what is Thread Leak and Thread Dump in Java

Question

Can you please Explain me what is Thread Leak and Thread Dump in Java? I am just confuse about thread Dump.

Let me know the other way of creating thread except Thread class and runnable interface?

Answer 1

From the docs :

The thread dump is a snapshot of exactly what's executing at a moment in time

And thread leak is when we dont close the thread properly then the number of unused threads grows with time.
