A nested while loop is a while statement inside another while statement. In a nested while loop, one iteration of the outer loop is first executed, after which the inner loop is executed. The execution of the inner loop continues till the condition described in the inner loop is satisfied.

How do-while loop works? First, the statements inside loop execute and then the condition gets evaluated, if the condition returns true then the control gets transferred to the “do” else it jumps to the next statement after do-while.

Contrast with the while loop, which tests the condition before the code within the block is executed, the do-while loop is an exit-condition loop. This means that the code must always be executed first and then the expression or test condition is evaluated. If it is true, the code executes the body of the loop again.

do { statement(s); } while( condition ); Notice that the conditional expression appears at the end of the loop, so the statement(s) in the loop executes once before the condition is tested. If the condition is true, the flow of control jumps back up to do, and the statement(s) in the loop executes again.

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. The while loop can be thought of as a repeating if statement.

A great use for the Do-While loop is the menu: The menu is displayed continuously until the end user picks a value. If they type a certain menu item, then the code stops. While the example below may look complicated, pay close attention to the beginning and end of the code: Remember the condition is checked at the end!

C – do while loop in C programming with example. ... A do while loop is similar to while loop with one exception that it executes the statements inside the body of do-while before checking the condition. On the other hand in the while loop, first the condition is checked and then the statements in while loop are executed.

In this tutorial we will discuss do-while loop in java. do-while loop is similar to while loop, however there is a difference between them: In while loop, condition is evaluated before the execution of loop's body but in do-while loop condition is evaluated after the execution of loop's body.

DO loop executes the block of statements until the number of times specified. DO loop is an unconditional looping statement. No logical expression or condition used in DO loop. The block of statements can be executed number of times specified in DO loop.

A similar condition-controlled loop is a DO WHILE loop. ... With the WHILE loop the condition is checked at the beginning, and, with count > 4, the code is not executed and nothing is output. With the DO WHILE loop, we would get an output of 4 because the condition is checked after the print statement is executed.
