In this example, we’ll learn how to get size or number of elements currently stored in ArrayList. We will also see how to loop through element of the ArrayList.
Source Code
package com.beginner.examples;
import java.util.ArrayList;
public class GetNumberArrayListIterateExample {
public static void main(String[] args) {
ArrayList al = new ArrayList();
al.add("a");
al.add("b");
al.add("c");
al.add("d");
for (int i = 0; i < al.size(); i++) {
// Gets the element of the specified index
String element = al.get(i);
System.out.println(element);
}
}
}
Output:
a
b
c
d
