java - 无法启动 Activity ，行读取器中的 ArrayIndexOutOfBounds

Question

我不断收到ArrayIndexOutOfBoundsException，但我不确定代码的哪一部分到底导致了此错误。任何帮助将不胜感激。代码是

        while ((line = reader.readLine()) != null) {

            String[] wordOnLine = line.split(",");
            geo.put(wordOnLine[0] , new GeoLocation(wordOnLine[0], Double.parseDouble(wordOnLine[1]), Double.parseDouble(wordOnLine[2]),TimeZone.getTimeZone(wordOnLine[3])));

        }

错误是

Unable to start activity ComponentInfo{swindroid.suntime/swindroid.suntime.ui.Main}: java.lang.ArrayIndexOutOfBoundsException: length=1; index=1
