[Java] Make a musical note without using any external library

[Silicon Waffle]

Do you know how to make a musical note in Java without using any external library ?
In C# I can simply do this :

Console.Beep(50,1000); //play a sound at 50Herz of frequency within 1 second

The basic answer is:

java.awt.Toolkit.getDefaultToolkit().beep();

but to get frequency and duration you need to use more specialized code:

5 years of c# coding and I had no idea Console.Beep existed. Mind == Blown
Have actually wanted sound synthesizing code for awhile without using a library, thank you.

Isn't the system beep something special though? I seem to remember a desktop computer where system beep came from a special speaker, other than the speakers.

I programmed a real-time vocoder in Java once, it wasn't the best language for real time audio, but it did work. I'm pretty sure I just used the builtin:

If you're actually wanting to make the musical notes, the western temperment is called 12TET, you'll find the math here:

Isn't that a comparison, and not an assignment?

PCs used a series of beep codes to indicate system problems during boot since there is a small window where nothing can yet be displayed.

I,m stating equality,I'm not assigning mind to blown.
