Lab06b program that performs some data processing on the Student records. For this lab 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. You actually did this already for Lab06a. You also need to complete the School constructor, addData method and toString Method, which were in Lab06a. Feel free to just copy them over. You need to complete three bubbleSort methods; one that sorts according to the student gpa.,…
The goal for Lab06a is to use the provided Student class and create an array of Student objects that are stored in a School object. This program uses a Student class that is provided See the work area. The class is placed in its own separate file and should not be altered. The Lab06avst.java file is also provided for you in the work area. You will not see the Student class here. There is evidence that the Student class is used, as you see in line 17, but the class is separate in its own file, which is better Object Oriented Design. Specifics and Output 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. The actual data used in the Student objects can be seen by the output below. This program requires the completion of the School constructor. It also requires the completion of the addData method. This method does a lot. First you need to create three initializer lists for names, ages and gpas. These arrays are only used to…
