Java while loop start by verifying the condition if it is true the code within the while loop will run.

While loop flowchart java. 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. So java do while loop executes the statements inside the code block at least once even if the given condition fails. 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 java while loop is to iterate a code block for a given number of times till the condition inside a loop is false.

The java do while loop will test the given condition at the end of the loop. In the above syntax the test expression inside parenthesis is a boolean expression. Generation of while loops in flowchart code if an action or decision node has an exit transition with a guard as well as a second exit transition and there is also a transition that brings the flow back to the original decision point ibm rational rhapsody recognizes that these elements represent a while loop and generates the appropriate code. The do while loop is a variant of the while loop.

If the test expression is evaluated to true statements inside the while loop are executed. If the condition is false the java while loop will not run at least once. The while loop tests the condition before entering into the code block. If test condition is false the control exits do while loop and next section of code gets executed.

That means body of the do while loop will be executed once before any test condition is tested. So for having a loop which we think that it must execute body at least once we use do while loop.
