Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Assume also the maximum number of characters of all file names is 100.arrow_forward

- JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList.

Here is a typical coding pattern for processing each line of a file in turn: Open the file for reading. Use a for loop to iterate over the lines of text, executing a block of one or more statements to process each line. Close the file. Finish processing (print, return, etc.) if needed NOTE: You will need to use this pattern, or some variation of it, to solve the remaining coding problems in this assignment. As the following for loop iterates through each line of the file, the loop variable (`line`) represents the current line of the file as a string of characters. myFile = open("someTextFile.txt", "r") for line in myFile: do something on each iteration do a second thing on each iteration etc... myFile.close() PROBLEM: Read a string from standard input using python.

You need to write code to read in the file data and draw the requested shapes in the correct colour. Each line in scene.txt will contain one of the following starting keywords followed by some data: COLOUR followed by 3 values: R, G, B CIRCLE followed by 3 values: X, Y, RADIUS RECT Followed by 4 values: X, Y, W, H LINE Followed by 4 values: X1, Y1, X2, Y2 CIRCLES are defined from the center. RECT's are defined from the top left. All values are space separated, and you can assume all input is correct (no errors). Please solve this program to draw the scene.
