PRG 421 Week 3 Individual Assignment Coding a Program Containing Manipulating Data with the Java™ Stream AP

Regular price $10.00

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:





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<String> al = new ArrayList<String> ();


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





 // close the 2 files





Add code as indicated in the comments.

Note: Refer to this week's Individual assignment, "Week Three Analyze Assignment," and to Ch. 8, "IO," in OCP: Oracle® Certified Professional Java® SE 8 Programmer II Study Guide.

Run and debug your modified program in NetBeans until it satisfies the requirements described above.

Save your finalized JAVA file with a .txt extension.

Submit your TXT file to the Assignment Files tab.
