Building a copy constructor in Java

Question

Can anyone help me with the code for building copy constructor in Java? I have tried with the code but was unable to write the function definition:

public class Point1

{

    private int _x ,  _y;    

    public Point1 (Point1 other)

    {

        ...

        ...

    }

//other more constructors here...

}

Answer 1

You can use the below function definition :

public Point1(Point1 other)

{

    _x = other._x ;

    _y = other._y;

}

Also, you can try the below code to pass the arguments:

public class Point2 extends Point1    

{

    private int _z;

    public Point2(Point2 other)

    {

        super(other);

        this._z = other._z;

    }

}

I hope this will help.
