Constructor with paremeter of the same name?

That's not the same name, that's the same type. So if we have "Auto y", Auto is the type and y is the name of the parameter. Anyway, these constructors are generally used to make a copy of that other object. It simply sets its own variables to the values of the variables in the other Auto object.

So for example:

public class Auto {

private int wheels;

public Auto(int wheels) {

this.wheels = wheels;

}

public Auto(Auto y) {

this.wheels = y.getWheels();

}

public int getWheels() {

return wheels;

}

}

Now I can do:

Auto firstAuto = new Auto(4);

Auto secondAuto = new Auto(firstAuto);

// both of them have 4 wheels
