How to work with files in java?
Java provides the File
class to create, read, update, and delete files.
Example:
File myFile = new File("filename.txt");
Solution:
Using FileWriter
and Scanner
to write and read from the file:
FileWriter writer = new FileWriter(myFile);
writer.write("Hello, World!");
writer.close();
Scanner scanner = new Scanner(myFile);
while (scanner.hasNextLine()) {
System.out.println(scanner.nextLine());
}
scanner.close();
