I have just learned Java after python, How do I print the word 'Red' from this code? and what did I do wrong in this code?

Answer 1

Because color isnt a method, you cant use v1.color("Red") . You have to set it like a normal var using v1.color = "Red" . Then it works fine.

Answer 2

You have to create a setter and getter method like this.

public class Vehicle {
private String color;

public void setColor(String color) {
this.color = color;
}

public String getColor() {
return color;
}
}

Vehicle v = new Vehicle ();

v.setColor("Red");

v.getColor();

And remember variable in class should be always private because of incapsulation.

Lord HN thank you for the answer, I literally copy pasted the code from sololearn and only added the print command, but thank you for straightening things up
