list of objects java code example

Example 1: list in java

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

Example 2: declaration of list in java

ArrayList<String> list=new ArrayList<String>();//Creating arraylist    
      list.add("Mango");//Adding object in arraylist    
      list.add("Apple");    
      list.add("Banana");    
      list.add("Grapes");    
      //Printing the arraylist object   
      System.out.println(list);

Example 3: java list of objects example

List<Object> listAnything = new ArrayList<Object>();
List<String> listWords = new ArrayList<String>();
List<Integer> listNumbers = new ArrayList<Integer>();
List<String> linkedWords = new LinkedList<String>();
