Explain your approach to reading individual bytes from a file
Some of the data may be encrypted by adding 5 to a byte. If encrypted data has a value between zero (0) and four (4), what will the decrypted value be?
GUI Design. Create a wireframe(s) for the GUI (See CRUD table in homework assignment)
Create an
Step by step
Solved in 2 steps
- When importing a Text file, why is it important to move through each step of the Text Import Wizard?You need to make an improvement to the file's organization.Create a new text file using a notepad or any other software, The text file contains your name(first 8 chars) and the file must be exactly 8 bytes in size only and name it “your_ID.txt”.
- Q1.Write a GUI program to let the user enter a file name from an entry field and then count the number of occurrences of each letter in that file. Clicking the Show Result button displays the result in a text widget. You need to display a message in a message box if the file does not exist. Q2.Revise the preceding exercise to display a histogram for the result, as shown in the figure below. You need to display a message in a message box if the file does not exist. PYTHON ONLY!! Thank you! Also, could you add some explanations of your code please.Please help me. Description of what to do is below. A user must be able to enter any phrase or sentence that they would like to encrypt or decrypt Then if you can in a txt file create a gui for that program. An example is below in the photosIf you want to read data from a text file, what kind of object should you create?
- File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will bea version of the first file, but written in a secret code.Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. Write a program that decrypts the file produced by the program in above.The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file.A file exists on the disk named students.dat. The file contains several records, and eachrecord contains two fields: (1) the student’s name, and (2) the student’s score for the final exam.Design an algorithm that changes Julie Milan’s score to 100.Write a program that displays a text file in a text area, as shownin Figure . The user enters a file name in a text field and clicks the Viewbutton; the file is then displayed in a text area.
- The output should be a text file with the final position and the facing direction (no GUI required)PrintWriter and Scanner - text file I/O DataInputStream and DataOutputStream - binary file I/O RandomAccessFile - binary file i/o where every record is the same number of bytes so that you can seek to a specific record ObjectInputStream and ObjectOutputStream - read and write objects.write java code The wise university like to manage Student records uSig a desktop application. The program's main Window includes two options (can be implemented Lßing buttons Ot Similar components). These options are: add a new record and display search and edit records. To implement such an application. you need to implement the following: Create three frames, one as the main application frame Frame) and two hidden frames (add New Record and Display, search and Edit record) that are displayed only through events implemented the mainframe (two buttons). The components Of the secondary windows are follows: Add New Record: use proper components to allow to add the fo"owing information for each student (Name. Gender, University ID. National ID. Nationality, Tawjihi Graduate Year, Major, Academic Department, and Faculty). Note; are not always the right option user inputs When there options for some inputs. Display, and Edit Record: use Components to the user to display the students'…
