1. Syntax The general syntax of a do-while loop is as follows: do { statement(s); } while (condition-expression); Let us note down a few important observations: The do-while statements end with a semicolon. The condition-expression must be a boolean expression. The statement(s) can be...
Here, you are going to learn about while and do...while loops. Java while loop Java while loop is used to run a specific code until a certain condition is met. The syntax of the while loop is: while (testExpression) { // body of loop } Here, A while loop evaluates the text...
循环(loop):一种控制结构,重复执行一组指令。Java提供了3种循环:for 循环、while 循环和 do 循环。 循环控制变量(loop control variable):for 循环中的变量,每次执行 for 循环时都会修改循环变量值,通过检查该变量决定是否结束循环。 机器语言(machine language):由计算机能够直接执行的指令组成的编程语言。机器语言...
The while loop loops through a block of code as long as a specified condition is true:SyntaxGet your own Java Server 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 ...

Loops are the way to do this. A while loop has a boolean test and a body containing statements, like this: int count = 0; while (count < 100) { // test: boolean test within (..) System.out.println("count:" + count); // body: statements within {..} count = count + 1;...

If the value of the condition is true, the loop executes; if it is false, the loop exits. The loop executes repeatedly until the test condition becomes false. Example 1.13 “Do ... While” Loop do{ [Statement Block]; } while( condition ); In a Do... While loop, the test ...
You’ll get the full loop scoop later in the book, but not for awhile, so let’s do while for now. The syntax (not to mention logic) is so simple you’re probably asleep already. As long as some condition is true, you do everything inside the loop block. The loop block is ...
6.The do loop differs from the while loop in that A the while loop will always execute the body of the loop at least once B the do loop will always execute the body of the loop at least once C the do loop will continue to loop while condition in the while statement is false and ...
