I have installed software Net-bean 7.4 and it's working, Now i want to compile and run individual program through command line, I mean where i can find java & javac file under the netbean software, so i am able to do this.
View Repliesi would like to ask what does exactly do the command mvn compile. What is happening with the code, when i write this command? And why is it necessary for running the code?

I'm trying to compile one of my Selenium WebDriver .java files to run from the command line. Since it's just one file, I only need to compile the file into a .class file to run it from the cmd line. I don't need to make a .jar file.
The .java file runs fine inside Eclipse, so now I need to make it run from the windows command line.
I tried compiling it using
javac -classpath C:WDJarFilesselenium-server-standalone-2.42.2.jar TasksCreateAssignments.java
but got this error
TasksCreateAssignments.java:23: error: package org.apache.poi.hssf.usermodel does not exist
how can I can fix that?
I'm creating a program that will compile and run another java program:Lets say I have a program in directory
D:HelloWorldsrc
and compiled program will be in
D:HelloWorldin
inside src and bin is a folder hello (that's a package)
package hello;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
System.out.println("Hello World");
}
}
This program will be run by another program (that's the program that I am creating).Here is the code of my program:
package runnercompiler;
import java.io.IOException;
import java.io.InputStream;
import java.util.logging.Level;
import java.util.logging.Logger;
public final class RunnerCompiler {
[code]....
I created Myproject folder. Inside I have 3 folders:
/lib
/src
/bin
Inside src there is a .java file:
public class hello_world{
public static void main(String[] args){
System.out.println("Hi, from hello_world");
seba.st.hello_world_package test1 = new seba.st.hello_world_package();
test1.packFunc();
}
}
inside lib is a packEx.jar file which I created from this .java file:
package seba.st;
public class hello_world_package{
public void packFunc(){
System.out.println("hi from pack_func!");
}
}
I am trying to run this program from terminal with this command
javac -d bin -sourcepath src -cp lib/packEx.jar src/hello_world.java
and I get this error:
src/hello_world.java:11: error: cannot find symbol
test1.packFunc();
^
symbol: method packFunc()
location: variable test1 of type hello_world_package
1 error
What am I doing wrong ? How can I compile and run this program from terminal?
i wrote this program:
class hellojava
{
public static void main(string[] args)
{
system.out.println("hello java");
}
}
Then i saved this file with name hellojava.java(notepad) in C drive in separate folder c:myjavaapp(not in c:java folder).
When I am compiling(with javac hellojava.java) it shows following error:
cannot find symbol public static void main(string[] args), and also says package system doesnot exists system.out.println("hello java");
I am trying to read contents from a file and display them to the user. However, when I enter the file into the program I get the following error: "exception in thread 'main' java.util.MismatchException. What am i doing wrong?
import java.util.Scanner;
import java.io.*;

This is a stopwatch program. Somehow, the run method in the displayUpdater does not get called. Overall, the program should have a start button and when the user clicks start, the button changes into a timer. My timer doesn't count here because the run method is not called.

I am trying to compile multiple jar files into one jar file from inside a java program. I know how to do this with shell scripts but I would rather have a universal application than one that will only run on Mac, Windows, or Linux. This is my current compiler code:
if(System.getProperty() == "Mac OS X"){
Runtime.getRuntime().exec("javac -classpath jar1.jar; jar2.jar");
}
I would then continue this on for Linux and Windows, but this limits my application.
Here are the errors I am getting:
SlotMachine.java:21: error: illegal start of expression
public static void getNums(int [] slots)
^
SlotMachine.java:21: error: illegal start of expression
public static void getNums(int [] slots)

i keep fixing small things and cannot get it to compile. Below is the original code,
import java.util.Scanner;
import java.util.Random;
public class SlotMachine
{
public static void main (String args[]) {
int userMoney;
Scanner input = new Scanner(System.in);
System.out.print("How much money to start with?

The first 4 class below are the main classes while the last class is the testing class. I got it all to compile but for whatever reason there are several runtime errors. I have spent hours trying to figure out what they are, but I was only able to eliminate a few.

I have a program that runs in the terminal (I use Ubuntu). It asks the user for a String, does something with it, and terminates.It works in the NetBeans terminal, but not outside of it. Specifically, regardless of what I input, it doesn't continue with the program. I enter something, press enter and it just goes to the next line in the terminal.
Java Code:
Scanner scan=new Scanner(System.in);
System.out.println("Enter the music directory:");
String path=scan.nextLine(); mh_sh_highlight_all('java');
how do I pass in arguments when I run the program (still in Linux)? Is there a way to check if the program was launched from the terminal or not?
Netbeans do not detect any syntax errors, but I when I check the build it retuned areas they were a few; It's a simple program name 5 people, gade them then do final calulatoins it's called "grade tool.
heres the code
package gradingapplication;
import java.util.Scanner;
public class GradingApplication {
public static double score(double score){
if(score >= 90){
System.out.println("A");
[code]...
~Problems~
1. It has no gui, I don't know java fx, is java groove used? awt is useful for creating spam bots in robot class, I know it's not very useful but it's so much fun.
2. the sections where I use the scanner.
[ATTACH=CONFIG]27j.jpg49[/ATTACH]Hello,
I'm having the hardest time getting a program to compile. I'm beginning to think I've downloaded the incorrect version of turtle graphics. This symbol looks foreign and I'm unsure how to find a solution. I have fixed some of the errors since this last picture but I will write out my code. The program takes a photo and converts to gray scale then to sepia

import images.Pixel;
import java.util.Scanner;

A friend and I are working on a project in which we must test "super anagrams" (anagrams in which all characters in the first string are found in the second). We have a driver and definitions class pasted below:
Definition
class SuperAnagram{
String left = new String("");
String right = new String("");
[code]....
In the driver class, we get "cannot find symbol" errors at the beginning of cleanStrings and isSuper, both inside and outside of the if statement.
I am trying to run my program through netbeans and I get a message:
...build-impl.xml:1048 the module has not been deployed.
see the server log for details.
The corresponding line in the xml document is:
<nbdeploy clientUrlPart="${client.urlPart}" debugmode="false" forceRedeploy="${forceRedeploy}"/>
And in the server log there is a long list of comments, the first which looks to be of significance to this issue is:
WARNING [http-apr-8080-exec-57] org.apache.catalina.deploy.NamingResourcesImpl.cle anUp Failed to retrieve JNDI naming context for container [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/transBoard]] so no cleanup was performed for that container
javax.naming.NameNotFoundException: Name [comp/env] is not bound in this Context. Unable to find [comp].
There are others further down the list which might also be significant such as:

The corresponding line of code for the first warning that I listed is for the DataSource object and I wrote it as follows:
dataSource = (DataSource)
ic.lookup("java:/comp/env/jdbc/trans_board");
I'm pretty sure the issue has something to do with connecting to the database since it ran fine before I added the database related code.
It has no errors in it, but when it runs, it just doesn't show any output at all. Here's my code.

public class FuelGauge {
// Setting the gallons and the total amount of gallons
private int gallons;
final static int TotalGallons=15;

My Java program is failing to run in command prompt and no result is produced.I am currently using windows 8 and I have changed my Environmental variable to C:Windowssystem32;C:Program filesJavajdkin.
View Replies View RelatedI just created a Hello World program in Notepad, but command prompt still can't find it even when ran as administrator. I've even tried to use command line to run Hello World programs I've created with Eclipse but it still doesn't work. Here's proof I have JDK setup as PATH:
I've even tried having the JRE as path but that still doesn't solve my problem. I'm really trying to learn Java programming but this problem is holding me back.
I am struggling getting my java app to open a console window on either MacOS or windows and run a command. On windows I can get the cmd.exe program to open, but it won't execute the command. On MacOS, I cannot get it to even open the terminal.

I am reading the excellent book Algorithms. The author of this book is using his own libraries.
I have downloaded the libraries (it is a file called stdlib.jar) and I've store it in a directory called ~/Downloads(I am using a macbook pro).
Then I have created a project with IntelliJ Idea 14.1 using the default package (as it is the only way for a program to 'see' these libraries).
The program is running inside the ide, but because of the nature of this book, all the included code must be run from the command line.
The problem is that I cannot run for example the Average class from the command line because the system asks for the external library.
Specifically the error is :
I enter : java -cp . Average
and the Error I get is :
Exception in thread "main" java.lang.NoClassDefFoundError: StdIn
at Average.main(Average.java:11)
Caused by: java.lang.ClassNotFoundException: StdIn
at java.net.URLClassLoader$1.run(URLClassLoader.java:372)

The Average class is the following :
public class Average {

//Average the numbers on StdIn
double sum = 0.0;
int cnt = 0;

Write a java program to accept a string, float and an integer as command line arguments. String value should be displayed. Also the program should display the maximum value of two numbers. Use Integer.parseInt() and Float.parseFloat()
