When I am trying to run an applet in command prompt I am getting an error message saying: System cannot find the file specified.
Initially I compiled my applet using javac BubbleSort1.java it works fine But when I tried running this using: appletviewer BubbleSort1.html I m getting the above error. Anyhow, both the html file n the java file are in same folder in C drive. (windows 7) .....
My PC runs on Windows XP. When I try to run a java program (written using NetBeans) from the command prompt, the program opens in NotePad but does not run.This is what I have been typing at the command prompt:
C:javahellosrchelloHello.java
The above is the correct path to the Java file on my PC.how to run the program from the command prompt or perhaps link me to a tutorial that explains it?
I downloaded this code from Head First Java. But when I tried running it on Eclipse, it gives this error message.
import javax.sound.midi.*; public class MiniMiniMusicApp { // this is the first one public static void main(String[] args) { MiniMiniMusicApp mini = new MiniMiniMusicApp(); mini.play();
[code]....
and this was the error message: Jan 02, 2015 8:10:36 PM java.util.prefs.WindowsPreferences <init>Could not open/create prefs root node Software Java SoftPrefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.
I'm suddenly having trouble running classes from the command line. Previously, things were working. I cant imagine I'm doing anything differently. The sample code is below:
Code:
class HelloWorldTester{ public static void main(String[] args){ System.out.println("Hello World"); } }
Terminal output:
C:UsersmattmanDropboxProgrammingJava>javac helloWorldTest.java C:UsersmattmanDropboxProgrammingJava>java HelloWorldTester.class Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorldTester/clas s Caused by: java.lang.ClassNotFoundException: HelloWorldTester.class at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: HelloWorldTester.class. Program will exit.
I am just learning Java and I am have a problem running programs at the command line. I have the following code:
package java_help; import java.io.IOException; class help {

I can run this program in net beans were I originally wrote the program and it runs fine there. I also compile the program at the command line using javac but when I go to run this program I get a error message that it cant find main.
I've Installed oracle JDK version 1.8 on a debian machine that already has openjdk 1.6.i've set the path variable in etc/login.defs and java_home variable In etc/environment. When I echo $JAVA_HOME it points to the oracle version correctly and when I run javac It uses the oracle 1.8 version. The problem is when I run the java command , It runs the openjdk 1.6 version and I'm not sure why.If I type java -version It shows the openjdk version.
I am operating java from the command line (using Terminal on Mac OSX 10.9.5).The current directory within Terminal is called "orange" and the following sourcecode file is in the orange directory :
Test1.java package orange; public class Test1 { public static void main(String[] args) { System.out.println("Test1 works"); } }
This complies to Test1.class (visible in the orange directory) but when I try to run it in Terminal (simply using "java Test1" from within the orange directory). I get the following error message (which I don't get if I simply comment out the line //package orange;)
Exception in thread "main" java.lang.NoClassDefFoundError: Test1 (wrong name: orange/Test1) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449)
error: File .ServiceServerImpl.class does not contain type ServiceServerImpl as expected, but type serviceserver.ServiceServerImpl. Please remove the file, or make sure it appears in the correct subdirectory of the class path. error: Class ServiceServerImpl not found. 2 errors "
Here is the source code of the class file. Using Windows 8. I copied the .class file to the rmic.exe 's location later. didn't work either way. It is in a package called "serviceserver"
package serviceserver; import java.rmi.*; import java.rmi.server.*; import java.util.*; public class ServiceServerImpl extends UnicastRemoteObject implements ServiceServer { HashMap serviceList;
When i run a applet file in browser(IE, Chrome, Firefox) it gives a error of security risk and block the application from running. All browser are giving same error. Programme is running correctly in Myeclipse
I keep getting the error Admit.java:10 cannot find symbol
import java.util.*; public class Admit { public static void main(String[] args) { sayIntro(); Scanner console = new Scanner(System.in); System.out.println("Information for applicant #1:"); getScore(console); getGPA(console);
[Code] ....
The compiler then reads:
Admit.java:10: error: cannot find symbol score1(ACTScore, SATScore, GPAScore); ^ symbol: variable ACTScore location: class Admit Admit.java:10: error: cannot find symbol
When I try to run my runnable jar file, it wont do anything. And when I try to run it from the console, it says
"java.lang.UnsatisfiedLinkError: no LWJGL in java.library.path..."
How do I fix this?
I've specified the path by properties > Libraries > lwjgl.jar > Native Library Location > .... And I chose the right paths. But I still get that java.lang.UnsatisfiedLinkError.
It says I'm getting an error on line 34 which is:
appgc = new AppGameContainer(new Game(gamename));
My whole main class is:

I am trying to execute a program from the command prompt. I type java -jar zuul.jar (zuul is the name of my project) and I get a message that java is not recognized as an internal or external command. What do I do wrong?
I made the XML file (web.xml) in C:Program FilesApache-Tomcat-7apache-tomcat-7.0.53webappsDEMOWEB-INF folder. In command prompt I went to the classes folder
Im following a simple set of code and can not get the correct output, in chapter 1 (Intro to Java).Im stuck on getting a set of code to run completely through command prompt. I installed.JDK and textpad4, type the code, save it, direct towards it in cmd prompt but javac wont work. Here's the code I put in textpad;
public class Test { public static void main(string[] args) Ststem.out.println("3.5 * 4 / 2 - 2.5 is ") System.out.println(3.5 * 4 / 2 - 2.5);
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.
I was wondering if their is an easily explainable way to convert a jar for a text-based game that runs off the command prompt into a executable. I would guess there probably is not and the game would have to run off of completely different commands, but I thought it couldn't hurt to ask.
I 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.
This is a program that prompts a menu using the do-while iteration. If user input is not valid, the menu should be reprompted once. But when I run the code and enter an invalid value, the menu is prompted 3 times.
class Menu { public static void main(String args[]) throws java.io.IOException { char choice; do {
I am making a ui in which i have a JTextfield and a JButton(run). I am reading values to JTextField from text file and on pressing Jbutton a Batch file runs. Now when i press the Jbutton the batch file runs showing number running, in place of number running, i want to display the JTextfield value. So i want in place of number running it should display JTextfield value running. How can i achieve it.
