I have this piece of code:

```
public lot merge (lot otherlot){
    wafer[] mWaferarray = new wafer[16];
    byte[] bytearray = new byte[16];
    wafer resultwafer = new wafer(bytearray);
    wafer w1;
    wafer w2;
    int i;
    int[][] assignmentmatrix = HungarianAlgorithm.computeAssignments(convertinttofloat (solutionmatrix(otherlot)));

    for (i=0; i != assignmentmatrix.length ;i++){

        w1 = otherlot.getWaferarray()[assignmentmatrix[i][0]];

        w2 = getWaferarray()[assignmentmatrix[i][1]];

        resultwafer.setWafer(w1.wafercompare(w2));

        mWaferarray[i] = resultwafer;
        mWaferarray[i].print();

    }
    System.out.println("HERE\n");
    mWaferarray[5].toString();

    resultlot = new lot(mWaferarray);
    resultlot.print();// Problem occurs here.

    return resultlot;

}

```

As you can see I create an array of wafers (selfdefined class). Then I fill this up with new wafers. When I print this array (mWaferarray[i].print()) it gives me the wanted results. But when I go out of the "for"-loop the array is broken and it is as if the last item I add to mWaferarray fills it up (the entire array, 16 long, is filled with this wafer). 
So if run this program this is what I get:

```
1011110010111100
0011011111111110
0111110111101101
1010111001101111

0101111011011010
0101111011011010
0101111011011010

```

As you can see it is as if the array is filled with the last wafer.

I have been looking at this for some time now, I hope you guy can help me out.

Thx in advance

PS: my print functions are written like this:

```
    void print(){
    int j;
    for (j=0; j != waferarray.length ;j++){
        waferarray[j].print();

        }

    }

```

EDIT: added code for lot

this is the beginning of the lot class

```
public class lot {

wafer[] waferarray = new wafer[16];
lot resultlot;

public lot (wafer wafer1,wafer wafer2,wafer wafer3,wafer wafer4,
        wafer wafer5,wafer wafer6,wafer wafer7,wafer wafer8,
        wafer wafer9,wafer wafer10,wafer wafer11,wafer wafer12,
        wafer wafer13,wafer wafer14,wafer wafer15,wafer wafer16){

    waferarray[0] = wafer1;
    waferarray[1] = wafer2;
    waferarray[2] = wafer3;
    waferarray[3] = wafer4;
    waferarray[4] = wafer5;
    waferarray[5] = wafer6;
    waferarray[6] = wafer7;
    waferarray[7] = wafer8;
    waferarray[8] = wafer9;
    waferarray[9] = wafer10;
    waferarray[10] = wafer11;
    waferarray[11] = wafer12;
    waferarray[12] = wafer13;
    waferarray[13] = wafer14;
    waferarray[14] = wafer15;
    waferarray[15] = wafer16;

}

public lot (wafer[] thiswaferarray){

    waferarray = thiswaferarray;

}

```
