Before using the ReadLine function on a StreamReader object, it's important to make sure the property's value isn't set to "true" (meaning the object has reached the end of its stream).
Step by step
Solved in 2 steps
- When using the ReadLine function on a StreamReader object, it is important to determine whether or not the object has reached the end of its stream by looking at its EndOfStream property.As a precaution, before using ReadLine on a StreamReader object, you should examine its EndOfStream attribute.The ReadLine method of a StreamReader object shouldn't be called until the EndOfStream property has been checked.
- Why should you check the value of a StreamReader object’s EndOfStream property before calling the ReadLine method?(C#)Assume inputFile references a StreamReader object that is associated with a file that is already open. Which statement can read all the items in the file without knowing how many items the file contains? Question 9 options: while (!inputFile.EndOfStream) { } while (inputFile.EndOfStream) { } while (inputFile != EndOFStream) { } while (inputFile == EndOfStream) { }Assume inputFile references a StreamReader object that is associated with an open file. Which of the following loops is written in the correct general format to read all of the items from the file? Loop A: while (inputFile.EndOfStream) { // Read an item from the file. } Loop B: while (!inputFile.EndOfStream) { // Read an item from the file. }
- Output to a file can be achieved with a _____ object, which is constructed with a File and has the same methods as System.out (the class name is case sensitive)(Just Words)File redirection allows you to redirect standard input (keyboard) and instead read from a file specified at the command prompt. It requires the use of the < operator (e.g. java MyProgram < input_file.txt) True or FalseHow to code this assignment JSON objects. Hint: Work on the methods in the order they are found in the documentation below. def read_last_line(file_path: str)->str: """ Reads the last line of the file at the specified file path. The function returns the last line of the file as a string, if the file is empty it will return an empty string (""). :param file_path: A path to a file :return: The last line of the file """ def read(file_path: str)->str: """ Reads the entire file at the specified file path. The function returns all the text in the file as a string, if the file is empty it will return an empty string (""). :param file_path: A path to a file :return: All the text in the file """ def write(file_path:str, text:str=''): """ Clears the file at the specified file path then writes the specified line to the file. If the function is invoked without a line parameter or the line variable is None nothing is written to…
