How reference will passed?

Question about the task

Resolved

public class Cat{
private String name;
public void setName(String name){
this.name=name;//set name by passing current reference of object .
}
public String  getName()
return name;//return name or return this.name
//which will correct ?
}

Both will work but I don't understand In return name; how reference passed . Can any one will give brief information?

That's what OOP is all about.

private String name;

is not a varible but a field or attribute of the class Cat. Means, if you create an object, each has its own name field. The scope of the field of course is the entire class, or better, you can access this field in all methods. If you access a field in a method, you can prfix it with this.fieldName. That way you see at once, that it's a field and it won't give problems, if you have parameters with the same name e.g. in the constructor.
