Thread: Basic program help

Hello, I've recently started a Computer Science course but due to illness I've missed the majority of the lectures in the first 3 weeks. I have been set a basic task where I have to create a Class that will model a mobile phone.
It will have fields that correspond to the type of phone, memory, service provider, contract type, camera res, phone battery.

It Will have a constructor for the class to pass arguments between the attributes with other fields set to default values.

Once the phone is sold it will need mutator methods to set the type of contract and the service provider. These will be setProvider() and setContractType()

A mutator method chargeUp() shouldalso simulate fully charging the phone. Accessor methods are needed to to retrieve information from fields. getType, getProvider etc.


This is a brief overview of the task and I'm not sure where to go and further than creating the class and variables. I'd appreicate if someone could advise on where to go from there with a brief explanation so I can continue.

Thanks in advance.

Start by going through the assignment a line at a time and doing exactly what it says. For example:

// create a Class that will model a mobile phone
public class MobilePhone
{
 
}

You fill in the rest. Come back when you need help.

public class Mobile
{
    //Declaring the variables of the Class.
 
    private int ScreenSize;
    private String PhoneType; 
    private int Memory;
    private String ServProv;
    private String Contract;
    private float CamRes;
    private int Battery;
    private boolean Gps;

This is what I put in, but the String doesnt come up in red like the other data types and I'm not sure why. I'm given this by the IDE (BlueJ) to do next.

/**
     * Constructor for objects of class Mobile
     */
    public Mobile()
    {
        // initialise instance variables
 
    }

Not completely sure what to do next.

Keep going through the assignment line by line and doing what it says. I'm not sure why you're distracted by what BlueJ says to do (not even sure what that means), but keep working on the assignment. BlueJ is not being graded for your work, you are.
