Return in void method

Question

Is there void method that has return keyword?
Because I saw one of them in a code related to the nodes of LinkedList.
I want to know what's returned in this void method?

It is sample:

public void insertAfter(Node prev_node, int new_data)
{
    if (prev_node == null)
    {
        System.out.println("The given previous node cannot be null");
        return;
    }
//It's part of a code!

Answer 1

return is a reserved keyword to exit/end a method, with or without a value

Answer 2

No value is returned. Only the program control flow is returned to the point of (just after) the method invocation.

Answer 3

If the method returns void then return; just exits out of the method at that statement.
