For-Each Loop

The for-each Loop

There is also a "for-each" loop, which is used exclusively to loop through elements in an array (or other data structures):

Syntax

for (type variableName : arrayName) {
  // code block to be executed
}

The for-each loop is simpler and more readable than a regular for loop, since you don't need a counter (like i < array.length).

The following example prints all elements in the cars array:

Example

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};

for (String car : cars) {
  System.out.println(car);
}

Here is a similar example with numbers. We create an array of integers and use a for-each loop to print each value:

Example

int[] numbers = {10, 20, 30, 40};

for (int num : numbers) {
  System.out.println(num);
}

Note: Don't worry if you don't fully understand arrays yet. You will learn more about them in the Java Arrays chapter.
