[Java] Traversing a Java collection : For vs Foreach vs Stream Foreach vs Stream ForeachOrdered

First We create a list of String objects,

List<String> list = new ArrayList<>();

list.add("DEF");
list.add("ABC");
list.add("GHI");
     

For Loop

 for(int i=0; i < list.size() ; i++){
    System.out.println( list.get(i) );
 }

For Each 

for(String value : list){
    System.out.println( value );
}

Stream ForEach

list.stream().forEach(System.out::println);

Stream ForEachOrdered

list.stream().forEachOrdered(System.out::println);


Note : All of these traversing is not Null safe, NullPointerException would be thrown if the list in Null.
