Java For-Each Loop

Java For-Each Loop (Enhanced `for` Loop)

The for-each loop is used to iterate over arrays or collections in a simpler and more readable way than a traditional for loop.
It eliminates the need for an index variable.

Syntax

item → current element of the array/collection
arrayOrCollection → the array or collection being iterated

Example 1: Iterating Over an Array

📌 Output:

Example 2: Iterating Over Numbers

Example 3: Sum of Array Elements

📌 Output:

Example 4: Iterating Over a Collection (ArrayList)

import java.util.ArrayList;

public class Main {
public static void main(String[] args) {
ArrayList<String> cars = new ArrayList<>();
cars.add("BMW");
cars.add("Audi");
cars.add("Tesla");

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

import java.util.ArrayList;

public class Main {

public static void main(String[] args) {

ArrayList<String> cars = new ArrayList<>();

cars.add("BMW");

cars.add("Audi");

cars.add("Tesla");

for (String car : cars) {

System.out.println(car);

}

📌 Output:

Advantages of For-Each Loop

Readable – no need to manage index variables
Safe – avoids out-of-bounds errors
Quick – easier to iterate over arrays and collections

Limitations

Cannot modify the elements of the array/collection directly
Cannot get the index of the element (use traditional for loop if needed)
