Java For-Each Loop

The for-each loop is a simplified version of the for loop that is specifically designed to iterate over elements in an array or any other collection of data.

Syntax

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

for (type variableName : arrayName) {

  // code block to be executed

}

Example

The following example demonstrates how to print all elements in a cars array using a for-each loop:

String[] vehicles = {"Honda", "Toyota", "Chevrolet", "Mazda"};
for (String car : vehicles) {
  System.out.println(car);
}

String[] vehicles = {"Honda", "Toyota", "Chevrolet", "Mazda"};

for (String car : vehicles) {

  System.out.println(car);

}

In this example, the for-each loop iterates through each element in the vehicles array and prints it.

Key Points

• The for-each loop is ideal for looping through arrays and collections as it simplifies code and reduces the chance of errors.
• It is particularly useful when you don’t need to access the index of the elements, but just need to process each element directly.
