Implement the Computer problem using the Abstract Factory pattern.

public abstract class Computer { public abstract String getRAM(); public abstract String getCPU(); @Override public String toString(){ return "RAM= "+this.getRAM()+", CPU="+this.getCPU(); } } public class PC extends Computer { private String ram; private String cpu; public PC(String ram, String cpu) { } //Override public String getRAM() { } //Override public String getCPU() { } } public class Server extends Computer { ......... }

public interface ComputerAbstractFactory {

public Computer createComputer();

} public class PCFactory implements ComputerAbstractFactory { private String ram; private String cpu; public PCFactory(String ram, String cpu) { } //Override public Computer createComputer() { ........... }

} public class ServerFactory implements ComputerAbstractFactory { ............ } public class ComputerFactory {

public static Computer getComputer(ComputerAbstractFactory factory) { ..................... } } Create a class Test to test the class Computer Factory.
