    Well, I am in the middle of doing a programming question for an assignment. Think I have gotten most of it right but its just killing me that I don't have enough time to finish everything... (Due in later tonight). I still have to start the 2nd question myself, but this is what I got for the first one!

    This is the question:
    Part 1 (50 marks)
    a) Write the Java code for a class called Patient.
    • The Patient class should have the following four private instance variables:
    o name
    o iDNumber
    o age
    o gender
    Choose the correct type for each of the instance variables.
    • Include a default constructor.
    • Include a constructor that accepts four parameter values: name, iDNumber, age, and gender.
    • Include get and set methods for each of the instance variables.
    • Include a method called print() that prints the value of all the instance variables to the screen, e.g.
    Patient name: Joe Bloggs
    IDNumber: 520
    Age: 86
    Gender: Male
    b) Write the Java code for a class called PatientTestApplication (containing a public static void main(String [] args) method) which tests the two constructors, the get and set methods, and the print() method of the Patient class.
    • This class should create two objects of the class Patient, using each constructor in the Patient class definition.
    • It should then test all the get and set methods on each object.
    • It then uses the print() method on both objects to print the object’s details to screen.

    This is what i have got so far...

    Code:
    public class Patient
    
    
    
    	{
    
    	//Attributes: Object characteristics
    	private String name;
    	private int iDNumber;
    	private int age;
    	private String gender;
    
    	public Patient()
    		{
    			name = "none";
    			iDNumber = 0;
    			age = 0;
    			gender = "none";
    		}
    
    	public Patient(String n, int i, int a, String g)
    		{
    			 name = n;
    			 iDNumber = i;
    			 age = a;
    			 gender = g;
    		}
    
    
    
    
    	//Methods: object behavior, mutator method
    	public void setName(String n)
    		{
    			name = n;
    		}
    		//accessor methods
    		public String getName()
    			{
    				return name;
    		}
    
    
    
    
    		//Methods: object behavior, mutator method
    	public void setIdNumber(int i)
    		{
    			iDNumber = i;
    		}
    
    	//accessor methods
    	public int getiDNumber()
    		{
    			return iDNumber;
    		}
    
    
    	//Methods: object behavior, mutator method
    	public void setAge(int a)
    		{
    			age = a;
    		}
    
    	//accessor methods
    	public int getAge()
    		{
    			return age;
    		}
    
    
    
    	//Methods: object behavior, mutator method
    	public void setGender(String g)
    		{
    			gender = g;
    		}
    	//accessor methods
    	public String getGender()
    	{
    		return gender;
    	}
    
    
    
    	}
    =======================================================
    And this is my test... it doesnt seem to work properly and I dont know why :(
    
    
    public class PatientTest
    {
    
    	//this is an array of strings
    	public static void main(String [] args){
    
    
    		Patient p1 = new Patient("Joe Bloggs", 4125, 45, "Male");
    
    		Patient p2 = new Patient();
    
    
    		 // new set methods to overwrite the old ones on patient 2
    		System.out.println("Name:"+ p2.getName());
    		System.out.println("iDNumber:"+ p2.getiDNumber());
    		System.out.println("Age:"+ p2.getAge());
    		System.out.println("Gender:"+ p2.getGender());
    
    		p2.setName("Larry");
    		p2.setIdNumber(12345);
    		p2.setAge(25);
    		p2.setGender("male");
    
    
    		  //gets code from patient and gives values
    		System.out.println("Name:"+ p1.getName());
    		System.out.println("iDNumber:"+ p1.getiDNumber());
    		System.out.println("Age:"+ p1.getAge());
    		System.out.println("Gender:"+ p1.getGender());
    
    		//this is default code here which has no values in patient
    		System.out.println("Name:"+ p2.getName());
    		System.out.println("iDNumber:"+ p2.getiDNumber());
    		System.out.println("Age:"+ p2.getAge());
    		System.out.println("Gender:"+ p2.getGender());
    	}
    
    
    
    
    }
    
    If anyone can help me out it would be amazing, until then I'm going to start my 2nd question... FML :(
