Cloning via the Cloning library

A deep copy is needed when an object depends on another object. Performing a deep copy means copying the object, including its chain of dependencies. For example, let's assume that Point has a field of the Radius type:

public class Radius {  private int start;  private int end;  // getters and setters}public class Point {  private double x;  private double y;  private Radius radius;  public Point(double x, double y, Radius radius) {    this.x = x;    this.y = y;    this.radius = radius;  }  // getters and setters}

Performing a shallow copy of Point will create a copy of x and y, but will not create a copy of the radius object. This means that modifications that affect the radius object will be reflected in the clone as well. ...
