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.
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 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"

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...
While doing trial and error got caught in the below scenario.
public class Crypt { public static void main (String args[]) { /*all I want is calculate a binary number (ex -: 22 , 34) using decimal base (10n). *So, I have to convert 2 p into 10n form so I have to find n in terms of p . We have x as the input. * The formula works as below. *2p =10n *p ln (2) =n ln (10) *n = p [ln(2) / ln(10)] *2 p = 10 p [ln(2) / ln(10)]
I am having a problem with the JavaFX MediaPlayer playing videos with resolutions greater than 1920x1080px. For testing purpose I downloaded the example from [URL] ... and added the following error-handling:
The video is encoded with h264 and aac (for audio) and is having a resolution of 1920x1168px. The error occurs with each video with a resolution greater than 1920x1080px. Vidoes with a resolution of 1920x1080px or smalle are working fine. The playback of all videos is working with VLC-Player. I tried Java 7_51 and Java 8_5.
I have uninstalled JAVA because I needed to download the 64-bit version but no matter WHAT I do I still get the same installation error message "keyset as registered in invalid" and I was downloading it from [URL] .... I will do whatever it takes to fix this!

Questions:
1. Describe what the code displays. A error message would be shown when the use has selected an insufficient number of options.
2. Describe when an event handler (included in the code) gets executed? The event handler gets executed every time a user selects an option(???)
3. Explain a feature of what is displayed
4. Explain the meaning of all of the parameters in the central, complicated call of the code.
5. Describe how the code handles two possible situations.When the user has selected a sufficient number of options (no less than or equal to 0), then no error message would be shown. On the other hand, an error message will be shown when the user has not selected a sufficient number of options (0). (???)
Reading a sequential flat file (which is working) but now I need to add code to update the status flag (setting it to ‘Y’ position(7,1)) before I close the file and not sure how without defining the fields.
I'm trying to make it to where each button is supposed to display the country's flag and a description. As of right now, I've hit a roadblock and haven't been able to get past it. As of right now, without the errors in the setDisplay method where setTitle and the other two are undefined for that type, I get each country's name listed as a radio button.
However, I haven't been able to get anything else to display.

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.
