    for (int i = 0; i < 10; i++) {
        for (int j = 0; j < 10; j++) 
            buf.append(data[i][j]);
            buf.append(“\n”);
        }

        StringBuffer buf = new StringBuffer();
        collectRows(buf);
        return buf.toString();
    }
    
    void collectRows(StringBuffer buf) {
        for (int i = 0; i < 10; i++) 
            collectRow(buf, i);
        }
    }
    
    void collectRow(StringBuffer buf, int row) {
        for (int i = 0; i < 10; i++) 
            Buf.append(data[row][i]);
            buf.append(“\n”);
