Setters AND ( not OR or VS ) builder patterns

Question

I have a situation where I use a builder pattern for constructing an object. Best example to give is the pizza code

public class Pizza {
  private int size;
  pr         


        

Answer 1

you can use @Builder(toBuilder = true).

@Builder(toBuilder = true)
class Pizza {
int val;
}

Pizza ob = Pizza.builder().val(10)build();

Pizza newObj = ob.toBuilder().val(11).build();
