For this assignment, you will develop "starter" code. After you finish, your code should access an existing text file that you have created, create an input stream, read the contents of the text flie, sort and store the contents of the text file into an ArrayList, then write the sorted contents via an ouput stream to a separate output text file. Copy and paste the following Java™ code into a JAVA source file in NetBeans: import java.io.BufferedReader; import java.io.BufferedWriter; public class Datasort { public static void main (String [] args) { File fin = // input file File fout = // create an out file // Java FileInputStream class obtains input bytes from a file FileInputStream fis = new FileInputStream(fin); // buffering characters so as to provide for the efficient reading of characters, arrays, and lines BufferedReader in = new BufferedReader(new InputStreamReader(fis)); // declare an array in-line, ready for the sort String aLine; ArrayList al = new ArrayList (); int i = 0; while ((aLine = in.readLine()) != null) { // set the sort for values is greater than 0 Collections.sort(al); // sorted content to the output file { System.out.println(s); } // close the 2 files } } Add code as indicated in the comments. ...

Java.io.File Class in Java. The File class is Java's representation of a file or directory path name. ... A file system may implement restrictions to certain operations on the actual file-system object, such as reading, writing, and executing. These restrictions are collectively known as access permissions. The program uses console I/O to simply read its "standard input (stdin)"—which might be the keyboard, a file dump, or the output of some other program—and print to its "standard output (stdout)"—which might be the display or printer or another program or a file.

JAVA Q2: Write a program that reads strings from the user and writes them to an output file called userStrings.txt. Stop processing when the user enters the string \"DONE\". Do not write the sentinel string (\"DONE\") to the output file. [15 points] Hint: For a complete example of file IO, please see the attached TestData program. Sample Output: A string. Another string. Yet more text... DONE Solution Answer import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.util.Scanner; class WriteStringFile { public static void main(String[] args) { File file = new File(\"D:/userFile.txt\"); String data; Scanner input = new Scanner(System.in); data = input.readLine(); try (FileOutputStream fop = new FileOutputStream(file)) { // if file doesn\'t exists, then create it if (!file.exists()) { file.createNewFile(); } if (data != \"DONE\") { // get the content in bytes byte[] contentInBytes = content.getBytes(); fop.write(contentInBytes); fop.flush(); fop.close(); } else { System.out.println(\"User Enter the value Done..
