Question
Given the class 'Point' which has two member variables x, and y. Create a new method in the class called "Distance" that returns the Euclidean distance of the point object from the origin (0,0). Choose right method:
1. public double Distance()
{
return Math.sqrt(x*x + y*y);
}
2. public double Distance()
{
return (x*x + y*y);
}
3. public double Distance()
{
return Math.sqrt(x + y);
}
4. public double Distance()
{
return x;
}
1. public double Distance()
{
return Math.sqrt(x*x + y*y);
}
2. public double Distance()
{
return (x*x + y*y);
}
3. public double Distance()
{
return Math.sqrt(x + y);
}
4. public double Distance()
{
return x;
}

option1.
public double Distance()
{
return Math.sqrt(x*x + y*y);
}
