Java Arrays Loop: Efficiently Looping Through Arrays Using For Loops

Learn how to loop through array elements in Java using the for loop. Discover how the length property helps in determining the number of iterations to efficiently process arrays in your Java programs.

Java Arrays Loop

Loop Through an Array

You can loop through the array elements with the for loop, using the length property to specify the number of iterations.

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
for (int i = 0; i < cars.length; i++) {
System.out.println(cars[i]);
}
    

Volvo
BMW
Ford
Mazda
    

Loop Through an Array with For-Each

The "for-each" loop is used to loop through elements in arrays:

for (type variable : arrayname) {
// code block to be executed
}
    

The example below outputs all elements in the cars array using a "for-each" loop:

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
for (String i : cars) {
System.out.println(i);
}
    

Volvo
BMW
Ford
Mazda
    

The "for-each" loop is easier to write, does not require a counter, and is more readable compared to the traditional for loop.
