Difference Between Thread Class and Runnable Interface in Java
In this post, we will understand the difference between
Thread
It is a class.
It can be used to create a thread.
It has multiple methods such as ‘start’ and ‘run’.
It requires more memory space.
Since multiple inheritance is not allowed in Java, hence, after a class extends the Thread class, it can’t extend to any other class.
Every thread creates a unique object and associates with it.
Runnable
It is a functional interface.
It can be used to create a thread.
It has a single abstract method ‘run’.
It requires less memory space.
When a class implements the ‘runnable’ interface, the class can extend to other classes.
Multiple threads can share the same objects.
