Signal handling is a programming concept that allows programs to talk to each other via 'signals'. A user can also issue signals to a program at will using the 'kill' command.
For example,
kill -15 <command> tells the command to terminate
kill -9 <command> tells the command to terminate forcibly
kill -USR1 <command> tells the command to do whatever it was programmed to do when it received the USR1 signal.
It is working, so you may have made an error, or your JRE/JDK version is too old, or whatever else.
A signal is a command sent by the operating system or by the user, to a program or process, forcing it to do something. The "kill signal" forces a program to immediately "close" (terminate) regardless of what it is doing. You should not use the "kill signal" unless the program has a problem or cannot end or close properly, because you will lose whatever it is working on.
Linux Internals is a book about how Linux works.
The 'kill' command sends a signal to a given process. By default without any options it will send the TERM (terminate) signal. Other options may include the KILL signal which forcbly terminates a process without waiting. As far as USR1 and USR2 signals it depends on the kind of application that is in said process.
Linux World is the Linux Development & Training Center
The courses available for Linux include Linux server, Linux desktop, bash shell, and many others.
One can obtain the latest Linux news on websites such as CRN, Linux Today or Distro Watch. One can also find news about Linux on Arch Linux and Linux Journal.

Linux Flavour
No, it is unix-based but Linux is a kernel not an operating system.Ubuntu,Linux Mint,Debian,and puppy Linux,ect. are OS's that use the Linux kernel.
Linux does not have a "manufacturer." Linux development is guided by the Linux Foundation and Linus Torvalds, with contributions from thousands of companies and individuals.
No, but Linux is based on Unix since Linux is a Unix clone.
