At school when I try to debug my work, a little window pops up that says "Could not connect to a free debugger socket"
this does not happen to my friends when they try debugging their programs, only mine
this also does not happen at home, so if I want to debug, I either give my friends the code or I bring it home on a USB.
this happens in both Eclipse and JGrasp for me.
school computers are running Windows 7
If you know how to fix it, please help me!
On jGRASP under "Settings" / "Java Debug Settings", you can change the preferred connector to "Shared Memory". You can probably similarly choose the connector type for Eclipse. That should allow you to debug, but I have no idea what the root problem is.

On my Windows 7 machine the Java update consistently fails with this error message.This seems to a common problem, does anyone have an insight into what's going wrong, and is there a fix for it other than either disabling the update check (seems a bad idea from a security point of view) or waiting for the nag message and then manually installing the new version (annoying and stupid from a usability point of view).
I downloaded offline and online installers from the official java website, but they just don't run

This is my issue when I try to Login on Emulator!
How do I resolve this?
Android Studio, at least in my experience, has been extremely buggy. Try the following steps:
Restart the emulator
Wipe data from the device (using device manager)
Use another emulator (create another device using device manager)
Restart Android Studio
Restart your PC
If none of the above work, create a new project and copy paste your code onto that project. I know it seems silly but it has actually worked for me!
Hope this helps.

I remember having to deal with this error when I was working with Java web services, my problem was I didn't stop the service completely when I needed to reload it and when I tried to start a new instance it couldn't (giving me this error) because I had it already running. My "fix", for what I remember, was just going in the processes and stopping it manually.

I know a lot of similar questions have been asked, but I didn't find what I wanted in any of the questions. I am a beginner, don't know much about anything.
double x = Math.random();
System.out.println(x);
When I press my Ctrl key and press 'Math' keyword it shows source not found, even when I try to open the declaration and implementation of Random, it shows the same error.

In Eclipse, go to window->preferences->java->installed JRE's. Then double click on the one you are using and navigate to the source location and link to the src.zip that should come with your JDK. You should see a window that looks something like the following: (Note that this is where you would configure the source location and the JavaDoc for the API).

I wrote a java application whit my windows Pc. When i try the same application on a MAC Pc i had this error: "can't be opened because it is from an unidentified developer".
I tried looking for this problem on Google and I read that this option can be
disable, but i dont wanna do it. How can i fix this problem? Should I buy a licence or somethink like that?
Based on this post on the Apple Support forum, it appears that you must enroll in the Apple Developer Program to become an identified developer. This will get you a Developer ID certificate from Apple that will cause your app to be recognized by Gatekeeper as having come from an identified developer.

I posted a questions a couple of days ago about eclipse notifying me of an error I didn't have.
An error appears under my project name but no error exists?
I fixed that error but now I face another problem. Under my project name, a little yellow warning sign appears. My program runs fine though. Can someone explain to me what it means or how to get rid of it?
Click Window > Show View > Problems to open the Problem View. This should list any warnings/errors showing up in Package Manager.
