# What are the differences between constructor and method of a class in Java?

What are the [differences](https://www.mindstick.com/articles/12918/cat-5e-vs-cat-6a-understanding-the-major-differences) between constructor and [method](https://www.mindstick.com/forum/166/webservice-method) of a [class](https://www.mindstick.com/blog/165/generic-class-in-c-sharp) in [Java](https://www.mindstick.com/articles/12214/web-development-company-in-india-laid-on-the-foundation-of-concrete-java-programming)?

| **Constructor** | **Method** |
| --- | --- |
| Constructor is used for initializing the object state. \ \ | Method is used for exposing the object's behavior. |
| Constructor has no return type. Method should have a return type. | Even if it does not return anything, return type is void. |
| Constructor gets invoked implicitly. | Method has to be invoked on the object explicitly. |
| If the constructor is not defined, then a default constructor is provided by the java compiler. | If a method is not defined, then the compiler does not provide it. |
| The constructor name should be equal to the class name. | The name of the method can have any name or have a class name too. |
| Final variable instantiations are possible inside a constructor and the scope of this applies to the whole class and its objects. | A final variable if initialised inside a method ensures that the variable cant be changed only within the scope of that method. |
