These days, it's recommended to not use Vector. Use a different type of list, like ArrayList, instead. If you're curious for the reasoning behind this, I'd recommend a quick search on this forum for "vector arraylist" in the subject. (Note that the search page link is at the top right of this page.) Also, you might like to read the JavaWorld ... |

Calling a full sort routine on every insertion seems like overkill to me (especially quicksort, which is poor at almost sorted sets!). I can think of two approaches that will be better - which I'd prefer would depend on how I was expecting it to be used. - On each insertion, work out the correct point of insertion and just insert ... |

Thanks for the help everyone, it is very much appreciated. Don't knock the teacher, he's a good guy and I understand why he assigned it, I might not agree with it considering the amount of time we didn't spend on vectors this semester but meh, what can I do. It's a learning experience. Thanks again everyone |

Hi all, I have a Vector of Objects with several properties (int, string and other Objects as well). I would like to sort the vector according to properties. I know how to do this when you have only one property, but I couldn't find any example of objects inside the vector with multiple (and heterogeneous) properties. Any hint? Thanks |
You could wrap the inside Vector inside of another class, implement comparable with that class, and construct the comparison in such a way that it will always compare the first value contained in the first vector against the first value contained in the second vector. However, what you should do is make a class to contain the info, and have it ... |
