Garbage Collection

• While Java has automatic garbage collection, there is a keyword that can be used to clean up stuff semi-manually. When an object reference, the class that was used can use the function finalize() to clean up anything else.
• The Object class has a default finalize() that can be overrode. Since every class inherits from the Object class, finalize() can be used by any Java object.

class A
{
    int i = 50;

    @Override
    protected void finalize() throws Throwable
    {
        System.out.println("From Finalize Method");
    }
}
