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

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 {
[Code].....
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 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)
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?
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) .....
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.
Now everything works in Netbeans but running it from the command line, i get an error message ".java uses unchecked and unsafe operations".I have added a bit more code to the code above
for (int i = 0; i < args.length; i++) { System.out.println("args[" + i + "]: " + args[i]); }
Just not sure how to run it from the command line,
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?
I'm facing another problem with the HFJ code which i edited some what (as given HFJ) to make it work through command line..BeatBox using command line. Getting compiled but no sound coming..
package com.BB.getPlayer; import javax.sound.midi.*; public class MiniMusicAppCmd { public static void main(String[] args) { // TODO Auto-generated method stub
I am trying to interact with the command line prompt and script the responses for some config. When asked if user wishes to continue I would like respond yes or no, however I would like this response to be automated without any user interaction. I am able to launch the .exe file however when the command prompt is launched I cannot get any further responses to it.
p Java Code: ublic static void runConfigure(String[] refBox1,String outDir2) throws IOException{ String s = null; try {
What I'm supposed to do is use the time class and take the command line arguments and print them as the start and end times and then calculate the elapsed time between the two. My issue (hopefully my only as I have been working on this all day now) is that I cannot call the command line arguments using LocalTime. Below is what I have so far.
public class Clock { private LocalTime startTime; private LocalTime stopTime; //default constructor-initialize startTime to current time public Clock(){ this.startTime=LocalTime.now();
I am trying to make a method that takes in a cmd command (nslookup, systeminfo, etc), and outputs the response to a text file. I have tried a dozen different ways with no success. below is my most current failure. It succeeds when i run it, but nothing shows up in the text file.
public static void runSystemCommand(String command) { command = "ping 192.168.1.3"; try{ Process proc = Runtime.getRuntime().exec(command); InputStream in = new BufferedInputStream(proc.getInputStream()); OutputStream out = new BufferedOutputStream(new FileOutputStream("C:NetPanelDataping.txt"));
I'm having trouble with how to read a text file into my program so the words can be sorted alphabetically. Should I use something like a FileReader?
An example of what I'm trying to do is a .txt file that holds the statement "java is a simple object oriented and distributed and interpreted and robust and secure and dynamic."
The output should organize the words like so: and and and and distributed dynamic interpreted is java object oriented robust secure simple
Here's what I have:
public static void main(String[] args) { if (args.length != 1) { System.out.println("Usage: java AscendingAlphabet"
[Code].....
I can never get it to read the file correctly, it just prints the "usage: java..." statement.
I'm writing a Java program to get the gpa of a student as a command line argument. Then display the class of the degree according to some criteria. Here is my code. But it says "ArrayIndexOutOfBoundsException :0". How can I fix this?
public class Stgpa { public static void main(String[] args) { double gpa= Double.parseDouble(args[0]); if(gpa>=3.6) System.out.println("Class of the degree is: First Class Hons"); else if(3.6>gpa && gpa>=3.4)
I'm learning about the printf command, and when I have it, it is not letting me ad an input. Here is my quick little program:
import java.util.Scanner; public class TestingPrintF { public static void main(String[] args) { // Create a Scanner Scanner input = new Scanner(System.in);
[Code] ....
The first section works good, but when i move down to the second part it just automatically finishes without letting me enter a phrase.
How would I randomly assign colors and a with a name? Some functionality may require command-line arguments but I am a bit confused on how to structure this. Also, these names must appear on a color coded on a gui
