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 am a novice to coding and very new to Java. It appears that I am having a similar problem as the user above "Scott Allen". With a few exceptions. My issue is that when I run the command "javac" from the command prompt I am receiving the same error:- "javac is not recognized as an internal or external command, operable program or batch file"
After reading the comments from above I have configured my System Variables "Path" and "JAVA_HOME" to match the following:
JAVA_HOME: C:Program FilesJavajdk1.6.0_21in
Path: %JAVA_HOME%in; [First Variable]
There is no "Path" User variable on my computer, although there is a "TEMP" and "TMP" in the User Environment variables.
Currently I have the following Java related software installed:
- C:Program FilesJavajre6
- C:Program FilesJavajdk1.6.0_21
- C:Program FilesSunJavaDB
- C:Program FilesEclipse-jee-galileo-3.5.2
I have confirmed the "javac.exe" is located within the in directory of Javajdk.1.6.0_21..When I send "Java -version" to the command prompt the following is returned: java version "1.6.0_26"..Immediately I noticed that the version is wrong, but don't know why or what to do. Below is the output from the command "Java" using the command prompt.
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-client to select the "client" VM
-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is client.

I am trying to run tshark command using runtime environment in java on ubuntu . My code is as follows :-
try {
String destip = map1.get((String) innObj.get("value"));
Runtime run = Runtime.getRuntime();
String tshk = "/usr/bin/tshark -r /home/pratibha/Desktop/vox.pcap -Y "ip.dst == "
+ destip
+ " && http" -T fields -e tcp.port -e col.Info";
Process pr = run.exec(tshk);
[code]....
map1 is hashmap which contains the destination ip adress.When i run the above code the exit code for process (pr) is 1 and hence the tshark command is not executing properly.

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)
[Code] ....
The Average class is the following :
public class Average {
public static void main(String[] args) {
//Average the numbers on StdIn
double sum = 0.0;
int cnt = 0;
[Code] .....
I have the program written correctly, but it won't execute.
public class Welcome {
public static void main(String[] args){
//Display message Welcome to Java! on the console
System.out.println("Welcome to Java");
}
}
I compiled the code as written below with "javac Welcome", and use the "Class" name "Welcome"
The file path is: C:Java Programs
Javac Welcome.java
Java Welcome
Below is the result of the above commands
javac Welcome

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.

3. I've made sure the PATH is set correctly in environment variables, with the Java path at the beginning of the path string).

Full question: Implement a program that reads in a Java source code file and checks to see if it has balanced {}brackets. Your program should use a stack, implemented as a linked list, to check the brackets.
NOTE: you can use a reference called top which points to the head of the list. Your program should run as a command line program and should take a filename as an argument and print one of BALANCED or NOT BALANCED.
For example: c:> java checkBalanced "myProgram.java" BALANCED

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?
