Create a Java file runtime and Execute to get result

Hi,
Is this possible to generate a Java Class run time and execute it to get result..if yes how...any example or site reference..
Thanks

Yes: http://www.java2s.com/Code/Java/JDK-6/CompilingfromMemory.htm
It would be better if you tell us what the problem is that you want to solve.
The above may not be optimal, as it requires you provide your users with a part of the JDK (not JRE!): tools.jar, placed correctly in a jre directory, if I remember well.

It sounds like you might be able to write a .bat script to run the application, create a desktop icon for that and set its properties so it runs in the background.

Create a Java File

Hello,
I have some java script that I embed into my html, is it possible to create a java script file with this script? This way I only have ot update the script.
I have dreamweaver and I tried to create a java file using that but when I choose to insert an applet and choose the file I create nothing happens.
Any help would be appreciated.
Thanks,

Use a JS (Javascript ) file and embed it into the HTML. Use relative path to refer the JS
The script to include the JS file in a HTML is :
<script language="JavaScript" src="javascriptfilename.js"></script>
let me know if this helped you.

Why java file name and class name are equal

could u explain why java file name and class name are equal in java

The relevant section of the JLS (?7.6):
When packages are stored in a file system (?7.2.1), the host system may choose to enforce the restriction that it is a compile-time error if a type is not found in a file under a name composed of the type name plus an extension (such as .java or .jav) if either of the following is true:
* The type is referred to by code in other compilation units of the package in which the type is declared.
* The type is declared public (and therefore is potentially accessible from code in other packages).
This restriction implies that there must be at most one such type per compilation unit. This restriction makes it easy for a compiler for the Java programming language or an implementation of the Java virtual machine to find a named class within a package; for example, the source code for a public type wet.sprocket.Toad would be found in a file Toad.java in the directory wet/sprocket, and the corresponding object code would be found in the file Toad.class in the same directory.
When packages are stored in a database (?7.2.2), the host system must not impose such restrictions. In practice, many programmers choose to put each class or interface type in its own compilation unit, whether or not it is public or is referred to by code in other compilation units.

Since I downloaded Apple's latest operating system, whenever I try to open Illustrator I get a message that I need to install legacy Java SE6 runtime and to click "more info" to do this. When I click "more info" I get a blank window. What should I do

Since I downloaded Apple's latest operating system, whenever I try to open Illustrator I get a message that I need to install legacy Java SE6 runtime and to click "more info" to do this. When I click "more info" I get a blank window. What should I do

Hi,
I had the same problem after upgrading to Yosemite. Illustrator CS6 wouldn't open. I got a message saying I should 'install legacy Java SE6 runtime'.
The link didn't work - it lead to a blank page.
So I downloaded Java8 (latest version) from Oracle but didn't install it. Something told me this was not the right way to go (the problem was with Java SE6, not 8). I then called Apple (in the Netherlands, were I live) for help. I got none. The best they could do was blaming Adobe for the problem or me, for not having the latest Adobe CC app. Rubbish.
And then, magic. I tried to open Illustrator again, got the pop up message but this time the link worked. It took me to an official Apple page, with a link to download Java for OS X 2014-001. The problem is now solved.
If curious, this is the explanation Apple gives for the problem:
'Java for OS X 2014-001 includes installation improvements, and supersedes all previous versions of Java for OS X. This package installs the same version of Java 6 included in Java for OS X 2013-005. On systems that have not already installed Java for OS X 2012-006 or later, this update disables the Java SE 6 applet plug-in. To use applets on a web page, click on the region labeled 'missing plug-in' to download the latest version of the Java applet plug-in from Oracle.'

How to Create Dynamic button at runtime and save it by using c#?

Hi All,
Can someone please provide me code to create button dynamically at runtime and save it permanently?
Your quick help is appreciable.
regards,
Sourabh

You cant add controls to the visual tree a runtime which persist beyond the lifetime of the application. You will have to persist an indicator to your program which tells it to add the control. Adding a control is as simple as initializing
it and adding it to a parent already on the tree. Controls can be created programmatically or using the XamlReader.Load static method. You can find XamReader.Load in Windows.UI.Xaml.Markup in windows 8.1, Windows 8.1/Windows Phone unified
projects. For old windows phone ad just Silverlight I believe it is in System.Windows.Markup.
Hope this helps.

How to create a .java file through a j2me program?

I am trying to develop a small application in j2me which needs dynamic creation of a .class file. For this purpose I tried to create .java file through my j2me code, but i could not do that..I want to know whether a java file can be created on a mobile phone or not..
I would be grateful to you on your help in this regard..

...develop a program xyz.java using j2me which performs the following functionalities:
1.create a file called abc.java
2.extract its class file...For +1+ ie to create a file (any file, no matter java or not) from j2me, device need to support File Connection specified in [jsr 75|http://www.jcp.org/en/jsr/detail?id=75]. If you're interested, learn the jsr API on how to create and manage needed file.
For +2+ described as extract its class file one needs to have java compiler (javac) on device. *) If you're interested, ask for more details at [Java Compiler forum|http://forums.sun.com/forum.jspa?forumID=7]. Also, if the class file is for CLDC then javac needs to support "JDK 1.3-compliant" compilation. To create CLDC classes on device, one also needs to have a preverifier tool. Check this at Java Compiler forum if needed.
Good luck - I think you'll need a lot of it...
*) javac on device -- it should not only be present but also provide a j2me API allowing to invoke it for particular java file with needed options. Same applies to preverifier tool.

Creating any .java file

can it be possible to create .java file from .class file? if yes then how? here basically i want to get source code through .class file , is it possible to get?

Hi,
It depends. Well, if you are going to use only a web application,
then creating an .war will help. If you are using EJB's then .ear file
is suitable. In your case, I believe .war could be sufficient provided
the application is not too complicated. Hope this helps.

How to create a .java file with multiple classes

I have all the below classes declared in a file say ABC.java under
a common package called somepackage
Abstract class A
Void abstract metod1();
Void metod2();
Class B
void method3();
Void method4();
Class C
void method1();
Void method2();
In Client.Java
On compiling the Client.Java I get errors
Import somepackag.*;
Class Samp extents A
void Method1()
Public class Client
A a1 =new Samp(); //error undeclared class A
B b1 = new B1();//error undeclared class B
C c1 = new C1();//error undeclared class C
is it possible to have all the class declared in one file ( i dont need mutiple classes, as this file will be autogenerated , i need all classes in one file) and use the classes inside this in the some client app
regards

As long as you have only one public class and your .java file is named after it you shouldn't have any problem.I did exactly that, but still i get the same error "Cannot find symbol"
i have used the import command on top as import somepackage.*;

Image Policy when I create a PDF file: warn and continue doesn't work

Hi!
I need to create a PDF file with lots of images, and I need to know if any of that images is in low resolution (<300 ppi). I have tried to use the image policy in the PDF settings but it doesn't work, because if I choose "Warn and continue" (if the resolution of any image is <300 ppi, warn and continue) the program creates the PDF file but don't warm me and I don't see any message... and I'm sure that there are bad images because I have made a check test with 72ppi images.
Thank you very much for your attention,
best regards!!
(Sorry if my English is not as good as it would be)

Thank you very much Bernd Alheit, that's perfect for my job!
Thank you!

Thanks for this. Alas, I do not have the source code used to generate the jar file, and I have no means of getting it. I imagine, therefore, that I will not be able to update the manifest file.The manifest file is just a simple text file.
You can get at it by unpacking/repacking the jar file with the jar utility (tar like syntax).
... I assume that classpath is rather like the unix path.It specifies a list of jar files and directories containing java class files (and more).
Is there anything that defines the classpath for each login session and, if so, how do I add to it?As the link I posted says;
you can set a CLASSPATH env.var.
