Java Program to Iterate over an ArrayList

Example 1: Iterate through ArrayList using for loop

Output

ArrayList: [Java, JavaScript, Python]
Iterating over ArrayList using for loop:
Java, JavaScript, Python,

In the above example, we have created an arraylist named languages. Here, we have used the for loop to access each element of the arraylist.

Example 2: Iterate through ArrayList using for-each loop

Output

ArrayList: [Java, JavaScript, Python]
Iterating over ArrayList using for-each loop:
Java, JavaScript, Python,

Here, we have used the for-each loop to iterate over the ArrayList and print each element.

Example 3: Iterate over ArrayList using listIterator()

Output

ArrayList: [1, 3, 2]
Iterating over ArrayList:
1, 3, 2,

In the above example, we have used the listIterator() method to iterate over the arraylist. Here,

• hasNext() - returns true if there is next element in the arraylist
• next() - returns the next element of the arraylist

Note: We can also use the ArrayList iterator() method and the ArrayList forEach() method to iterate over the arraylist.
