java list set method code example

Example 1: set method in listiterator in java

import java.util.ArrayList;
import java.util.ListIterator;

public class Main {


    public static void main(String[] args) {
        ArrayList days = new ArrayList<>();

        days.add("Sun");
        days.add("Mon");
        days.add("Tue");
        days.add("Thu");
        days.add("Fri");
        days.add("Sat");

        ListIterator iterator = days.listIterator();

        while (iterator.hasNext()) {
            System.out.println(iterator.next());
        }

        iterator.set("None");

        System.out.println("After set : ");

        for (String item : days) {
            System.out.println(item);
        }
    }

}

Example 2: java set value of arraylist

import java.util.ArrayList;

public class SetExample {
  public static void main(String args[]) {
    ArrayList<Integer> arraylist = new ArrayList<Integer>();
    arraylist.add(1);
    System.out.println(arrayList.get(0));
    //1
	arrayList.set(0, 2)
    System.out.println(arrayList.get(0));
    //2
  }
}

Example 3: .set arraylist

Java arraylist set()
