Question
hello, i really need help with my project without any changes in my code i just need someone to :
1.Design or do a general structure by a UML diagram or any other way to Describe the major steps in this program (the program contains 8 classes).
2. add programs%u2019 codes. Your code must contain a block comment
describing its purpose, descriptive comments for each of the methods, and
a few in-code comments, where appropriate.
f. Testing: Describe how to test this program along with a block comment
at the end containing sample output.
this is the code:
computer class code:
public class Computer extends ElectronicDevice{
private static int counter =0;
public Computer(String mnfctr, String model, String prcssr, double current, int voltage){
super(mnfctr, model, prcssr, current, voltage);
counter++;
} public static int getCounter(){
return counter;
}
}
Desktop class code:
public class Desktop extends PersonalComputer{
private int PCIslots;
private static int counter = 0;
public Desktop(String mnfctr, String model, String prcssr, double current, int voltage, double HDsize, int PCIslots){
super(mnfctr, model, prcssr, current, voltage, HDsize);
this.PCIslots = PCIslots;
counter++;
}
public static int getCounter(){
return counter;
}
public String toString(){
return "A "+ this.getClass() + " " + super.getClass() +" " + super.toString() + "and " + PCIslots + " PCI slots.";
}
}
Device class code:
public class Device{
private String mnfctr;
private String model;
private String prcssr;
private double current;
private int voltage;
private static int counter =0;
public Device(){}
public Device(String mnfctr, String model, String prcssr, double current, int voltage){
this.mnfctr= mnfctr;
this.model = model;
this.prcssr = prcssr;
this.current = current;
this.voltage = voltage;
counter++;
}
public String toString(){
return "manufactured by "+ mnfctr +" , model " +model +", using " +current +" amps, at " +voltage +"volts, CPU " + prcssr;
}
public int compareTo(Device device){
return this.mnfctr.compareTo(device.mnfctr);
}
public static int getCounter(){
return counter;
}
public String getMnfctr(){
return mnfctr;
}
}
Electronic Device class code:
public class ElectronicDevice extends Device{
private static int counter =0;
// public ElectronicDevice(){}
public ElectronicDevice(String mnfctr, String model, String prcssr, double current, int voltage){
super(mnfctr, model, prcssr, current, voltage);
counter++;
} public static int getCounter(){
return counter;
}}
