Suppose there is an array of names and we want to print all the names in that array. Let’s take an example to demonstrate how enhanced for loop can be used to simplify the work. Syntax: for (T element:Collection obj/array) int i 3 int a i++ // a 3, i 4 int b ++a // b. Both increment the number, but ++i increments the number before the current expression is evaluted, whereas i++ increments the number after the expression is evaluated. Note: The object/variable is immutable when enhanced for loop is used i.e it ensures that the values in the array can not be modified, so it can be said as a read-only loop where you can’t update the values as opposed to other loops where values can be modified. i++ and ++i are very similar but not exactly the same. It is inflexible and should be used only when there is a need to iterate through the elements in a sequential manner without knowing the index of the currently processed element. Enhanced for loop provides a simpler way to iterate through the elements of a collection or array. Java For-Each LoopĮnhanced For Loop or Java For-Each loop in Java is another version of for loop introduced in Java 5. To know more about Nested loops refer Nested loops in Java.
