![]() We shall learn these methods with the help of example Java programs. In this tutorial, we will learn some of the ways to create an infinite for loop. To make the condition always true, there are many ways. The syntax of Java for-each loop consists of data_type with the variable followed by a colon (:), then array or collection. Java Infinite For Loop To make a Java For Loop run indefinitely, the condition in for statement has to be true whenever it is evaluated. It eliminates the possibility of programming errors.Moreover, you cannot traverse the odd or even elements only.īut, it is recommended to use the Java for-each loop for traversing the elements of array and collection because it makes the code readable. The below code is an example of classic for loop : public static void main(String args). Here, you do not have the option to skip any element because it does not work on an index basis. Enhanced for loop(for-each loop and Java 8 lambda expression for loop). The drawback of the enhanced for loop is that it cannot traverse the elements in reverse order. It is known as the for-each loop because it traverses each element one by one. The advantage of the for-each loop is that it eliminates the possibility of bugs and makes the code more readable. It is mainly used to traverse the array or collection elements. Over the period, Java has added different types of for loop. for loop repeatedly loops through the code until a particular condition is satisfied. Before going to each kind of iteration, suppose that we have a List collection as follows: 1. Java for loop and enhanced for loop is a type of control flow statement which provides a compact way to iterate over a range of values. The Java programming language provides four methods for iterating over collections, including for loops, iterator and forEach (since Java 8). It provides an alternative approach to traverse the array or collection in Java. Such kinds of operations are very common in programming. Statement 2 defines the condition for the loop to run (i must be less than 5). ![]() ![]() You can use for each loop in Java to iterate through array, Collections(Set, List) or Map. Statement 1 sets a variable before the loop starts (int i 0). It’s more readable and reduces a chance to get a bug in your loop. It also called: Java for each loop, for in loop, advanced loop, enhanced loop. The Java for-each loop or enhanced for loop is introduced since J2SE 5.0. The basic for loop was enhanced in Java 5 and got a name for each loop. Next → ← prev Java For-each Loop | Enhanced For Loop
