loop in java 8
List<Integer> data = new ArrayList<>();
//Indexed Loop
for(int i = 0,size=data.size();i<size;i++){
System.out.println(data.get(i));
}
//For each loop
for(Integer element : data){
System.out.println(element);
}
//Using forEach
data.forEach(System.out::println);
//Using Stream
data.stream().forEach(System.out::println)
//While loop
int i = 0;
while(i<data.size()){
System.out.println(data.get(i++));
}
