I have an issue trying to read a file. Iam getting a file not found ex, but the file seems to be there.
This is my project
This the code that is loading the file.

I am trying to create executable jar file and I have test.mf file located in the dir from where jar cmd(JavaTest) is executed and also in dir which contains class files (jTest).
C:Users

java.io.FileNotFoundException: test.mf (The system cannot find the file specified)

So how can Icreate manifest file and where shall I put it ?
Well I fixed my invalid path problem
Now it is telling me that my file is not found and it is exactly where I put it and told JCreator to look for it.
this is what I get:
javac: file not found: C:Program FilesJavajdk1.8.0docsMyName.java
when I go manually to the address, it is there but for some reason Jcreator cannot find it.
I'm getting this -file not found- error despite the fact that I have saved the file with appropriate permissions in the src folder of the given application in netbeans. The program prompts for a listings.txt file to read and write data to a new file that counts and sums the info in a overview.txt report. Here is the stacktrace:

Whenever I try to write a file to the disk and then load it within the same Class (if it is even possible) ...
It gives me an error: Could not find the main class: score.Score. Program will exit.
I have tried this with 2 different classes and it works fine? Why that error is appearing.
Code:
package score;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.FileWriter;
import java.util.Scanner;
public class Score {
public static void main(String [] args) throws Exception

I am working on a magic square program. My program compiles. However, when I enter the square dimension it does not select the correct file. The error says "java.io.FileNotFoundException." It looks like it inserts 0 instead of the entered dimension.

For an assignment I need to read an input text file and evaluate the triangle based on the data found in the text file which consists of an unknown number of groups of 3 numbers (Each group representing a different triangle). According to the project specifications I need to have a main method and several other methods. I have the main method set-up to receive data correctly but I am confused as to how I would get the values out of the text file and use them in the main method. For example, if I were to call the computePerimeter method in my main method, how would I make sure I get the correct perimeter for the given data?
Here is the code I have so far:
import java.io.*;
import java.util.Scanner;
public class TriangleEvaluator
{
public static void main(String[] args) throws FileNotFoundException
{
Scanner in = new Scanner(new File("triangleData.txt"));
double s1;
double s2;
double s3;
while (in.hasNextDouble())
[Code] ....
import java.util.Scanner;
public class Arraykey {
public static void main(String[] args) {
System.out.println("Enter array size: ");
Scanner input = new Scanner(System.in);
int size = input.nextInt();
int [] a = new int[size];
for(int i=0 ; i<size ; i++){

I am assigned to create a program "Simpletron" that the only language understands it is Simpletron Machine Language or SML. I figured out the most but I get the message "No main methods, applets, or MIDlets found in file" when compiling the program. I pasted my program so that you can see.

I have a large text file of 1 GB size. I need to print the line when a matching word is found in a particular line. Below is the code I am using. But if there are many lines that has the matching word, it's taking lot of time. Any solution to print the lines much faster.
Scanner scanner = new Scanner(file);
while (scanner.hasNextLine()) {
String line = scanner.nextLine();
if(line.contains("xyz")) {
System.out.println(line);
}
}
I have a jar file.and i imported its classes to my program..
let say i have a code
source code is at /home/t_bmf/Java/src
import firstjar.FirstJarPrint;
public class TestJar {
public static void main(String[] args) {
//FirstJarPrint jar = new FirstJarPrint();
}
}
well i have successfully compiled it using command below:
javac -cp ".:/home/t_bmf/Java/lib/FirstJar.jar" -d /home/t_bmf/Java/bin TestJar.java
it means that i don't have any compilation error right?so all classes found properly.But whenever I run the program I always got this error:
java -cp /home/t_bmf/Java/lib/FirstJar/jar:. TestJar
Exception in thread "main" java.lang.NoClassDefFoundError: firstjar/FirstJarPrint

I think it has to be no error since i have compiled the program successfully right?if it really didn't find the class, then it must be a compilation error right?
is there something wrong with the way I execute the program?
note: i created the program in UNIX

View Replies View RelatedWrite a program to calculate sales and visually display. An online Cowboy retailer sells five products whose retail prices are as follows:
Product 1: Cowboy Boots, $74.99
Product 2: Wranglers, $25.99
Product 3: Cowboy Hats, $24.95
Product 4: Chaps, $ 34.89
Product 5: Spurs, $12.50
Write an application that reads the quantity for each product until user has completed their order. Your program should use switch, if, for, while and do while statements to read, calculate and display the total retail value of all pro ducts sold for each user transaction. The user should be able to start a new transaction after the first transaction is completed. The user can make no more than 3 total orders
public class Merchandise {
private int bootsQTY;
private int wranglersQTY;
private int hatsQTY;
private int chapsQTY;

When I run my program all of my quantities and the total are 0, I have been stuck for a while trying to figure out how to get values assigned to them...

I am writing a Twitter app, and I am encountering an error whenever I attempt to find the user's name from a screen name. I get the following error:
04-10 21:43:57.402: W/System.err(9326): No authentication challenges found
Which means that somehow, I'm not logged in. However, I am able to post, get the timeline statuses and even get the User of each status. I simply cannot do this:
public String getUserFromScreenName(String screenName) throws TwitterException {
m_twitter.verifyCredentials();
return m_twitter.showUser(screenName).getName();
}
The m_twitter.verifyCredentials() PASSES, which means I am authenticated, and the following line somehow I am not.
My m_twitter is defined here:
public void authenticate(String token, String secret) {
m_accessToken = token;
m_accessSecret = secret;
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setOAuthConsumerKey(m_consumerKey)
