how list work in java code example

Example 1: how to make java list

//Creating arraylist example 
ArrayList<String> list = new ArrayList<String>();  
 
//Adding objects in arraylist 
list.add("Mango");    
list.add("Banana");   

//Change the element (index,"new value")
list.set(1,"Dates");

LIST: Can store duplicate values,
      Keeps the insertion order. 
      It allows multiple null values, 
      Also we can read a certain value by index.
- ArrayList not syncronized, array based class 
- LinkedList not synchronized, doubly linked
- Vector is synchronized, thread safe
