Continue instruction of while loop not executed

Question

A continue instruction in a while loop is not executed. In Eclipse Debugging, the loop just breaks after the System.out.

Anyone know what may cause this, is there a way to debug on cpu instruction level to see what happens ?

  do { // recursive calls through element.parents() until the formula pattern (patternFormula) matches
                counter++;
                System.out.println(counter);
                lookupElement = lookupElement.parent();

                String s = replaceArrowTagAndClean(lookupElement.html()); // replace <img .. src=> and return text()

                m = patternFormula.matcher(s);
                if( (found = m.find()) ) {
                    oneMoreLookahead = false;
                    System.out.println("Continue " + counter);
                    continue;
                }
            } while(!found || oneMoreLookahead);

            System.out.println("End");

Output is:
1
2
3
4
Continue 4
End

(Sry, had quite some trouble creating this post. lol)

Post code itself, not image of code. Do you expect us to rewrite it to test it out? — Amongalen

neither of your conditions in your while loop hold true at that point. Why should continue; change that? — XtremeBaumer

What is your expected result? Why do you think it should behave that way? — Amongalen

The instruction continue will skip all the following lines of code in the loop and will go to the next iteration.

If you place the continue as the last line of code of the loop the behaviour leaving that instruction or removing it is the same.

In your case you can simply use the break instruction to exit the loop immediately.

I mistakenly thought the continue would jump to the start of the loop (behind the do { ) and skip the while condition: while(!found || oneMoreLookahead). That is not the case, thanks for help. (Clarification)
