Is there a Java Drawing Component or Library with scaling?

Question

Java

Good day to all!

We are developing a Java SE (SWING) application. We use either the .draw() of the component or the Graphics all the time, so the question is:

Is there an open-source component or can anyone recommend a good, simple drawing library?

Tried G/ — not absolutely convenient. You just need, say, call 1 method.

Just a bare minimum to draw shapes with zoom and scroll.

Answer 1

See what exactly you need. We use JFDraw for vector graphics tasks .
There is also JGraph
There is Java Open GL

Such things are really mass-produced, but it's cheaper and easier to solder yourself or find a radio amateur.

Answer 3

Connect the player to the sound input of the computer and the headphones only to the computer. Adjust the volume sliders. Profit.
But the player with the player is problematic. Since if there is sound in one player, then the output of the other player will be like an input and you can burn it ... and even extra resistance.
You can make a hardwire switch.
Specify what is needed.

Answer 4

To answer the question, you need to know why we need it.
