Display each list element in a separate line (console)

Question

In this part of code:

    System.out.println(\"Alunos aprovados:\");
    String[] aprovados = {\"d\", \"a\", \"c\", \"b\"};
    List list = new         


        

Answer 1

Iterate through the elements, printing each one individually.

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

Alternatively, Java 8 syntax offers a nice shorthand to do the same thing with a method reference

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

or a lambda

list.forEach(t -> System.out.println(t));

Answer 2

If one wants to display each element in the same line, without those brackets:

public static void main(String[] args) {
    Set<String> stringSet = new LinkedHashSet<>();
    stringSet.add("1");
    stringSet.add("2");
    stringSet.add("3");
    stringSet.add("4");
    stringSet.add("5");
    int i = 0;
    for (String value : stringSet) {
        if (i < stringSet.size()-1) {
            System.out.print(value + ",");
        } else {
            System.out.print(value);
        }
        i++;
    }
}
