Java - Classes and Objects

Given the class Movie, which constructor correctly initializes the instance variables title and director for each object?

Apublic void Movie(String title, String director) { this.title = title; this.director = director; }

Bpublic Movie(String t, String d) { title = t; director = d; }

Cpublic Movie() { title = ""; director = ""; }

Dpublic Movie(String title, String director) { this.title = title; this.director = director; }

Step-by-Step Solution

Solution:

Step 1: Identify correct constructor syntax
A constructor must have no return type and the same name as the class.
Step 2: Analyze options
public Movie(String title, String director) { this.title = title; this.director = director; } correctly uses this to assign parameters to instance variables.
public Movie(String t, String d) { title = t; director = d; } assigns without this, which works only if parameter names differ.
public Movie() { title = ""; director = ""; } is a default constructor, not initializing variables from parameters.
public void Movie(String title, String director) { this.title = title; this.director = director; } has a return type void, so it's a method, not a constructor.
Final Answer:
public Movie(String title, String director) { this.title = title; this.director = director; } correctly initializes instance variables.
Quick Check:
Constructor name matches class and no return type [OK]
