> **"Generics allow the reusability of code, where one single method can be used for different `data-types` of variables or objects."**


The idea is to allow different types like `Integer`, `String`, … etc and user-defined types to be a parameter to methods, classes, and interfaces. 

*For example,* classes like `HashSet`, `ArrayList`, `HashMap`, etc use generics very well. We can use them for any type.


The following example illustrates three **non-generic** (type-sensitive) functions for finding maximum out of 3 inputs:




In this lesson, an explanation is provided to get started with Generics Methods (functions) in Java.
