Is it possible to call destroy () method from init () and service () methods in Servlet?

Question

Is it possible to call a method destroy()from methods init()and service()in a servlet? I have many confusing answers on blogs.

As I understand it, when we call a method destroy()from init(), it must call and destroy the servlet if we redefine it destroy()in our servlet. Then the servlet will be destroyed.

Is this understanding correct?

Not everything is right.

destroy() , . . . destroy() . , , init().

.

private SomeExternalResource someExternalResource;

@Override 
public void init() {
    someExternalResource = new SomeExternalResource();
}

@Override
public void destroy() {
    someExternalResource.close();
}
