java for i in list code example

Example 1: java loop through arraylist

ArrayList<String> namesList = new ArrayList<String>(Arrays.asList( "alex", "brian", "charles") );
         
for(String name : namesList)
{
    System.out.println(name);
}

Example 2: iterate a list using iterator

Iterator<String> crunchifyIterator = crunchifyList.iterator();
        while (crunchifyIterator.hasNext()) {
            System.out.println(crunchifyIterator.next());
        }

Example 3: traversal of list in java

import java.util.ArrayList;
import java.util.Iterator;

public class IteratorSample {
   public static void main(String[] args) {
      ArrayList<String> list = new ArrayList<String>();
      list.add("JavaFx");
      list.add("Java");
      list.add("WebGL");
      list.add("OpenCV");
      Iterator iterator = list.iterator();
      while(iterator.hasNext()) {
         System.out.println(iterator.next());
      }
   }
}
