toString():
The toString() function given by the java.lang.Object returns a string, which consists of the class name followed by an "@" sign and then unsigned hexadecimal presentation of the hashcode, As Set@162b91. This hexadecimal presentation is not what the users of your class want to see.
clone():
You have to override the clone() method very judiciously. Implementing a properly working clone method is complex and it is rarely used. You are better off providing some alternative defines of object copying or simply not giving the capability.

protected void finalize() throws Throwable {
try{
//finalize subclass state
}
finally {
super.finalize();
