1、表层克隆

  1. public class Snake implements Cloneable
  2. {
  3. private Snake next;
  4. private char c;
  5. Snake(int i, char x){
  6. c = x;
  7. if(--i > 0){
  8. next = new Snake(i,(char)(x+1));
  9. }
  10. }
  12. public void increment(){
  13. c++;
  14. if(next!=null){
  15. next.increment();
  16. }
  17. }
  19. public String toString(){
  20. String s = ":"+c;
  21. if(next!=null){
  22. s += next.toString();
  23. }
  24. return s;
  25. }
  26. public Object clone(){
  27. Object o = null;
  28. try{
  29. o = super.clone();
  30. }catch(CloneNotSupportedException e){}
  31. return o;
  32. }
  33. public static void main(String[] args)
  34. {
  35. Snake s = new Snake(5,a);
  36. System.out.println("s ="+s);
  37. Snake s2 = (Snake)s.clone();
  38. System.out.println("s2 ="+s2);
  39. s2.increment();
  40. System.out.println("after s2.increment, s="+s+" s2 ="+s2);
  41. }
  42. }

此时的输出结果：
s =:a:b:c:d:e
s2 =:a:b:c:d:e
after s2.increment, s=:a:c:d:e:f s2 =:b:c:d:e:f

  3. private Snake next;
  4. private char c;
  5. Snake(int i, char x){
  6. c = x;
  7. if(--i > 0){
  8. next = new Snake(i,(char)(x+1));
  9. }
  10. }
  12. public void increment(){
  13. c++;
  14. if(next!=null){
  15. next.increment();
  16. }
  17. }
  19. public String toString(){
  20. String s = ":"+c;
  21. if(next!=null){
  22. s += next.toString();
  23. }
  24. return s;
  25. }
  26. public
