java中FileOututStream文件字节输出流对象的创建

Question

在创建FileOututStream文件字节输出流对象时，显示我传入的参数不正确，不明白我错在哪了

public class FileOutputStream {
    public static void main(String[] args) {
        FileOutputStream fileOutputStream = new FileOutputStream("d:\\a.txt");

    }
}

Answer 1

应该是需要抛异常 throws FileNotFoundException

 public static void main(String[] args) throws FileNotFoundException {
        FileOutputStream fileOutputStream = new FileOutputStream("d:\\a.txt");
    }
