First of all, Person doesn't have a variable called status. So you can't call it in super. Well you can, but it will set something else to the value of status, not what you wanted. Also, the superclass of Staff doesn't have a title.

I compiled, under a file called Testing.java, and got 8 errors:

You misspelled address for one of those errors.

Under salary, you put it in quotes so now it's a String.

You can't go using super unless you're referring directly to the same spot in the parent class.

For instance,

public class Point1D
{
private int x;
 
public Point1D()
{
setX(0);
}
 
public Point1D(int x)
{
setX(x);
}
 
public void setX(int x)
{
this.x = x;
}
 
public int getX()
{
return x;
}
 
public String toString()
{
return ("X: " + getX());
}
}

 
public class Point2D extends Point1D
{
private int y;
 
public Point2D()
{
super();
setY(0);
}
 
public Point2D(int x, int y)
{
super(x);
setY(y);
}
 
public Point2D(int y)
{
super();
setY(y);
}
 
public void setY(int y)
{
this.y = y;
}
 
public int getY()
{
return y;
}
 
public String toString()
{
 
return (super.toString() + " , Y: " + getY());
}
}

 
public class Point3D extends Point2D
{
private int z;
 
public Point3D()
{
super();
setZ(0);
}
 
public Point3D(int x, int y, int z)
{
super(x,y);
setZ(z);
}
 
public Point3D(int z)
{
super();
setZ(z);
}
 
public void setZ(int z)
{
this.z = z;
}
 
public int getZ()
{
return z;
}
 
public String toString()
{
return (super.toString() + ", Z: " + getZ());
}
}

I've corrected 4 of the 8 errors in your code. Try and see if you can fix the other 4 now.

Also, any particular reason why status is final?
