Within a method, we can alter the flow of control using either conditionals or loops. The loop statements while, do-while, and for. allow us execute a statement(s) over and over. Like a conditional, a loop is controlled by a boolean expression that determines how many times the statement is executed. E.g.,
22 mar 2023 · Java do-while loop is an Exit control loop. Therefore, unlike for or while loop, a do-while check for the condition after executing the statements of the loop body. Syntax: do. { // Loop Body. Update_expression. } // Condition check. while (test_expression);
The do-while loop is like saying, "Take a turn, and keep doing it until you win." It ensures you get to play at least once. It's syntax is as follows: do { //code to be executed } while (condition); The do-while loop executes the code first time irrespective of condition met or not and then checks the condition.
The do-while Loop • A do-while loop looks like this: • statement is executed once initially, guaranteed to run at least once, and then the condition is evaluated • statement is executed repeatedly until condition becomes false do {statement;} while ( condition);
The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.
The do -while Loop • The do -while loop is a post-test loop, which means it will execute the loop prior to testing the condition. • The do -while loop (sometimes called called a do loop) takes the form: do {statement(s);}while ( condition ); • Example: TestAverage1.java
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 inside the while loop is executed.
