}print arraylist java
Arrays.toString(list.toArray())printing arraylist
for(int name: arraylist)

}print the list in java
List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6);
//method 1 : Conventional way of printing arraylist
for (int number : numbers) {
System.out.print(number+ ); //Output: 1 2 3 4 5 6
}
//method 2 : Lambda Expression to print arraylist
numbers.forEach(value -> System.out.print(value+ " ")); //Output: 1 2 3 4 5 6
//method 3 : Lambda Expression (method reference) to print arraylist
numbers.forEach(System.out::print); //Output: 123456Copyright © 2021 Codeinu
