Java Generics Example The Basics Of Java Generics
The java generics programming is introduced in j2se 5 to deal with type safe objects. it makes the code stable by detecting the bugs at compile time. before generics, we can store any type of objects in the collection, i.e., non generic. now generics force the java programmer to store a specific type of objects. The what and why of generics in java. generics is a feature of the java language that promotes type safety, code manageability and efficiency and, most importantly, much cleaner and reduced code. you can use generics to create type safe collections with no boxing and un boxing overhead; this is also known as parametric polymorphism. 5. advanced java (jdbc,servlets,jsp,jstl) for web development. 6. learn java collection framework and generics in simple way [new] free courses: 1. learn java wrapper classes in simple way free course. 2. learn 'this' keyword in java free course. i will focus mainly on . 1. arrays. 2. list and its implementations. 3. iterators cursors in.
