How To Get Program To Perform Tasks Listed In Text File

Feb 12, 2015

This has three different classes in a package and the program itself is supposed to read and perform operations obtained from a txt file. However, I'm not even sure how to get it to perform the operations from the text file. I know that it can read the file as I was able to get the program to print the text found in the file when I ran the program with a test print to make sure that all content was being read. However, I am clueless when it comes to how to get the program to look at the text as commands.

Here is the piece of code that I am not sure where to go from as far as telling the program to read the text and perform the tasks listed.

public static void doTVoperations(){
File operations = new File("operations.txt");
if(operations.exists())
try{
Scanner n = new Scanner(operations);
while(n.hasNext()){
String readOperations = n.nextLine();
String [] command = readOperations.split("[
]");
}
n.close();
}
catch (FileNotFoundException e){
System.out.print("Error...TV in need of repair!");
}

Automated Web Browser To Perform Specific Tasks

Jul 14, 2014

I need to know how to automate a web browser (either Chrome, Firefox or Safari) to perform the following task.

Take a word from a .txt file housed on my hard drive,

1) put it into a search engine,
2) load the results,
3) click on/ open the first result,
4) open up an new tab and perform steps 1-3 again but with the next word from the .txt file. 4-5 second pauses are needed in between each step.

Additionally, I would like to automate the browser to close all the open tabs when a full stop is pulled from the .txt file.

I am using a macbook and 10.6.8 OS.

Read Text File And Perform Operation On Specific Columns

Dec 9, 2011

I am somewhat of a java newbie (learned it awhile back and just getting back to programming some again.) I have a text file of data much larger than this, but here are the first ten rows and first 10 columns.

39755320111041730140.633038085-2.117082366149.069997
39850320111041730150.633038085-2.117082511148.309997
39955320111041730160.633037998-2.117082293149.509997
40055320111041730170.633037945-2.117082351149.239997
.......

I can read and write all the data back out to files. But I am not sure about a few things.

First would it be best to use BufferedReader and OutputStream such as:

public static void main(String[] args) throws IOException {
BufferedReader bReader = new BufferedReader(new FileReader ("testdata.txt"));
BufferedOutputStream bytesOut = new BufferedOutputStream(new FileOutputStream ("outfile.txt"));

Second, I was then going to initialize an array but I might have 30 or more columns of data, of which I might perform and output only 10 columns to my output.txt file so is this a good way?

Third, I only want to perform operations (such as average the data, convert units or multiply two columns together) on 10 of the 30 plus columns and print out results to output.txt file. For example, In testdata.txt file above, I want to skip first seven columns. I then want to take column 8 and multiply by 100 then divide by 3 and output result to output file. I want to do same for column 9. Column 10 I want to multiply by different number (by 3.5).

Program Is Not Reading The Text File

Apr 29, 2014

I'm working on a project for my Java class and I've got the code compiled and running, I just don't think that the program is reading the text file the way I want it to.

The text file looks like this:

1168,4.25,10
1305,1.80,42
1345,12.56,16
1388,7.42,30
1480,6.54,80
1495,8.36,48
1560,15.27,65
...

The first number being product number, second being price, and 3rd being quantity. I want to be able to enter the product number and have the Textfields for price and quantity be filled accordingly.

But when I enter a product number (e.g., '1168') no match for the item is being found, regardless of what I enter. Really stumped on this. Here's my code so far --

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.util.Scanner;
public class Project3
{
private static Frame myframe;
private static TextField productCode;
private static TextField invNumberField;

[Code]...

Java Program That Reads Array From Text File

Mar 19, 2015

I was wondering if it's possible to do this: I want to build a java program that reads a java array from a text file.

Then I want to read it, and output it in a different format.

The reading and out is easy - as text.

But how can I incorporate the read text in to a java valid array in my program, which I can use?

Is this even possible?

GUI Program - Enter File Name And Display Text Area

I have to write a gui program where I can enter a file name and then it gets displayed in a text area when I click Open. Conceptually, I do not get this. I was thinking of appending the text file into a string or something, but I guess I'm confused on how it all works and how I can open the text file. Not asking for the code, but just a compass or something.

How To Make A Text File Only Use Lines In A Text File Beginning With A Certain Letter

Mar 15, 2015

I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.

I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?

Pickup Selected Text File And Read Line By Line And Output Text Into Visual Text Pane

Dec 12, 2014

I am checking how to do following task.

01. pickup the selected text file and read the line by line and output the text in to visual text pane.

what i did:.

01. I wrote code that read the text file and output in to jave console/ also some of the interface.

the code read txt file:

Java Code:

String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){

[code]....

so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?

Swing/AWT/SWT :: JButton Does Not Do All Tasks

Aug 3, 2014

I have a jButton that when the action perform runs it only does part of the tasks some of the code doe not appear to run and i just can not figure out why i have tried wrapping parts of it in an if statement and it still do not run so here is the code behind the button:

in the code the parts that do not run are jTextField10.setText("Working Please Wait"); and jButton15.setVisible(false);

what i am expecting to happen is the text field has the words Working Please Wait placed in it , this does not happen and the button should be hidden to prevent it being clicked a second time again this does not happen

the rest of the code works as expected

InputStream inStream;
OutputStream outStream;
try {
File afile = new File("C://templates//amendments.xls");
File bfile = new File("C://amendments.xls");
inStream = new FileInputStream(afile);
outStream = new FileOutputStream(bfile);

Throttling Submission Of Tasks To A ThreadPoolExecutor

Jun 4, 2014

I have a library that uses a ThreadPoolExecutor, backed by a bounded queue.

We submit a large number of tasks to this executor, constantly polling an external dependency for new work. However, this executor has a fixed size. When a ThreadPoolExecutor is busy, it queues up to the blocking queue's capacity tasks in its blocking queue, at which point it starts rejecting tasks.

What I'd rather do, instead of requesting more work, and then throwing it out, is to detect that we're totally busy and stop requesting work until a thread frees up.

Now, I know that one approach is to rewrite the workers such that they are infinite loops, who poll for work when they're finished. Due to the large number of consumers of this library, this is not an option.

I have come up with two other solutions.

1) This is one that I know will work, which is to use a semaphore or other concurrent counter to track how many tasks I have submitted, and stop requesting more work when that semaphore is out of permits. The processors release a permit when they complete (whether due to exception or success).

2) The other option, since I know this is a ThreadPoolExecutor, is way simpler, but also is something I'm not sure is reliable.

I can compare executor.getActiveThreads() + executor.getQueue.size() to the maximum number we can handle before rejecting (maxThreads + queueSize). This change is far simpler, but I'm not sure if those calls are a reliable way of counting the current work.

Servlets :: Offline Tasks In Java Web Application

Feb 11, 2014

I am on developing a web application (using struts). So most of my web application use cases are reading and presenting data to the users.

But i need to write the another set of programs to keep on reading the data from another data bases and update my database. I have list of timings at which i should read the data from each of other sites (i.e. i know when the other databases gets updated information). Its almost every 20 mins..

Now i want to design the app.

1. Should i include the data read programs as part of my Web application ( means runs in same server JVM) and make the threads as daemon threads..?
2. Should i write another application (offline application) runs out of server in another JVM ?

Prompt A User To Enter Three Tasks And Their Priorities In A Driver

Oct 31, 2014

My full instructions are to Design a Java interface called Priority that includes two methods and two constants. The methods are setPriority and getPriority. The constants are MIN_PRIORITY with value 1 and MAX_PRIORITY with value 6. The interface should define a way to establish numeric priority among a set of objects. Design and implement a class called Task that represents a task (such as on a to-do list) that implements the Priority interface. Assume that Task has two attributes (instance data): name and priority. Define the Task constructor to accept and initialize the name of the task. Each newly created Task should have priority equal to MIN_PRIORITY (the constructor should initialize priority to MIN_PRIORITY). Priorities can be changed using setPriority method. Create a driver class TaskDriver that should do the following: prompt the user to enter three tasks and their priorities, and then print the tasks in the order of decreasing priorities. If the user enters an invalid priority that is less than MIN_PRIORITY or greater than MAX_PRIORITY, then the user should be asked to enter priority again until a valid priority value is entered.

So far I have:

public interface Priority
{
public void setPriority(int level);
public int getPriority();

[Code].....

Read Text File Into Object Array And Creating Random Access File

Dec 8, 2014

I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...

The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data.

Here is the base Product class that must be used to create the objects for the array.

public class Product
{
public String pName;
public String stringName;
public double price;
public int quanity;

[Code] .....

And then here is the data from the text file that i must extract to use to create product objects.

Dill Seed,938,34
Mustard Seed,100,64
Coriander Powder,924,18
Turmeric,836,80
Cinnamon (Ground Korintje),951,10
Cinnamon (Ground) Xtra Hi Oil (2x),614,31
Cinnamon (Ground) High Oil (1X),682,19

These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....
