Difference between builder pattern and constructor [closed]

Answer 1

The constructor constructs the object you need, while the builder is a helper object to construct what you need. I think it is horrible!

1. It contradicts the natural, well learnt method of object creation. What new methods will they come up with next?
2. Instead of creating one object, you are forced to create two.
3. It is absolutely not necessary! We always had to prepare variables for function params and we never used a builder.

eg:

// a class with ctor that takes lots of params
class Params
{
    Params(int,int,int,String,char,boolean,int){}
}

// We dont need a builder.
// A builder will do the same following thing.
int p1 = 20;
int p2 = 40 + 40;
int p3 = (67 >> 1) * 3;
String p4 = "go" + "to" + "church";
char p5 = ' ' == 32 ? '5' : '7';
boolean p6 = true;
int p7 = MATCH_PARAMS;
new Params(p1,p2,p3,p4,p5,p6,p7);

//There is also this design pattern
new Params(
    20,
    40 + 40,
    (67 >> 1) * 3,
    "go" + "to" + "church",
    ' ' == 32 ? '5' : '7',
    true,
    MATCH_PARAMS
   );

At the end of the day if you are a fan of builders no problem. But when Android makes constructors deprecated I don't like that. It like, type type type; deprecated.
