My code
How do you call the superclass constructor in the subclass to make this code work?
class Ale
protected int x = 1;
public Ale( int xx )
x = xx;
class Bud extends Ale
private int y = 2;
public void display()
System.out.println("x = " + x + " y = " + y);

public Ale(int xx)
x = xx;
class Bud extends Ale
Bud()
super(75);
private int y = 2;
public void display()
System.out.println("x = " + x + " y = " + y);
