Question

Java Netbeans. Write an application to do the following: a. Create a file "student.txt". b. Ask the user to enter the students information such as id and name. c. Use FileWriter and BufferedWriter to write this information in the file. d. Read the information from the file using appropriate classes and e. Display the information on the screen. f. Import the classes required in the program.

Answer 1

The question is about writing a Java application in NetBeans to handle file I/O operations, such as creating a file, writing user input to it, and reading and displaying its contents.

Step-by-step explanation:

The student is asking for an application to be written in Java using NetBeans IDE that will perform the following tasks:

• Create a file named student.txt.
• Prompt the user to enter student information such as id and name.
• Use FileWriter and BufferedWriter to write this information into the file.
• Read the information from the file using appropriate classes like FileReader and BufferedReader.
• Display the information on the screen.

To accomplish this task, the program needs to import Java I/O classes such as FileWriter, BufferedWriter, FileReader, and BufferedReader.

Example:

In Java, such an application would typically start by importing the necessary classes at the beginning:

import java.io.FileWriter;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.File;
import java.util.Scanner;

Then the program would follow the logic to create the file, write to it and read from it based on the user's input. The key elements in the program are creating the 'student.txt' file, writing user input to it, and reading and displaying the contents.
