can i get help with this java question please

A Box class Consider the class public class Box extends Objectf private String stuff: Constructors Write two constructors for the class. The first constructor will take zero input arguments and set the stuff attribute to null. The second will take a String as input and set the stuff attribute to input string Getter and Setter Write a public getter method called getStuff that returns the string stored by the stuff attribute. If stuff is null, it should return the string "no stuff in here". Write a public setter method called setStuff that takes a string as input. If the stuff attribute is currently null, the method sets it to the input string. If stuff is not null, then it replaces its value with the concatenation of the input string with the character "" and then with the current string in stuff. For example, Box b = new Box(); // stuff is null b.getstuff b.setStuff ("cat"); // stuff is "cat" b.setstuff ("dog"): // stuff is "doglcat" // returns "no stuff in here
