3: Static Factory method

Package Com.study.spel;


Import Java.util.HashMap;
Import Java.util.Map;


/**
* Static Factory Method: A static method that invokes a class directly can return an instance of a bean

*/
public class Staticfactory {
private static map<string,car> cars=new hashmap<string,car> ();
Static
{
Cars.put ("Audi", New Car ("Audi", "3000000", 110.0));
Cars.put ("Ford", New Car ("Ford", "2000000", 210.0));
Cars.put ("Didi", New Car ("Didi", "1000000", 310.0));
}
Static Factory method
public static Car Getcar (String name)
{
return Cars.get (name);
}
}
