In my speedometer application, how do I contain the changing speeds in my location.getSpeed() function in an array so that I can find the highest speed using the math.max function?

   public class Main3Activity extends AppCompatActivity implements 
      android.location.LocationListener {
  int arr[];
private float [] speeds=new float[10];



    public  float boo;
       @Override
         protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main3);
        LocationManager lm = 
   (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != 
  PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,this);
        this.onLocationChanged(null);
      final  TextView mTextField=(TextView)this.findViewById(R.id.textView);

        new CountDownTimer(11000, 1000) {

            public void onTick(long millisUntilFinished) {
                mTextField.setText("" + millisUntilFinished / 1000);
            }

            public void onFinish() {
                Intent myIntent = new Intent(Main3Activity.this,
                        aftergame.class);
                startActivity(myIntent);
            }
        }.start();


    }
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case 1: {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                } else {
                    // permission denied, boo! Disable the
                    // functionality that depends on this permission.
                }
                return;
            }
            // other 'case' lines to check for other
            // permissions this app might request
        }
    }
    public boolean checkLocationPermission()
    {
        String permission = "android.permission.ACCESS_FINE_LOCATION";
        int res = this.checkCallingOrSelfPermission(permission);
        return (res == PackageManager.PERMISSION_GRANTED);
    }


    @Override
    public void onLocationChanged(Location location) {
        int cpeedi;

        TextView txt=(TextView)this.findViewById(R.id.st);
if(location==null){
txt.setText("0 m/s");

}else{
 float  cpeed=location.getSpeed();
 float cpeed1=location.getSpeed();


cpeedi=(int)cpeed;
txt.setText(cpeedi + " m/s");



}







}




    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {

    }

}
