New to Java

i am passing an array b[] to editArray() which should return an edited array

    byte[] b = {1, 2, 3, 4};
    byte[] b2 = editArray(b);
    for (byte t: b)  System.out.print(t + ", "); System.out.println();		
    for (byte t: b2) System.out.print(t + ", ");

editArray();

public static byte[] editArray(byte[] bArray){
    for(int i=0; i<bArray.length; i++) bArray[i] = 0;
    return bArray;
    }

since java is passing by values, i was expecting b[] to have no changes.
here is the output

0, 0, 0, 0, 
0, 0, 0, 0,

* please can any one explain this for me, in some blogs the says : "Java passes objects as references passed by value". i cant get it.*
