Difference between AlertDialog.builder's obj.create() vs obj.show() vs obj.create().show()

Question

Is there any difference between .create() and .show() methods of AlertDialog's builder class? Like when we create an alert dialog using:

AlertDialog.Builder builder = new 
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setMessage("");
builder.setPositiveButton(....)
builder.setNegativeButton(....)

What is recommended pratice to use and why?

builder.create() //I have seen this creates and displays the dialog

OR

builder.show() //this also displays the dialog

OR

builder.create().show() //well same thing

I have read the documentation. But was unable to make any sense from it. Any ideas ?

Answer 1

obj.create()-For create Dialog

obj.show()-For show Dialog <- without it you cant show dialog if you created.

and

obj.create().show()-create and show Dialog i mean both same as above two in one statement.
