Kui palju niite luuakse JVM rakenduse käivitamisel?

When launching a JVM application, several threads are created by default, among which the main ones are:

• main — the main thread where your application's main method runs.
• GC (Garbage Collector) threads — responsible for garbage collection.
• Finalizer Thread — thread for executing finalize methods.
• Reference Handler Thread — processes weak, soft, and phantom references.
• Signal Dispatcher — handles OS signals.

The exact number of threads depends on the JVM implementation and settings, but usually, there are about 5 to 10 threads immediately after startup. Additional threads are created as needed, for example, for thread pools, asynchronous tasks, etc.
