我一直在爲這個學校的代碼工作,但我一直在得到一些錯誤,我不能fix.can有人幫助我!!!!。代碼所做的是用戶在文本框中輸入數字1 2 3或4,Applet將爲每個數字繪製不同的形狀。如何解決這些「非法表達式」錯誤?
the errors

這不是如何在SO上提出問題,這就是爲什麼你的問題即將被關閉爲「不是真正的問題」。請閱讀http://stackoverflow.com/questions/how-to-ask。 – 2011-03-31 18:00:54
這不是很具體,吉姆。我實際上認爲他很好地識別了他收到的錯誤,並標記了錯誤所在的代碼行號。當你關閉它時,我正在做一個很好的答案。太糟糕了,我無法幫助這個人。我正在提名重新開放。 – 2011-03-31 18:03:54
如果你已經關閉它作爲這個問題的重複,我可能已經瞭解:http://stackoverflow.com/questions/1534263/how-doi-i-fix-an-illegal-start-of-expression-error-在Java的 – 2011-03-31 18:08:31
