在bluej中获得“非法表达式开始”错误

问题描述：

我对上述问题持续发生错误。请帮助..... 我必须在下周五之前将此代码作为我项目的一部分提交。我在网上看过其他程序，但都使用缓冲区读取器，所以我不能理解。在bluej中获得“非法表达式开始”错误

@Simze为什么？这很好。问题是最后一个方法最后的return语句。 – f1sh

@Ansh你的方法''体育''有返回类型的void，这意味着你不能返回任何东西。然而，这就是你在这里尝试的：''返回String {word，clue};''。这个陈述也不是一个有效的表达。 – f1sh

对不起我的坏！已删除评论 –

答

请更改功能

void sports() { 

    // Code 

     return String {word,clue}; 
    }

要：

String[] sports() { 

     // Code 
     return new String[]{word, clue}; 
    }

这意味着你只需要改变的功能运动的返回类型，并返回一个有效的对象。
