For-each statement in Java

In Java, the for-each statement allows you to directly loop through each item in an array or ArrayList and perform some action with each item.

When creating a for-each statement, you must include the for keyword and two expressions inside of parentheses, separated by a colon. These include:

  1. The handle for an element we’re currently iterating over.

  2. The source array or ArrayList we’re iterating over.

// array of numbers int[] numbers = {1, 2, 3, 4, 5}; // for-each loop that prints each number in numbers // int num is the handle while numbers is the source array for (int num : numbers) { System.out.println(num); }
