![]() ![]() With an enhanced for loop there is no danger an index will go out of bounds. (The foreach loop statement is unique because this is the only place in Java where a colon is used.) After the colon is a collection of values, such as an array. The colon is used as a shortcut for the foreach operation. It is also called an exit-controlled loop. Then, you define a temporary variable int x, followed by a colon. In a dowhile loop, the condition is always executed after the body of a loop. If a condition is true then and only then the body of a loop is executed. Therefore, when reading each element, one by one and in order, a for-each should always be chosen over an iterator, as it is more convenient and concise. accesses the String references in names and assigns them to nm. In while loop, a condition is evaluated before processing a body of the loop. ![]() A for loop is a repetition control structure that allows you to efficiently write a loop that needs to be executed a specific number of times.Ī for loop is useful when you know how many times a task is to be repeated. The for-each loop, added in Java 5 (also called the 'enhanced for loop'), is equivalent to using a -it's syntactic sugar for the same thing.
