When I enter java -version in my console, I get java version jdk1.7.0_11 and running javac -version shows jdk1.7.0_11.
However, it seems that matlab could not find javac, thus, I am not able to compile my .m code into a .jar file. When I tried to compile .m code I got the following:
Java Code:
Error: An error occurred while shelling out to javac (error code = -1).
Unable to build executable.
Executing command: ""C:Program FilesJavajdk1.7.0_11binjavac" mh_sh_highlight_all('java');
This is the directory of my java bin folder and javac.exe exists : CProgram FilesJavajdk1.7.0_11binjavac.exe? What should I check in order to correctly link Matlab to Java?
I've been trying to finish this blackjack program I have been making for my programming class, however, there are a few bugs I can't seem to iron out. It's a pretty short program, it's just that I'm an idiot and can't figure basic stuff like this out. Specifically, when I try and run it, I get this error:
Error occurred during initialization of VM java.lang.OutOfMemoryError: unable to create new native thread
So today i was trying to compile a simple script that used to work before on Sublime Text 2, an i got the following error;
javac: invalid flag: Usage: javac <options> <source files> use -help for a list of possible options
I already know the script works because i didn't change anything since the last time it work, but anyways just in case i tried running a HelloWorld program just to check it out and i got the same error. The i stop trying to compiling the HelloWorld on Sublime so I went to Terminal and i got the same exact error.

I've installed the Java JDK onto my Windows 8 laptop and the first thing I need to do is run the compiler from the Command Prompt. The first prompt I enter is C:java -version. This worked fine, however when I try to enter the next prompt C:javac -version, I am getting the following screen and messages:
Microsoft Windows [Version 6.3.9600] (c) 2013 Microsoft Corporation. All rights reserved.
C:UsersMary>java -version java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26) Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
C:UsersMary>javac -version 'javac' is not recognized as an internal or external command,
operable program or batch file.
I have entered the path into the environment variables area within my control panel. Not too sure why the first prompt works, but the second doesn't...
The problem is, the values are completely different than they are saved in MATLAB, and probably I need to shift the values after transforming them into byte arrays.My Java code which reads values of floating numbers from a MATLAB bin file as follows:
import java.io.*; import java.io.File; import javax.imageio.ImageIO; import java.nio.ByteBuffer; // may be useful? public class floatingNumberMatrixReader {
I first time tried Java web service sample example using eclipse with axis2. First i wrote the provider class. Then by clicking create Web Service from the provider class It will show the following error "IWAB0014E Unexpected exception occurred." I have attached the screenshot for reference.
I'm trying to use the javac -sourcepath option to compile superclasses without explicitly naming them. I've been looking at examples, other posts, and trying variations for a while without success.
I have:
package ActorBase0.classes; public class Bridge extends Place { ......
Place is also in package ActorBase0.classes and the source files are in the same directory .... ActorBase0sources
I have just tried to learn java this week [COLOR="#000000"]and I am being held back by this once installed java jdk I nav to the java file and the bin file and then the javac file to find that the below tab does not exist
A new window should pop up giving the properties of the javac, there should be an attribute called Location..I can see the location option in my documents but in no other folder
It should be possible to let the javac create a subdirectory according to the file's package statement. So I have tried: Java Code: javac -d C: estMyApp.java mh_sh_highlight_all('java');
That always gives me the message that javac could not create the directory.
For my jsp file, the code editor shows no error, but the projects window shows an error. I built my project again, cleaned the project, restart eclipse twice and summoned cthulhu. But my project still shows an error. How do I find the cause.

So I am working on a school project and I have 2 classes, class FakeGravity contains all the properites and class BouncyBall is my driver class. For some reason when I try writing
FakeGravity gravity = new FakeGravity( );
I get an error. I am attaching an image of the error, and also attaching the program just in case you need more information. Also I was using blueJ to write the program
