PARTICIPATION ACTIVITY 8.5.5: Arrange the code to read one line of input at a time and then scan the line with another scanner. Consider a file that contains student grades such as the following: Jane Lee Aaron X. Schmidt Frank von Tardy As with the country names, the student names don't have a fixed number of words. To process the input, read one line of input at a time from the given scanner in, then scan the line with another scanner. Add all but the last word from the line to the name, and set the grade to the last word. 100 37 2 Mouse: Drag/drop Keyboard: Grab/release spacebar (or Enter). Move 0000.

write program code in java: Write a program that reads two files “Data1.txt”, “Data2.txt”; Then add their corresponding elements and produce an output file “output.txt”. If the number of elements are not equal, fill the elements of the smaller file up with “0” s. Sample output: Elements of the “Data1.txt”: 3 5 7 8 9 Elements of the “Data2.txt”: 45 11 Elements of the “Output.txt”: 48 16 7 8
09.Write a program that reads in a set of coin descriptions from a file. The input file has the format coinName1 coinValue1 coinName2 coinValue2 ...Add a method void read(Scanner in) throws FileNotFoundException to the Coin class of Section 7.2. Throw an exception if the current line is not properly formatted. Then implement a method static ArrayList<Coin> readFile(String filename) throws FileNotFoundException In the main method, call readFile. If an exception is thrown, give the user a chance to select another file. If you read all coins successfully, print the total value.
Project Details: Your program should read in a random word from a file called words.txt (note the lack of capitalization) that you provide. The file should contain one word per line. To read a random word you can generate a random number between 1 and the number of lines, and skip n-1 lines before reading the word. Scramble the word by swapping random pairs of letters a random number of times. Display the scrambled word with character indexes on top. Offer the user a menu with the following choices: • Enter 1 to swap a pair of letters If this option is selected prompt the user to enter two indexes and swap the letters. Print an error message if the indexes are invalid. If the word is unscrambled successfully print a congratulatory message containing the word and the number of steps it took to unscramble. Otherwise display the new word, and offer the menu again. • Enter 2 to solve If this option is selected print the unscrambled word and quit. • Enter 3 to quit If this option is…

1. Write a program that reads student scores from a file and then writes the scores with a corresponding grade to another file. Assume integer scores whose valid range is 0–100. An invalid score will be given the grade X. Use a function to assign a grade based off the grading scale below. 90 – 100% A 80 – 89% B 70 – 79% C 60 – 69% 0 - 59% F a. Create a file named scores.txt. Place it in the same folder as your C program. Fill it with the values below. 95 30 65 500 b. Ifa wrong input file name is entered, an error message should be displayed, and your program should stop with no output file created. c. Ifa correct input file name is entered, the program should ask you for the name of the output file and then fill it with the right values as shown in sample output 2. Once done, it should display a message in the main program letting the user know that data has been saved to the output file. Please note that the values in green in sample output 2 would be the contents of the output file…
Write a script file to play a simple number guessing game as follows. The script should generatea random integer in the range 1, 2, 3, . . ., 14, 15. It should provide for the player to makerepeated guesses of the number, and it should indicate if the player has won or give the player ahint after each wrong guess. The responses and hints are as follows:• “You won” and then stop the game.• “Very close” if the guess is within 1 of the correct number.• “Getting close” if the guess is within 2 or 3 of the correct number.• “Not close” if the guess is not within 3 of the correct number.
