This tutorial is all about Double Brace Initialization in Java for List Collection

. In this tutorial you will learn How to use Double Brace Initialization in Java for List Collection. List Collection is very useful when you want to store a lot of data in a single array or datatype. it help you organize your data and allow you to call then easily just by accessing its index

. basically, a list collection stores elements by insertion order (either at the end or at a specific position in the list). A list maintains indices of its elements so it allows adding, retrieving, modifying, removing elements by an integer index (zero-based index; the first element is at 0-index, the second at 1-index, the third at 2-index, and so on). The following picture illustrates a list that stores some String elements. follow all the steps below to complete this tutorial.
