我正在尝试从class
实现HighestScoreFile.java
,并且在编译时出现此错误:
...MemoryGame.java:211: error: unreported exception IOException; must be caught or declared to be thrown
HighestScoreFile.HighestScoreFile(input, hours, minutes, seconds, click);
^
1 error
在实现此
HighestScoreFile.java
之前,我已经使用main
类进行了测试public static void main(String[] args) throws IOException
{
HighestScoreFile("abcdefg", 12, 13, 14, 30);
}
HighestScoreFile.java
用于将数据保存到Highest.txt
。但是,当我使用下面的代码实现另一个
.java
时,它将显示该错误。HighestScoreFile.HighestScoreFile(input, hours, minutes, seconds, click);
我该如何解决这个问题?
最佳答案
您需要将异常抛出到方法之外:
public void someMethod() throws IOException
{
// ...
HighestScoreFile.HighestScoreFile(input, hours, minutes, seconds, click);
// ..
}
或赶上兴奋:
try
{
HighestScoreFile.HighestScoreFile(input, hours, minutes, seconds, click);
}
catch (IOException ex)
{
// handle the exception
}
我建议您遵循Java exception trail。
