December 2, 2024 - Example 3: We can also loop through an array using while loop. Although there is not much of a difference in for and while loop in this condition. While loop is considered effective when the increment of the value depends upon some of the condition. ... // Java program to iterate over an array // using while loop import java.io.*; class Main { public static void main(String args[]) { // taking an array int a[] = { 1, 2, 3, 4, 5 }; int i = 0; // Iterating over an array // using while loop while (i < a.length) { // accessing each element of array System.out.print(a[i] + " "); i++; } } }

In contrast, Java Lists can grow and shrink over time -- this is a big feature that Lists have that arrays do not. The length of an array can be accessed as a special ".length" attribute. For example, with the above "values" array, we can access the size of the array as "values.length". It is common to use a 0...length-1 for-loop to iterate over all the elements in array:

Iterate through string array in Java - Stack Overflow

You can do an enhanced for loop (for java 5 and higher) for iteration on array's elements:

String[] elements = {"a", "a", "a", "a"};   
for (String s: elements) {           
    //Do your stuff here
    System.out.println(s); 
}

String[] elements = { "a", "a", "a", "a" };

for( int i = 0; i < elements.length - 1; i++)
{
    String element = elements[i];
    String nextElement = elements[i+1];
}

Note that in this case, elements.length is 4, so you want to iterate from [0,2] to get elements 0,1, 1,2 and 2,3.

How to Use a While Loop to Iterate an Array in Java : 9 Steps - Instructables

July 22, 2022 - How to Use a While Loop to Iterate an Array in Java: Today I will be showing you how to use Java to create a While loop that can be used to iterate through a list of numbers or words. This concept is for entry-level programmers and anyone who wants to get a quick brush-up on Java Loops and arrays.

How to loop through an Array in Java? Example Tutorial

The traditional loop uses a counter and allows you to iterate until the last element is reached i.e. counter is equal to the length of the array while enhanced for loop maintains that counter internally, allowing you to iterate without worrying about counts. This results in clean code and also eliminates the possibility of one-off errors. In this article, I'll show you 2 ways to iterate over an array, first by using traditional for loop and second by using enhanced for loop of Java 1.5.

How to loop through an array of different objects in Java using the enhanced for loop - Stack Overflow

Found the answer

public class App {
    public static void main(String[] args) throws Exception {
        Car car = new Car();
        Bicycle bicycle = new Bicycle();
        Van van = new Van();

        Object[] racers = {car, bicycle, van};  

        for(Object x : racers) {
            System.out.println(x.getClass()); 

            ((Vehicle) x).go();  // this is the only change I made
        }
    }
}

The following would have worked

    Vehicle[] racers = {car, bicycle, van};  
    for (Vehicle x : racers) { ... x.go();

Dynamic detection does works too. You could use the modern Stream<?>.

    Object[] racers = {car, bicycle, van};  

    Arrays.stream(racers)
       .filter(r -> r instanceOf(Vehicle)
       .map(Vehicle.class::cast)
       .forEach(r -> {
            r.go(); ...
       };

Java Iteration Tutorial: How to Loop Through an Array in Java - DEV Community

August 15, 2022 - The condition is verified both at startup and at the beginning of each iteration. If this condition is met, the loop body is performed. If it is false, the loop is terminated and the program control is transferred to the line after the loop. To loop through arrayelements, the for-each loop is utilized.
