Get float from vector

Question

Hello
Imagine:
float fff;
public void maxi(Vector v){
for(int z=0; z<v.size(); z++){
fff=v.get(z);
This code gives an error. v.get(z) gives an Object
and fff is a float.
in fact
v (a vector with floats) should give a float and not an object...
What is the problem?
Thanks

Vector is sort of depracated these days, use ArrayList instead.
But neither will hold primitive types like float, Lists always contain objects. If the values you want to store are floats then use you use the Float wrapper class.
Since version 1.5 this can be made to look simpler by two changes to the language, generics and autoboxing. Generics allow you to tell the compiler what your List is a List of, autoboxing automatically converts between, say, Float and float.
So you can handle your data like this:
List<Float> list = new ArrayList<Float>(10);  // List is going to contain only Float objects
list.add(12.5f);   // automatically converts literal from float to Float
list.add(10f);
float v = list.get(0);  // automatically converts Float retrieved to float.
