A break problem in java.

Question

I am making a geography quiz, where a user can choose from 3 different quizzes: either plate tectonics, rivers or rocks. i have saved the questions in a textfile and their related answers in an array. In my quiz i have a set of questions, and i have done a count down timer, so that the questions should be answered within a specific amount of time. If the user doesn't answer the questions within the specified time, it issues a message saying "time over". My problem is that after it displays the message "time over" it continues to display the questions, and so the user can continue answer them, and this is a bit ridiculous. Even though i used a "break" its still not exiting the loop. To work in a good way, it should stop asking questions, and display the result. Can someone pls help me figure out my mistake? Thanks a lot for the help. :-)

From the language specification:
http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.26
At run time, the result of the assignment expression is the value of the variable after the assignment has occurred. The result of an assignment expression is not itself a variable.
In your code, you have an assignment, not a comparison in your if condition:
            else if(timeForMore=false)When the else if condition is evaluated, timeForMore gets set to false, but then the else if block doesn't evaluate, because the condition's value was false. So the break statement is always skipped. Make it a comparison with == and it will work the way you expect.
