method.Template methodA template method is defined in an abstract class that combines basic operational methods to form a total algorithm or a method of total behavior.An abstract class can have any number of template methods, not limited to one. Each template method can invoke any number of specific methods.Basic methodsThe basic method can be divided into three kinds: abstract method, Concrete method (concrete methods) and hook method.Abstract Method: An abstract method is declared by an abst

The design pattern is called the procedure Ape's internal strength, before fragmented saw a large part, but oneself has summed up. So this is summed up here. It is worth mentioning that design patterns are not unique to Java. Because of always doing Android. Here we use Java
java Design PatternsDesign Pattern ClassificationThe Java design pattern can be divided into three categories according to the creation pattern, the structure pattern and the behavioral pattern:
Create pattern
Single-instance mode, Factory mode, abstract Factory mode,Builder mode, prototype mode
