无法实现.请帮助

只有第一个被处理。但是问题是,java不能将它们平等对待。
INFO: [, s, o, n, y]

我的代码如下所示,问题出在哪里?
FileReader fileReader = new FileReader("some_file.txt");
BufferedReader bufferedReader = new BufferedReader(fileReader);
String prevLine = "";
String strLine
while ((strLine = bufferedReader.readLine()) != null) {
logger.info(Arrays.toString(strLine.toCharArray()));
if(strLine.contentEquals(prevLine)){
logger.info("Skipping the duplicate lines " + strLine);
continue;
}
prevLine = strLine;

更新:
似乎在第一行中有一个空格,但实际上没有,并且这种trim
方法对我不起作用。它们不一样:
INFO: [, s, o, n, y]
INFO: [ , s, o, n, y]

我不知道Java添加的第一个Char是什么。
已解决:BalusC的解决方案解决了该问题,感谢您指出了BOM的问题,该问题帮助我快速找到了解决方案。
