A method must be declared within a class. It is defined with the name of the method, followed by parentheses ().
JAVA (static) method can be accessed without creating an object of the class or it can be accessed by creating objects using the corresponding class.
A constructor in Java is a special method that is used to initialize objects. Java constructor is invoked at the time of object creation. It constructs the values for the object that is why it is known as constructor.

Explanation:
Java methods are an essential part of object-oriented programming in Java. They are used to perform certain actions or tasks, and they can also return values. Let's analyze each statement given in the question to understand why the correct answer is option 'D'.
Statement a: Java methods are declared within the class.
Methods in Java are defined within a class. They are enclosed within the curly braces of a class definition. By declaring methods within a class, we can encapsulate code and organize it into reusable blocks. Methods can be declared with or without parameters, and they can have a return type or be void (i.e., not returning any value).
Statement b: Methods are accessed by creating objects using the corresponding class.
To access a method in Java, we usually create an object of the class that contains the method. By creating an object, we can invoke or call the method using the object's reference. This allows us to utilize the functionality provided by the method.
Statement c: Constructors are a special type of methods.
Constructors in Java are special methods that are used to initialize objects of a class. They have the same name as the class and do not have a return type, not even void. Constructors are automatically called when an object is created, and they are responsible for initializing the object's state. While constructors share some similarities with methods, such as having parameters and being declared within a class, they have a unique purpose of object initialization.
Conclusion:
All three statements are true about Java methods. Methods are declared within the class, they are accessed by creating objects of the corresponding class, and constructors are a special type of methods used for object initialization. Therefore, the correct answer is option 'D' - All of the above.
