Generics from Java

Java Generic methods and generic classes allow programmers to define a collection of similar types, with a single method statement, a set of related methods, or with a single class statement, respectively. Generics also provide protection of compile-time sort that helps programmers at compile time to capture invalid forms. Using Java Generics, this guide will take you through simple and functional ways.

To work with type-safe objects, Java Generics programming is implemented in J2SE 5. By detecting the bugs at compile time, it renders the code stable.

If we could write a single sort method that could sort the elements in an Integer array, a String array, or some sort of array that supports sorting, it would be good.

Java Generic methods and generic classes allow programmers to define a collection of similar types, with a single method statement, a set of related methods, or with a single class statement, respectively.

Generics also provide protection of compile-time sort that helps programmers at compile time to capture invalid forms.
We might write a generic method for sorting an array of objects using the Java Generic principle, then invoke the generic method to sort the array elements with Integer arrays, Double arrays, String arrays, and so on.
