corejava-OOPs: Can we override the constructors?

Constructors can´t be overridden. They´re not inherited. However, each subclass constructor has to chain either to another constructor within the subclass or to a constructor in the superclass.

A constructor can´t be overridden in similar class because both of them would have similar signatures and compiler error would be there.

for example:

public class Superclass
{
public Superclass(int x) {}

public Superclass(String y) {}
}

public class Subclass extends Superclass
{
public Subclass()
{
super(5); // chain to Superclass(int) constructor
}
}
The implication of constructors not being inherited is that you can´t do this:

// Invalid
Subclass x = new Subclass("hello");
