Loops

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:

The handle for an element we’re currently iterating over.
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);
}
