CPU Interface Exercises (only this program proves that a classmate is really poisonous!) Toxic!!! ）

1 Creating an interface

 Package Lianxi;  Public Interface ICPU {    public  boolean neicun ();   Memory Interface     }

2 Create a class to connect to this interface

 Package Lianxi;  Public class Implements icpu {    @Override    publicboolean  Neicun () {                System.out.println (" CPU memory is too small ");         return true ;    }}

3 Creating a parent class

 Public classComputer {PrivateICPU CPU;  Publicicpu Getdiannao () {returnCPU; }     Public voidSetdiannao (Icpu CPU) { This. CPU =CPU; }     DoubleRongliang; BooleanCP () {Booleanrtn=true; if(rongliang>50) {System.out.println ("Installed a" +rongliang+ "CPU"); RTN=false; }Else if(cpu==NULL) {System.out.println ("CPU not Installed"); RTN=false; }Else{RTN= This. Cpu.neicun (); }return true; }    }

4 Creating subclass Calls

 Package Lianxi;  Public class Ceshi {    publicstaticvoid  main (string[] args) {        // TODO Auto-generated method stubs        Computer cop=New  computer ();        Cop.rongliang=34;
System.out.println ("When the capacity is" +cop.rongliang+ ");        Cop.setdiannao (new  Cpuceshi ());        Cop. CP ();}    }

 Package Lianxi;  Public class Ceshi {    publicstaticvoid  main (string[] args) {        // TODO Auto-generated method stubs        Computer cop=New  computer ();        Cop.rongliang=70;        System.out.println ("When the capacity is" +cop.rongliang+ ");        Cop.setdiannao (new  Cpuceshi ());        Cop. CP ();}            }
