/* Bridging (Bridge) mode, is a structured pattern *  * The abstraction and implementation decoupling, so that they can be independent changes, that is, the strong association between them into a weak association, * refers to the abstraction and implementation of a software system between the use of a combination/aggregation relationship rather than inheritance, So that the two can change independently. */public class Test {public static void main (string[] args) {/* * In this case: there is a strong correlation between the phone and the phone shell: either the phone corresponds to a shell (Basecellphoneshell), Either the shell corresponds to a cell phone (basecellphone) * Mobile phone can have multi-dimensional changes, such as according to the brand division, according to the size of the division according to the individual needs of the mobile phone shell also has a multidimensional change, because it to adapt the above divided mobile phone * will bridge in the Basecellphone , the aggregation is connected to the Basecellphoneshell */basecellphone cellphone = new cellphone (); Cellphone.setshell (new Cellphoneshell ());// converged access cellphone.mapping ();}}
