As long as you are assured that every element in the vector is a String, try this:

The "toArray()" method in Vector is overloaded; if you don't call the correct one it will only return an array of Object. If you want to cast it to some other type, you have to pass in a "seed" array of that type. As shown in this example, it can have a length of zero.

However, if you are not assured that every object is a String, you will have to iterate through the Vector and invoke toString() on each of the Vector's elements (adapting the previous example):
