In the preceding code, the while loop checks the condition
(i <= 10) that evaluates to true. The statements written inside the
body of the while loop get executed. The value of the variable i
will be incremented by 1 (i++). The loop checks the condition
again and again until the value of the variable i becomes more
than 10. This variable is also called a control variable. The control
variable defines the duration until which the loop will execute.
The do-while Loop
Start
The do-while loop is similar to the while loop. The only
difference is that the do-while loop will execute the statements
written inside its body at least once, whether the given do...while Loop Body
condition returns true or false. The do-while loop executes the
statements written inside its body and checks the condition.
If the condition evaluates to true, the loop will execute again
True Conditional
and again until the given condition becomes false.
Expression
The syntax of the while loop is as follows:
do
False
{
Stop
[statements]
Flowchart of do-while loop
[increment/decrement expression]
}
while(< conditional expression >);
For example,
public class DoWhileLoop
{
public static void main(String args[])
{
int i = 1;
do
