java - Finding minimum value of my ArrayList of float values -

i'm having sorts of problems trying expected quite simple. have arraylist of float values, , want return minimum value in list float. expected work:

public float getmin(){ float min = collections.min(arrays.aslist(listofthings))); return min; }  

but keep running loads of incompatibility problems.

what's efficient way of doing this?

thanks

if use collection generic, collection.min returns object should convert it.

do this:

object obj = collections.min(arraylist); float f = float.parsefloat(obj.tostring()); return f.floatvalue(); 

or define arraylist

arraylist<float>  

and don't need convert it.
