Is it possible to write return statement in if block using java?

I want to return Vector according to if block

But the Code give me Error As following

"Add return statement " is it possible to write return statement in if block?

public static  int[] zeroVectorBinning1( ImageFloat32 angle,ImageFloat32 Magnitude )
{
for (int NumberOFChanks=0;NumberOFChanks<locations_original.size();NumberOFChanks++)
            {
                for(int i=0;i<angle.getHeight();i++)
                    for(int j=0;j<angle.getWidth();j++)
                {
                    int  orientaionVal=(int) angle.get(j, i);

                     if(orientaionVal<=0)
                        {int magnitudeVal=(int) Magnitude.get(j, i);
                        int[] Vector = new int[19];
                        Vector=zeroVector(19);
                        Vector[0]=magnitudeVal;
                        return Vector;
                        }
                    else if(orientaionVal<=20)
                        {int magnitudeVal=(int) Magnitude.get(j, i);
                        int[] Vector = new int[19];
                        Vector=zeroVector(19);
                        Vector[1]=magnitudeVal;
                        return Vector;
                        }
                    else(orientaionVal >= 0 && orientaionVal <=20)

                        {
                        int magnitudeVal=(int) Magnitude.get(j, i);
                        int[] Vector = new int[19];
                        Vector=zeroVector(19);
                        Vector[0]=magnitudeVal;
                        Vector[1]=magnitudeVal;
                        return Vector;

                        }

                }
            }

    }
