In this tutorial, we will learn how to use while and do while loop in Java with the help of examples.

Loops can execute a block of code as long as a specified condition is true. Loops are handy because they save time, reduce errors, and they make code more readable. The while loop repeats a block of code as long as the specified condition is true:

September 28, 2023 - Below are some examples where a while loop can be applied. ... Write a program that will take in a start number and an end number from a user. Then, using a while loop show all the values from the start to the end number, (inclusive).

October 7, 2024 - import java.util.Scanner; public class ReadSetIntegers { public static void main(String[] args) { Scanner console = new Scanner(System.in); int number; char choice; int evenSum = 0; int oddSum = 0; do { System.out.print("Enter the number "); number = console.nextInt(); if( number % 2 == 0) { evenSum += number; } else { oddSum += number; } System.out.print("Do you want to continue y/n? "); choice = console.next().charAt(0); }while(choice=='y' || choice == 'Y'); System.out.println("Sum of even numbers: " + evenSum); System.out.println("Sum of odd numbers: " + oddSum); } }

56. Write Java program to Implement infinite loop using do-while loop View Solution

Execute the body statements, starting at the top and proceeding down through them all. Go back to step 1 and check the test again. If it is true, run the body again. Each time the body finishes, "loop around" and check the test again. Each run of the body is called an "iteration" of the loop. Eventually the test is false, the loop exits, and the program continues with the line after the while-loop.

int count = 1; while (count <= 10) { count *= 2; } count = count - 10; ... Count is changed inside the loop and after the loop. ... Count is changed inside the loop and after the loop. ... Don't forget to subtract 10 from count after the loop.

If the test expression is false the first time the while expression is checked, the loop body will be skipped and the program will begin executing at the first statement after the while loop.Let’s take an example to understand this. In below program user enters the value of loop counter variable, If counter variable is less than 5, then the loop will execute and increment the counter variable by one till counter value is equal to 5. If counter variable is more than or equal to 5, the loop will not execute. ... import java.util.Scanner; public class WhileLoopNegativeCondition { public static

In this tutorial we will learn about do while loop in Java programming language.

I completed one of the JAVA exercises on w3schools.com

September 6, 2025 - The process repeats from step 2. But if the condition evaluates to be 'False', the loop will immediately terminate and the program will carry on with the next statement just after the do...while loop. Loop Termination In this way, the loop will continue repeating execution of the loop body until the condition is true. Once it becomes false, the loop will terminate.

February 26, 2026 - So you got an idea about the java do while basics , here we share 7 unique examples with outputs do check it out. Example Program – 1 ( Executing without checking condition for the first time ) ... In the above sample example, value of a is 1 by the time the control comes into the do while loop.

February 22, 2016 - Whereas the while loop contains the condition and the body, the for loop has two additional · parts called the initialization and increment. The form of the for loop is ... You can initialize and increment more than one loop variable, as shown in the following. ... This loop starts by setting n to 0.

To demonstrate a practical example of the while loop combined with an if else statement, let's say we play a game of Yatzy:
