It can be used to replace multiple lines of code with a single line, and is most often used to replace simple if else statements: Syntax variable = (condition) ? The second condition is not even evaluated. Java while loop is another loop control statement that executes a set of statements based on a given condition. The while loop loops through a block of code as long as a specified condition evaluates to true. Usually some execution of the loop will change something that makes the condition evaluate to false and thus the loop ends. If the condition is never met, then the code isn't run at all; the program skips by it. By using our site, you executed at least once, even if the condition is false, because the code block When compared to for loop, while loop does not have any fixed number of iteration.
