Write a stream based program which will accept Roll Number, Name, Age and Address from user. Age and Roll-no should be numeric. Handle with built-in exception. None of the field should be blank. Handle with custom exception.

Write a program that updates and displays game stats for football players (Defense) at a local high school. Your program will read a file containing the names and ids of the defensive players. The program will prompt for the following data for each player Number of tackles Number of sacks Number of interceptions Once the stats have been provided, the program will update the player information. After all players have been updated, the program will display details for all players and write the updated information to a new file In Python

Assignment: Exception Handling and Text 10 Problem Statement: Write a program that reads a file named "input.txt" that contains integers separated by whitespace (space, tab, or newline). The program should calculate the sum of all the integers in the file, ignoring any non-numeric values. Requirements: The program should define a class named "FileSumCalculator". The class should have a method named "calculateSum" that takes a file path as a parameter and returns the sum of all the integers in the file. The method should handle any exceptions that might occur during the file reading and sum calculation. The program should print the sum of all the integers in the file to the console. Examples: 1. If the contents of the "input.txt" file are: 123 4 five 67 The program should print: Sum: 23

Write a program that writes a series of random numbers to a file. Each random number should be in the range 1 through 500. The application should let the user user specify how many random numbers the file will hold. Use an exception to make sure that an integer was typed in by the user for the #to generate. If not reask the user for input in the except clause until they input the correct number. You should do this in one function named main

Which file open flag causes the contents of an existing file to be discarded and the file size reduced to zero?

A thrown exception may contain more information about what caused the exception. True or False

Which of the following for-loop correctly reads and prints records (one record per line) that are stored in the file which was successfully opened with the file stream fileIn?  The file contains a list of student records. Each record is stored in two lines; student name and student age are stored in separate lines.          A.     for student in fileIn :name = fileIn.readline().rstrip()age = int(fileIn.readline())print(name, age)        B.     for student in fileIn :name = student.rstrip()age = int(fileIn.readline())print(name, age)        C.     for student in fileIn :name = student.rstrip()age = int(student)print(name, age)        D.     for student in fileIn :name = student age = int(fileIn.readline())print(name, age)

4. Read from File Create a program that reads the values in the temperature data file created in the previous program. The program will display each temperature value in the file and calculate and display the average temperature. Be sure your program handles exceptions.

Assume that there is a data file named as “data.txt”. This data file contains integer values in multiple lines, as shown below. You are asked to write statements in the main() method to open the file, read and print out the total of all the values (should be 55). Place your code into try-catch block so that the FileNotFoundException will be caught and an error message will be printed if no such file exists. data.txt 1 2 3 4 5 6 7 8 9 10 import java.util.*; import java.io.*; public class ReadAndPrint {     pubilc static void main() {         // your code goes here }

Write a Java program to perform the following tasks:The program should ask the user for the name of an input file (scores.txt). Theinput file should contain 10 records. Each record in the input file shouldconsist of a name and score between 0 and 100 (inclusive). Eg: fred 95The program should open the input file as a text file (if the input file does notexist it should throw an exception) and read the contents line by line.Store each record in an array of a user-defined Score class. The Score classcan be kept very simple with 2 instance variables, a default constructor, getand set methods for the instance variables.Now process the array of Score class objects to determine:• The average of all scores• The largest score• The smallest score
