Question

I’m getting an array with fixed size of let’s say 20.

I have to set each array element in a bean property, so my bean has 20 properties.

Here’s my current approach:

Object[] record = { "0", "1", "2", ...."19" };

for (int j = 0; j < record.length; j++) {
    if (j == 0) {
        bean.setNo((String) record[j]);
    }
    if (j == 1) {
        bean.setName((String) record[j]);  
    }
    if (j == 2) {
        bean.setPhone((String) record[j]);  
    }
    // so on and so forth...
}

This is how i’m setting every property of bean from array.

Here i have 20 elements in array.

So to set 20th element it is checking 20 conditions.. Performance issue..

Any optimized technique is appreciated…

Thanks in advance…

Answer 1

One way of doing this is :

Try this::

     Object[] record = BeanList.get(i);
     int j = 0;
     bean.setNo((String) record[j++]);
     bean.setName((String) record[j++]);  
     bean.setPhone((String) record[j++]);
