Hi krish4u,

The line you posted contains a ternary operator. It is basically a shorter way for a one-line if-else statement.

It means:

if(nameParts.size() > 1)
{
    contact.LastName =  nameParts[nameParts.size()-1];
}
else
{
    contact.LastName =  nameParts[0];
}

Also check out the documentation (item 11) (https://www.salesforce.com/us/developer/docs/apexcode/Content/langCon_apex_expressions_operators_understanding.htm).

Best regards,
