PrintWriter Using FileWriter As Parameter

Oct 24, 2014

How to write a new file:

import acm.program.*;
import java.io.*;
import java.io.PrintWriter.*;
import acm.util.*;
import javax.swing.*;
public class PrintWriter extends ConsoleProgram {

public void run() {

try {
PrintWriter wr = new PrintWriter( new FileWriter ("hello.txt") ) ;
wr.println("Hello world!");
wr.close();
} catch (IOException er) {
println("File could not be saved.");
}
}
}

(I added the imports at top myself.) However, I am getting compiler errors for the lines: PrintWriter wr = new PrintWriter( new FileWriter ("hello.txt") ) , which says that the constructor PrintWriter( FileWriter ) is undefined, and
wr.close();, which says close() method is undefined.

Pretty sure the only real problem is that PrintWriter is not accepting the FileWriter as constructor, but I don't see why. I have tried this on machine with JRE 1.4 and it worked as expected, creating new file titled "hello.txt", prints line of "Hello world!" in that file, and saves it to the directory I picked in the dialog. But I can't get it to work on this machine that uses Compiler 1.6, Java Runtime v8u25.

I have also tried using just a string in the parameter for PrintWriter, such as PrintWriter wr = new PrintWriter ("hello.txt") , and from what I can tell by reading the java spec for java 8, this should work. [URL] .... But I get error message for that constructor as well.

FileReader And FileWriter

Jul 12, 2014

I want to read in a text file(list of Names) using FileReader than Write to another file using FileWriter. Using FileWriter, I only want to write the Name starting with F to a new text file. I have the file reading from one text than writing to another text. The tricky part is filtering the names starting with only F.

Write Hashset To Txt Using Filewriter

Mar 23, 2015

I am trying to write a hashset to a text file. Normally, I have no issues with writing to txt as it is simple for me. However, in this case I am absolutely clueless.

A bit of background about the class: it is a hashset of ComputerScientist objects with 2 fields; name, and field of research (and yes, I know what I put to fill up the HashSet does not count, I was only trying to test to see if I could get this to work).

I know the basic setup to use filewriter to save strings to a txt, but I am getting confused with the HashSet element of it.

import java.util.HashSet;
import java.io.FileWriter;
import java.io.IOException;
/**
* Write a description of class ComputerScientistSet here.
*/
public class ComputerScientistSet {
private HashSet<ComputerScientist> computerScientistSet;

Implement Filewriter To Code

Apr 27, 2014

Ive been trying to implement the Filewriter to my code. What I want is to have the textfield data written to a text field. Im thinking you have to specify the text field you want to have in the filewriter statement,I've done something like this, Ive used the try catch block.

if (source == jBPay) {
System.out.println("Pay");
{
double dOrderTotal = dTotal*1.2;
jTTotal.setText(Double.toString(dOrderTotal));
jTTotal.setHorizontalAlignment(JTextField.CENTER); // align text field centre
jTotal.setText(String.format("%.2f", dTotal)); // set pay text field to 2 decimal place

[code]...

FileWriter - Method Append Is Not Applicable For Arguments

Jun 7, 2014

I am having a bit of difficulty understanding/Using FileWriter. Now by my understanding in the API FileWriter allows to use write at the end of your file, if you have text in there already, correct?

I have a file with people info in it. And I created a GUI which allows people to input that data.

Java Code:

File file = new File("People.txt");
FileWriter fw = new FileWriter(file);
People p = new People(firstName, lastName, email, sex));
fw.append(p);
fw.close() mh_sh_highlight_all('java');

Now, I keep getting an error on the fw.append(p)

Java Code:

The method append(CharSequence) in the type Writer is not applicable for the arguments(People) mh_sh_highlight_all('java');

You are given a file containing the names and addresses of company employees from many years ago that your manager has asked you to import into a database. You can use a CSV file and your database application to load the file, but the file your manager gave you was exported from an old, non-standard accounting system. Here is its format:

Fred|Flintstone

PrintWriter Only Prints Last Line?

Dec 6, 2014

I'm tyring to print the same output in console to a text file, but I can only get the last line of the console output in the text file, not sure what is wrong with my code:

while (in.hasNextLine()) {
PrintWriter writer = new PrintWriter("output5.txt");
tempS = in.nextLine().toLowerCase();
System.out.println(wp.bestPages(tempS));

[code]....

What's causing only the last time to be printed in text file? Are there better ways to print console outputs into a text file than PrintWriter?

PrintWriter Not Working On Servlet?

Apr 12, 2014

I've written a simple html/servlet program that has a user enter their name and password on a form and then either register or login using a submit button. I have the program working, except when a user doesn't fill in either of the text fields I can't figure out how to get it to print to the page. Right now I just have it printing to my Eclipse console which is not what I want. What am I missing?

HTML code:

Writing Data To A File Using PrintWriter

Oct 25, 2014

I am creating a car simulator that simulators the odometer and fuel gauge on a car. I want to print the results to a text file but it seems to be printing only the last two lines instead of all of them. How can I make it so it doesn't overwrite the previous input?

Here's my main method:

CarInstrumentSimulator carInstrumentSimulator = new CarInstrumentSimulator();
FuelGauge gas = carInstrumentSimulator.new FuelGauge();

PrintWriter Not Working - FileNotFound Exception

Dec 8, 2014

I have done lots of PrintWriting before but this is the first time I have done it on my new computer and I'm having an error I haven't seen before. This is my code:

Rprint(){
try {
PrintWriter pout = new PrintWriter(new FileWriter("‪C:UsersJackDocumentsexample.r "));
pout.println("nums = c(1,2,5,6,8,10)");
pout.println("nums");
pout.close();
} catch (IOException ex) {
System.out.println("Error!");
Logger.getLogger(Rprint.class.getName()).log(Level .SEVERE, null, ex);
}
}

*** java.io.FileNotFoundException: ‪C:UsersJackDocuments
This.txt (The filename, directory name or volume label syntax is incorrect) ***

I have a feeling it may be to do with permissions, because it lets me print simply ("example.r") into my project folder.

PrintWriter - Ask User For The Names Of Two Files

Jun 30, 2014

Write a program that asks the user for the names of two files. The first file should be opened for reading and the second file should be opened for writing. Ihe program should read the contents of the first file, change all characters to uppercase, and store the results in the second file. The second file will be a copy of the first file, except that all the characters w ill be uppercase. Use Notepad or another text editor to create a simple file that can be used to test the program

Here is my code. I Also made two text document files that are located in the same directory as the .class file (the code file) that are named OriginalFile and UpperCase respectively. Please let me know what I need to do. Here is the code.

import java.util.Scanner;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
public class UpperCaseFile
{
public static void main (String [] args) throws IOException
{

Non-Parameter Constructor Calls Two Parameter Constructor

Apr 19, 2014

I was practicing my java skills and came across an exercise in which a non parameter constructor calls a two parameter constructor. I tried a few searches online but they all came back unsuccessful. This is the part I am working on:

public PairOfDice(int val1, int val2) {
// Constructor. Creates a pair of dice that
// are initially showing the values val1 and val2.
die1 = val1; // Assign specified values
die2 = val2; // to the instance variables.
}
public PairOfDice() {
// Constructor that calls two parameter constructor
}

I tried calling the two constructor using the line "this(val1, val2)" but I get an error because val1 and val2 are local variables.

Then I tried to use the same signature: "this(int val1, int val2)" but that didn't work either.

PrintWriter Creates File But Doesn't Print File

Nov 7, 2014

This is a college course assignment that consists of classes TotalSales and TotalSalesTest.In the main program I have created a two dimensional array to output a columnar layout with cross-totals in 4 rows and 5 columns. This program outputs sales totals by row for each sales person(1 - 4) and output by column for products(1 - 5). I have created extra elements in the array to store total for rows and columns. So far both classes compiles. The problem is that although the PrintWriter creates a notepad file, it doesn't print to it. I don't seem to understand the input and output methods completely. I finished another program similar to this using basically the same try and catch that read the file and printed out a document in notepad. Here is the code and I'll try include the input file.

import java.util.Scanner;
import java.io.*;
public class TotalSales {
private int salesPerson; //declare class variable
private int productNumber;//declare class variable

JSP :: Getting Parameter Dynamically?

Mar 30, 2014

I'm displaying a 3-column table with the column names ID, name, and salary. I made the ID into a link to go to the EditServlet class. What I'm trying to do is figure out which ID# was clicked to get onto the servlet page, how to implement that dynamically?

I know that if you put something like ?x=1 and then getParameter("x") on the servlet page would work, but then all the IDs would have the same parameters since I'm using a for loop to print out my ArrayList of objects.

My code for the jsp part is below.

for (int count=0; count<list.size(); count++) {
%>
<tr>
<td> <a href="EditServlet"><%= list.get(count).id %></a>
<td> <%= list.get(count).name %>

Passing A Map As Parameter

Apr 30, 2014

I'm using Java in BlueJ where I'm trying to write a class to store cycling club membership details in a map. I'm trying to pass a map as a parameter to a function that will iterate over the map and print out the member details. My code is:

public class CtcMembers
{
//instance variables
private Map<String, Set<String>> memberMap;
/**
* Constructor for objects of class CtcMembers

[Code] ....

When I execute the following in the OU workspace:

CtcMembers c = new CtcMembers();
c.addCyclists();

I can see a map populated with the expected details.

When I execute the following in the OU workspace:

c.printMap(c.getMap());

I get the following error:

java.lang.ClassCastException: java.util.HashSet cannot be cast to java.lang.String
in CtcMembers.printMap(CtcMembers.java:81)
in (OUWorkspace:1)

I wasn't aware I was trying to cast anything so this has got me baffled.

Passing Object As Parameter?

Aug 8, 2014

i want to pass an object of type Software to assign it to a computer from Computer class...

i should note that computer and software are arrays of objects thats the variable and method to set software in Computer class

private Software[] software;
public void setSoftware(Software software,int index){
this.software[index]=software;}

note: the user choses the a computer from a list and a software as will

for example the program will show the user 2 computers

0 for computer: apple, Model: mac mini, Speed: 2.8

1 for computer: sony, Model: vaio, Speed: 2.2

the user enters the index he wants then the program will show a list of software to add to the computer selected

the error I'm having is run time error Exception in thread "main" java.lang.NullPointerException and it points to these 2 lines

1.comp[Cch].setSoftware(software,Sch);

2. the method setSoftware

every thing is running correctly but this step above

Cch= the chosen computer index

Sch= the chosen Software index

why am i getting an error and how to fix it?
