Programmers makes mistake. If theconditional-expressiongiven in while loop never terminatesthen the loop will result in an infinitewhile-loop. For example, in the previous program, if theindexvalue is not incremented after each iteration, then the condition will never terminate. In the next example...
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 ...
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 textExpression inside the parenthesis (). If the textExpression evaluates to true, the code ...
while loop do...while loop In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do..while loop. while loop The syntax of the while loop is: while (testExpression) { // the body of the loop } How while loop works? The while loop ev...
Syntax Below is the general code for creating a while loop. The while loop first checks the condition, and then decides what to do. If the condition proves to be false, the instructions in the code block will not be executed. while (condition) { //Instructions be executed } Example A ...
Syntax while (condition) { // Code to be executed } Powered By condition: A boolean expression evaluated before each iteration. If true, the loop body is executed; if false, the loop terminates. Examples Example 1: Basic while Loop public class WhileExample { public static void main(Stri...
Syntax do{ // code block to be executed } while(condition); Example The example below uses ado whileloop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested: ...
While-loop是一种常见的编程语言结构,用于重复执行一段代码,直到指定的条件不再满足为止。它的语法通常由一个循环条件和一个代码块组成。 循环条件是一个布尔表达式,用于判断是否继续执行循环。如果循环条件为真(true),则代码块会被执行;如果循环条件为假(false),则循环结束,程序会继续执行循环之后的代码。 以下是一...
