Java Constructors

This lesson is part of Java · All levels

Summary

A constructor is a special method that is automatically called when an object is created with new. The name should be exactly the same as the class name and have no return type. If you don't write constructors at all, Java will provide default constructors without parameters.

Key points

The constructor has the same name as the class and without the return type
The constructor runs automatically when the object is made using new
More than one constructor with different parameters is called a constructor overloading
When there's no constructor, Java creates the default constructor automatically.
