Concept :The factory method pattern defines an interface for creating objects , letting subclasses decide which class to instantiate. The factory method defers the instantiation of a class to its subclasses. composition role :In the simple factory model, we put the dynamic creation of specific product class objects in the factory class. Because it is responsible for the branch judgment of the specific product object, it is easy to produce high coupling. Based on the dependency reversal princip

-capable of outputting more than one string Print-only one string is output and always returns 1 Tip: Echo is slightly faster than print because it does not return any values.1) echo is a language structure that can be used with or without parentheses: Echo or Echo ().Use the echo command to display strings and variables echo "这段话", "由", "多个", "字符串", "串接而成。";//这段话由多个字符串串接而成。2) Print is also a language structure and can be used without brackets: print or print ().4.PHP Data typesString,

numbersJavaScript has only one numeric type. Numbers can be with decimal points or without:Instancevar x1=34.00; Use a decimal point to writevar x2=34; Do not use the decimal point to writeLarge or small numbers can be written by means of scientific (exponential) notation:Instancevar y=123e5; 12300000var z=123e-5; 0.00123Try it?You'll learn more about numbers in the Advanced section of this tutorial.JavaScript BooleanBoolean (logic) can have only two values: TRUE or FALSE.var x=true;var Y=false

1. What is an array?An array object uses a separate variable name to store a series of values. That is, the array can store all values with a variable name, each of which has its own ID, so it is easy to access any value with the variable name.2. Creating an array(1) General method:var mycars=new Array ();Myarr[0]= "Volvo";Myarr[1]= "BMW";Myarr[3]= "Saab";(2) Concise way:var mycars=new Array ("Volvo", "BMW"

I used this VMWare Workstation in a MAC to successfully flash the PPK on a 335xi E90 today. It shouldn ' t is too hard-make it work with fusion I don ' t think. Ista/p 3.56.1.002 is working awesome! A uncompressed VM size with ista/p is 280GB.Note:have to run it on Bootcamp until we can find a workaround for Mac usersVery Important reference!!Http://obd2-diag.blogspot.com/2016/09/bmw-inpa-vmware-solution-on-windows-710.htmlHere is some tips and ideas
