There is a small battery on the motherboard of your computer that provides energy to keep the clock running.

The rest of the computer receives no power when the computer is off, and it's not possible to run programs on a computer that's switched off.

When this happens, as said above, only a slight amount of power is running through the system. No power from the power supply is running to the cpu, hard-disk, memory, or any other entity.

What you can do is write a server-client application, and keep the server running 24/7. But this isn't a feasible option for most apps.

if it is possible to open the cdrom without pushing the button than it is also possible to on the cpu without pushing the button because restart is also work without the pushing so how I can do this

Vivek,

This is the exact same question you asked here https://coderanch.com/t/487562/Java-General/java/Boot-java. There already are many replies to your thread there.
