Create an abstract class Student From this class, derive 2 subclasses Fulltime Student and Part time Student The Student class has the following attributes: A student number and a date of birth The Student class has the following methods: O A default constructor and an overloaded constructor with 2 arguments Set and get methods Abstract methods setValue and getValue The Full time Student class has the following attributes Major subject - String object The Full Time Student class has the following methods o A default constructor and an overloaded constructor with 3 arguments Overridden methods-setValue and getValue for the subject The Part time Student class the following attributes: Elective Course String object The Part time Student class has the following methods: o A default constructor and an overloaded constructor with 3 arguments o Overridden methods setValue and getValue for the elective course Write a main class to test each of these classes. In your main method create an array of 4 Student objects instantiate the first and second element with the Full Time Student class instantiate the third and fourth element with the Part time Student class The first element should use values from the overloaded constructor he second element should use values from the set methods. the third element should use values from the default constructor e fourth element should use values from the set methods





Thats the instructions and im lost on making the array part, I would extremely grateful for anyone who can help me with thanks in advance

What I have tried:

<pre>
public abstract class TestYongo {
	
	public int number;
	public int dob;
	
	public TestYongo()
	{
		number=0;
		dob=0;
	}
	public TestYongo(int n,int d)
	{
		number=n;
		dob=d;
	}
	public void setnumber(int n)
	{
		number=n;
	}
	public void setdob(int d)
	{
		dob=d;
	}
	public int getNumber()
	{
		return number;
	}
	public int getDOB()
	{
		return dob;
	}
	public abstract void setValue();
	public abstract String getValue();
	
	

}



public abstract class FulltimeStudent extends TestYongo {
	
	public String subject;
	public FulltimeStudent(String s)
	{
		subject=s;
	}
	public void setValue(String s)
	{
		subject=s;
	}
	public String getValue()
	{
		return subject;
	}
}


public abstract class ParttimeStudent extends TestYongo {
	
	public String psubject;
	public ParttimeStudent(String s)
	{
		psubject=s;
	}
	public void setValue(String s)
	{
		psubject=s;
	}
	public String getValue()
	{
		return psubject;
	}

}
<pre>
public class Test {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		TestYongo t[]=new TestYongo[4];
		
		for(int i=0; i<4;i++)
		{
			t[i]=new TestYongo();
		}
	}

}
