We can create an object of the above class Now let us come up with the syntax for the constructor being invoked at the time of object or instance creation. Constructors are called only once at the time of Object creation while method(s) can be called any number of times.Constructors do not return any type while method(s) have the return type or void if does not return any value.Constructors must have the same name as the class within which it is defined while it is not necessary for the method in Java.How Constructors are Different From Methods in Java? It is because java compiler creates a default constructor if your class doesn’t have any. Note: It is not necessary to write a constructor for a class. Every time an object is created using the new() keyword, at least one constructor is called. It is a special type of method which is used to initialize the object.
At the time of calling the constructor, memory for the object is allocated in the memory. It is called when an instance of the class is created. In Java, a constructor is a block of codes similar to the method. It can be used to set initial values for object attributes.
The constructor is called when an object of a class is created. A constructor in Java is a special method that is used to initialize objects. Java constructors or constructors in Java is a terminology been used to construct something in our programs.
