How java runs in command prompt and why java runs on it

how java runs in command prompt and why java runs on it

command prompt was used before the development of IDEs like RAD,eclipse etc.
its still used for better understanding of the compilation and errors.
type the java file and save the file(source file) in the bin folder of ur jdk environment with extension .java. the source file must be the one that has the main method declared.
in the cmd prompt screen , set the path of bin folder.
eg:C:/program files/jdk(some version)/bin/...
for compilation,type:
javac (source file_name).java and press enter
for running the file:
java source file_name

Thank in advance!

Write your own Thread, to do this:
public class KeyThread extends Thread {
   public void run {
      while(true) {
         int i = System.in.read();
         if(i == 123) {
            break; // to stop the thread
// in your main:
Thread keyThread = new KeyThread();
keyThread.start(); // calls run() of the thread

Running eclipse java project on command prompt

Hi all,
I have one simple java project and that is very well running in eclipse. I have added some external JARs to that project. It performs this job- it creates connection to server, and listens to the signals from server.
My question is - how do I run that java project on command prompt?*
I want to run that using ANT or simply I want to make a JAR file so I can execute JAR on command prompt. I created JAR, but it doesn't contain external jar which I added to the project. So I was not able to run that project.
Can you please tell me any of the method - using ANT or by making JAR?
Also can you be little bit more explanatory in reply?
Thanks

I want to make a JAR file so I can execute JAR on command prompt.This is very likely a good way to proceed. It is explained in great detail in Sun's Tutorial in the section on [Packaging Programs in JAR Files|http://java.sun.com/docs/books/tutorial/deployment/jar/index.html].
I created JAR, but it doesn't contain external jar which I added to the project. So I was not able to run that project.Yes - the jar file you create has to know about the classes and other resources in that external jar. Otherwise, at runtime, the program will not be able to get at the stuff it needs. Usually you don't include that other jar (or its contents) in the jar file you are creating. Instead you provide your jar file with a manifest that describes the other jar's location. Details are also in the tutorial.
One thing to note is that Sun's tutorial provides a lot of explanatory, conceptual, material. To that end it keeps the context simple and transparent by describing the steps as they would be carried out by someone working at the command line. The Eclipse documentation and forums might provide a more click-this-drag-that "explanation". If you do follow the method in the Tutorial and get stuck, post a description of the actual commands you used and their outcome.

SignTool.exe verify /pa returns exit code 1 from the code but works fine while running from command prompt

Hi,
I am using SignTool.exe from a new Process() to verify a codesigned assembly and it returns the exit code 1 whereas it returns exit code 0 while i run the same from Visual Studio Command prompt. Please let me know your thoughts...
Here is my code snippet from VS2012 ultimate on Win7 PC.
p = new Process();
p.StartInfo.FileName = "C:\\Program Files (x86)\\Microsoft SDKs\\Windows\\v7.0A\\Bin\\SignTool.exe";
string args = @"verify";
p.StartInfo.Arguments = args + " "+ "/pa " + "/v "+ name;
p.Start();
p.WaitForExit();
pexitcode = p.ExitCode;
//name = "C:\\Users\\v-maparn\\Documents\\Visual Studio 2012\\Projects\\CodesignVerification\\CodesignVerification\\bin\\Release\\Microsoft.IT.Core.dll"
Thanks,

Hi Amy,
Thanks for your reply. I am receiving the exit code 1 by the Process even though the SignTool is able to successfully verify the assembly. I ran the below command from command prompt and received no errors or warnings. I assume the exit code should be 0.
I have also verified that this assembly has digital signature embedded as you can see from the output.
output:

Using Java in windows command prompt

Hi,
I don't know if I have been searching correctly, but I haven't found a solution to my problem through common search engines.
I'm programming in java using vim (accessed through windows command prompt), and I've created classes, everything compiles fine.
However, I wanted to test my classes my creating instances of them (i.e. objects) through the same windows command line (command prompt). I know you can achieve this by using interaction panes through third party programs such as Dr.Java and eclipse, but I was wondering if this can be done using the command line.
Thanks
Jaime

Thanks Paulcw for your quick reply! :D
I'm guessing I didn't word my question properly.
Neither of my classes have a main method in them, so when I am trying to create instances (objects) of them, I would like to as if my command line was the main.
For example:
Class1 c = new Class1(parameters);
c.moveRight();
etc.
I'd like to be able to use my classes methods from the command line, I think what I'm looking for is a batch, but I'm not sure.
Thanks again,
Jaime

I'm trying to update my iphone 3GS to the 4.3.4 version and I am getting the error message "This version of itunes (version 9.1.1) is the current version. How do I update my PHONE and why is an itunes update being confused for my iphone?

You need iTunes 10.0 or greater to update your phone...iTunes isn't confused at all. If you're on a Mac, you'll need OS X 10.5.8 or greater to update iTunes to 10.0 or greater.

I installed iOS 7 and it deleted some of my contacts, as expected, so I just resaved them all. There's one particular number that will save but in my messages, it shows up as the number instead of the name saved. How do I fix it? And why is it doing that?

I had this problem too, I fixed it by going to my settings and under general at the bottom there is a reset option, go there. One of the options should be reset network settings, select that one. I’m not sure why it happens but that worked for me; hope you have the same luck!
