Modeling complex entities involves defining and invoking methods and constructors. Furthermore, defining robust and reusable code requires learning important mechanisms for code re-uses, such as constructor chaining and method overloading. Use this course to delve into these important techniques that are required to write clean and maintainable Java code. Learn how to define methods with the same name but different signatures (i.e., different order and type of input arguments), invoke overloaded methods, and add constructors to a class. This course will also enable you to use the 'this' keyword to invoke multiple constructors, also known as constructor chaining. By the time you are done with this course, you will have the skills to use important code re-use mechanisms such as method overloading and constructor chaining in java.
