Print an ArrayList with a for-each loop

Question

Given the following exists in a class, how do I write a for-each that prints each item in the list?

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

I have:

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

Solution 1

Your code works. If you don't have any output, you may have "forgotten" to add some values to the list:

// add values
list.add("one");
list.add("two");

// your code
for (String object: list) {
    System.out.println(object);
}

Solution 2

import java.util.ArrayList;
import java.util.List;

class ArrLst{

    public static void main(String args[]){

        List l=new ArrayList();
        l.add(10);
        l.add(11);
        l.add(12);
        l.add(13);
        l.add(14);
        l.forEach((a)->System.out.println(a));
    }
}
