此代码显示错误。此代码有什么问题？

Question

File file = new File("D:/projects/tFile.txt") ;
        file.createNewFile();  //Unhandled exception type IOException
        FileOutputStream fout = new FileOutputStream(file); //Unhandled exception type FileNotFoundException
        String s = "Cricket";
        byte []b = s.getBytes();
        fout.write(b);//Unhandled exception type IOException
        fout.close();// Unhandled exception type IOException

这显示了FileNotFound Exception和IoException。

Answer 1

它要求您处理从您使用的方法抛出的异常。

将它们包围在try catch块中。

public void method(){
        try {
            File file = new File("D:/projects/tFile.txt") ;
            file.createNewFile();
            FileOutputStream fout = new FileOutputStream(file);
            String s = "IPL is very entertaining tournament";
            byte []b = s.getBytes();
            fout.write(b);;
            fout.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

执行得很好。可能是你D：/项目丢失了。 或者可能是由于例外

public static void main(String[] args) throws IOException {
    File file = new File("D:/Test/tFile.txt") ;
    file.createNewFile();
    FileOutputStream fout = new FileOutputStream(file);
    String s = "IPL is very entertaining tournament";
    byte []b = s.getBytes();
    fout.write(b);;
    fout.close();
}
