![]() The forEach() method takes a Consumer functional interface as a parameter, which is used to perform the operation on each element of the Iterable. In the above signature, T represents the type of elements in the Iterable, and action is a Consumer functional interface that accepts a single argument of type T and returns no result. Here is the signature of the forEach() method in the Iterable interface: void forEach(Consumer action) The forEach() method is defined in the Iterable interface in Java. forEach() Signature in Iterable Interface: The body of the lambda expression specifies the operation to be performed on each element. The arrow operator separates the parameter list from the body of the lambda expression. The parameter list specifies the type and name of the parameter passed to the lambda expression. ![]() The syntax for the lambda expression used in the forEach loop consists of the parameter list, the arrow operator ->, and the body of the lambda expression. In this case, the lambda expression simply prints the integer value of each element. The lambda expression (Integer number) -> specifies the operation to be performed on each element of the list. In the above example, the forEach loop is called on the ArrayList “numbers”. Here’s an example of how to use the forEach loop to iterate over an ArrayList of integers and print each element: ArrayList numbers = new ArrayList() ![]() It provides a more concise and expressive way of writing loops as compared to the traditional for loop or the enhanced for loop (for-each loop). Java forEach loop is a feature introduced in Java 8 that allows you to iterate over elements in a collection and perform a certain operation on each element using a lambda expression. ![]()
