iterate list in java code example

Example 1: java loop through arraylist

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

Example 2: java loop through list

for (E element : list) {
    . . .
}

Example 3: java iterate over list

for (int i = 0; i < crunchifyList.size(); i++) {
            System.out.println(crunchifyList.get(i));
        }

Example 4: iterate through an arraylist java

// will iterate through each index of the array list
// using the size of the array list as the max.
// (the last index is the size of the array list - 1)

for (int i = 0; i < myArrayList.size(); i++) {
  
  System.out.println(myArrayList.get(i));
  // will print each index as it loops
}

Example 5: iterate list in java

Iterator itr=list.iterator();
while(itr.hasNext)
{
 system.out.println(itr.next); 
}

Example 6: traversal of list in java

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

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