Java - Scanner Class - Skipping over the first line when reading a textfile
提问by pingOfDoom
When using a Scanner object to read from a textfile, I want it to skip over the very first line in the file. How would I do achieve this?
当使用 Scanner 对象从文本文件中读取时，我希望它跳过文件中的第一行。我将如何做到这一点？

Just use file.nextLine()before your while loop. This will skip the first line, as explained in the JavaDoc.
只需file.nextLine()在 while 循环之前使用。这将跳过第一行，如JavaDoc中所述。
And a note about your naming. The Java language has widely accepted conventions. Class Names always start with an upper case letter, and variable names always start with a lower case letter (except constants, but don't worry about that now). Read more here.
以及关于您的命名的说明。Java 语言具有广泛接受的约定。类名总是以大写字母开头，变量名总是以小写字母开头（常量除外，但现在不用担心）。在这里阅读更多。

Add the below code before the whileloop to skip the first line.
在while循环之前添加以下代码以跳过第一行。
if(file.hasNext()==true)
{
file.nextLine();
}
else
{
System.out.println("Error: File is empty");
return null;
}
