8/19/2023 0 Comments While loop javaImportant Note: The major difference between While and do While is that statement will be executed atleast once in do while. In do while, we first put statement or code that we want to execute inside the do block and then we put the Boolean expression inside While parenthesis just outside do block. The statements will continue to execute until Boolean expression evaluate to false. So the first iteration of your while loop is working fine. When you call nextInt and nextDouble it will skip any preceding whitespace, however it will not consume any whitespace after. When you call nextLine it will read a whole line, until it encounters or the end of the file. If the condition(s) holds, then the body of the loop is executed after the execution of the loop body condition is tested again. Lets create a simple program to print 1 to 10 number using While loop: public class WhileExample and then evaluate the while Boolean expression. 1 Answer Sorted by: 1 The issue is related to whitespace. increment-decrement-value – increment or decrement the value of initialized variable statement-or-code – The code that you want to execute after Boolean expression evaluate to true. While loop in Java comes into use when we need to repeatedly execute a block of statements. The while loop can be thought of as a repeating if statement. If it comes out to be true then code inside it will executed otherwise compiler jumps outside the loop. Java while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. Boolean-Expression – Boolean expression will be evaluated. Initialize-value – First initialize the value first before starting while loop. While loop is used to iterate a part of the program repeatedly until the specified Boolean condition is true. Statement-or-code //This will be executed continually until Boolean expression evaluate to true The syntax of While in JAVA is: initialize-value
