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

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.

Tomcat suddenly cannot run on Mac as the first time when it was installed, it ran properly. Before the problem happens, there was a small upgrade of Java from 1.8.x to 1.8.x. Not sure if it causes the problem.
Have tried several solutions with searching "catalina.out: Permission denied" but the problem still exists.
catalina.out: Permission denied
path
The user trying to start the tomcat does not have the rights to write the file catalina.out in logs directory of your tomcat installation.
Most likely last time you have started the tomcat as another user.
Simplest solution is to remove the existing catalina.out, e.g. using sudo rm logs/catalina.out

I'm trying to create an android application to scan other applications for viruses, or malicious code etc. But to begin with, I'm trying to figure out how existing anti-virus scanning systems operate.
I don't think its rooting, because there are a lot of anti viruses that don't need rooting. If I have to guess, I would say it scans the files for signature. And they access the files similar to how file explorers work. Someone more knowledgeable can correct me.

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.
