Loop through ArrayList in Java
The elements of the ArrayList can be accessed one by one by using a for loop. A program that demonstrates this is given as follows
Example
import java.util.ArrayList;
import java.util.List;
public class Demo {
public static void main(String[] args) {
ArrayList<String> aList = new ArrayList<String>();
aList.add("Sun");
aList.add("Moon");
aList.add("Star");
aList.add("Planet");
aList.add("Comet");
System.out.println("The ArrayList elements are:");
for (String s : aList) {
System.out.println(s);
}
}
}Output
The output of the above program is as follows
The ArrayList elements are: Sun Moon Star Planet Comet
Now let us understand the above program.
The ArrayList aList is created. Then ArrayList.add() is used to add the elements to this ArrayList. Then the ArrayList elements are displayed using a for loop. A code snippet which demonstrates this is as follows
ArrayList<String> aList = new ArrayList<String>();
aList.add("Sun");
aList.add("Moon");
aList.add("Star");
aList.add("Planet");
aList.add("Comet");
System.out.println("The ArrayList elements are:");
for (String s : aList) {
System.out.println(s);
}
