Java Program To List All Elements In List

Chapter: Miscellaneous Last Updated: 30-04-2023 19:15:30 UTC

Program:

            /* ............... START ............... */
                
import java.util.ArrayList;
import java.util.List;

public class ListElements {
    public static void main(String[] args) {
        List<Integer> myList = new ArrayList<Integer>();
        myList.add(1);
        myList.add(2);
        myList.add(3);
        myList.add(4);
        myList.add(5);

        for (int element : myList) {
            System.out.println(element);
        }
    }
}

                /* ............... END ............... */
        

Output

1
2
3
4
5

Notes:

  • First, the program creates an ArrayList called myList that contains five integers: 1, 2, 3, 4, and 5. The ArrayList class is part of the Java Collections Framework and provides dynamic arrays that can be resized as needed.
  • Next, the program uses a for loop to iterate over each element in myList. The loop declares a variable called element of type int, which will be used to store the value of each element in the list.
  • For each element in the list, the loop assigns its value to the element variable. Then, the println method of the System.out object is called to print the value of element to the console.
  • As a result, when you run the program, you'll see each element in the list printed on a separate line in the console.
  • Note that this program uses the enhanced for loop syntax, which was introduced in Java 5 and makes it easier to iterate over collections such as lists. It's also worth noting that the List interface in Java is a more general interface for lists, but ArrayList is a common implementation of this interface.
