Java for loop tutorial8/9/2023 ![]() ![]() The while statement continues testing the expression and executing its block until the expression evaluates to false. ![]() The while statement or loop continually executes a block of statements while a particular condition is true. } Example to Understand Enhanced for loop in Java: public class EnhancedforloopDemo The syntax to use the enhanced for loop in java is given below.įor(T element : Collection object / array) 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.Īlso, note that the object/variable is immutable when enhanced for loop is used, i.e it ensures that the values in the array cannot 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. Sample Program for For Loop in Java: class ForLoopDemoĮnhanced for loop provides a simpler way to iterate through the elements of a collection or array. And lastly, increment/decrement expression is executed after each iteration through the loop. The termination condition is evaluated in every loop and if it evaluates to false, the loop is terminated. The initialization expression initializes the loop and is executed only once at the beginning when the loop begins. The syntax to use for the loop is given below.įor(initialization condition increment/decrement) A for loop executes a block of code as long as some condition is true. The Java for loop repeats the execution of a set of Java statements. There are three types of looping statements in Java. Looping in programming languages is a feature that facilitates the execution of a set of instructions/functions repeatedly while some condition evaluates to true. Please read our previous article, where we discussed Decision Making Statements in Java with examples. At the end of this article, you will understand what are Looping Statements and their type with examples. In this article, I am going to discuss the Looping Statements in Java with Examples.
