1. 8. 3. The Lifetime of an Object

The process of disposing of dead objects is called garbage collection.
Encouraging the Java Virtual Machine (JVM) to do some garbage collecting and recover the memory.


class Sphere {

  double radius; // Radius of a sphere



  Sphere() {



  }



  // Class constructor

  Sphere(double theRadius) {

    radius = theRadius; // Set the radius



  }

}



public class MainClass {

  public static void main(String[] arg){

    Sphere sp = new Sphere();

    

    System.gc();

  }



}
