Java Comparator class to sort particular object array

Question

I have a float array and a String array. each float value match with a specific String. I would like to sort the float array keeping the own string using :

Answer 1

I solved merging both answare:

public class VoiceRecognitionDemo extends Activity implements Comparator() {
            @Override
            public int compare(ResultVoiceObject arg0, ResultVoiceObject arg1) {
                return Float.compare(arg0.getRanking(), arg1.getRanking());
            }
        });  

    }


public int compare(ResultVoiceObject lhs, ResultVoiceObject rhs) {
    // TODO Auto-generated method stub
    return 0;
}

}

Where:

 public class ResultVoiceObject
 {

 private  String frase;
 private float ranking;
 public ResultVoiceObject(String f, float r) 
   {
    this.frase=f;
    this.ranking= r;
   }  
 }

Another way is:

ADD

import java.util.Arrays;

import java.util.Comparator;

REMOVE: implements Comparator and the compare methos out onActivityResult
