The continue makes it jump to the evaluation at the botton so the program can evaluate if it has to continue with another iteration or exit. In this case it will exit. This is the specification: http://java.sun.com/docs/books/jls/third_edition/html/statements.html#6045 Such language questions you can search it in the Java Language Specification: http://java.sun.com/docs/books/jls/

It seems like scoping would be the issue, what would be the scope of i declared in the while portion of a do while statement? It would seem rather unnatural to have a variable available within the loop when the declaration is actually below the loop itself. You don’t have this issue with the other … Read more
If you’d like to keep value locally scoped for the while loop, you can do this instead: do { Type value(GetCurrentValue()); Process(value); if (! condition(value) ) break; } while(true); This is just personal preference, but I find while loops structured like the following more readable (while instead of do-while): while(true) { Type value(GetCurrentValue()); Process(value); if … Read more
There is no do…while loop because there is no nice way to define one that fits in the statement: indented block pattern used by every other Python compound statement. As such proposals to add such syntax have never reached agreement. Nor is there really any need to have such a construct, not when you can … Read more
You can roll your own looping that’s almost what you want. Here’s an example with loop { code } until { condition } You can’t have a corresponding loop { code } while { condition } because while is a keyword. But you could call it something else. Anyway here’s some rough and ready code … Read more
If you read the comments at top of the file, just below the class declaration, there is a section which explains the use of this construct: Style notes =========== […] There are several occurrences of the unusual “do {} while (!cas…)” which is the simplest way to force an update of a CAS’ed variable. There … Read more
Pretty self explanatory. repeat{ statements… if(condition){ break } } Or something like that I would think. To get the effect of the do while loop, simply check for your condition at the end of the group of statements.
If you always want the loop to execute at least once. It’s not common, but I do use it from time to time. One case where you might want to use it is trying to access a resource that could require a retry, e.g. do { try to access resource… put up message box with … Read more
I am not sure about DO-WHILE IN MS SQL Server 2008 but you can change your WHILE loop logic, so as to USE like DO-WHILE loop. Examples are taken from here: http://blog.sqlauthority.com/2007/10/24/sql-server-simple-example-of-while-loop-with-continue-and-break-keywords/ Example of WHILE Loop DECLARE @intFlag INT SET @intFlag = 1 WHILE (@intFlag <=5) BEGIN PRINT @intFlag SET @intFlag = @intFlag + 1 … Read more
