    id = val;
    return this;
}

from below if statement i want to set builder id = 1ac. How can I do that. Thank you

if (blah blah)
{
    id = "1ac";
}

I think you’re looking for:

if(someCondition) builder.id("1ac");

The id method is written so that you pass it the value you want to set and then it returns this so you can chain calls together to set different values with a single statement.
