eg: 1~qual~34 29~qual~39 3~pend~89 4~sub~24 5~notqual~28 Now, I want these things in order. It means sub should be first, then qual,then pend, then notqual. Wanted order is like this : 4~sub~24 then 1~qual~34 then 29~qual~39,then 3~pend~89 then 5~notqual~28. can anyone tell me how to do this.
You can use the method sort(List, Comparator) in the class java.util.Collections. The first argument to this method is your Vector, the second is a Comparator object that you have to write which determines the sort order.
Look those classes up in the API documentation and write some code. If you get stuck, please post your code here and explain where you get stuck.
