Here, we will use while loop and print a number n's table in reverse order. What do you think will happen when it runs? Note that the statement may not be executed even once if the condition is not satisfied when the while statement is reached. The for loop allows you to specify all of the important things about a loop in one place (what value do variables start at, what is the condition to test, and how the loop variables change). Write a C program to print all natural numbers in reverse (from n to 1). It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. The while loop can be thought of as a repeating if statement. while loop works in two steps. Required knowledge - using while loop. int counter = 0; while {counter > 100} if (counter % 2 == 1) cout << counter << " is odd." Do not print the sentinel value. 1.while. Platform to practice programming problems. Written by Nick Parlante. While loop is another loop like for loop but unlike for loop it only checks for one condition. If the Boolean expression is true, the control jumps back up to do statement, and the statements in the loop execute again. Feel free to check that out. The do...while statement creates a loop that executes a specified statement until the test condition evaluates to false. This loop would never end, its an infinite while loop. public class Main { public static void main(String[] args) { for (int i = 0; i = 10; i = i + 2) { System.out.println(i); } } } Java While Loop. We will see the differences soon. Good luck! The while syntax can be written as: while (expression) { statement(s)} The while loop evaluates expression, which must return a boolean value. Solve question related to Java - Loop loop loop. The user can choose to continue answering the question or stop answering it. Similarly, we can use the break statement according to the problem statements. Loops in Java come into use when we need to repeatedly execute a block of statements.. Java while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. While Loop Output - Core Java Questions - while Loop In Java with Example: The Java while loop is Java’s most fundamental looping statement. This is because condition is i>1 which would always be true as we are incrementing the value of i inside while loop. In computer programming, loops are used to repeat a block of code.

Do you want to hear it again? do-while syntax do { // body of the loop } while (condition); Where, condition is some condition that needs to be satisfied to execute the code inside the body of the loop. How many times is any Do-While loop executed? Here, we will use while loop and print a number n's table in reverse order. When condition returns false, the control comes out of loop and jumps to the next statement after while loop. The form of the for loop is Simplicity of while loop exists in its working mechanism. import java.util.Scanner; public class WhileLoopNegativeCondition { public static void main(String[] args) { int counter; Scanner inputDevice = new Scanner(System.in); System.out.print("Please enter loop counter value >> "); counter = inputDevice.nextInt(); System.out.println("Before Loop"); while (counter . Note: The important point to note when using while loop is that we need to use increment or decrement statement inside while loop so that the loop variable gets changed on each iteration, and at some point condition returns false. The while loop loops through a block of code as long as a specified condition is true: Syntax while (condition) { // code block to be executed} In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5: In a Java Do-While loop, the condition is evaluated at the _____ of the statement. Verify that the user enters an even value (use a do loop) do { System.out.print ("Enter an even value:"); value = Keyboard.readInt(); } while (value%2 != 0); 18.
