如何获取多行输入

[英]How to take multiple lines of input

If I copy and paste into a program It only takes the first line for instance I copy a few blocks from Microsoft Excel and Paste it pastes the codes like this:如果我复制并粘贴到程序中它只需要第一行,例如我从 Microsoft Excel 复制几个块并粘贴它粘贴这样的代码:

72LYY-785B9-0WQD9
88CXK-4E8BB-TA2GD
JLEIZ-0KYKP-PY2E4
LV5TL-A6CLB-P59GX

My program only takes 72LYY-785B9-0WQD9 , but I want the scanner to take all until it is empty.我的程序只需要72LYY-785B9-0WQD9 ,但我希望扫描仪全部取出,直到它为空。

I am using我在用

String userData = takeInput.nextLine();

I put it into a String and then turn it into an array of chars.我把它变成一个字符串,然后把它变成一个字符数组。
Any help?有什么帮助吗?

Did you try any other approach?你有没有尝试过其他方法?

Scanner stdin = new Scanner(new BufferedInputStream(System.in));
while (stdin.hasNext()) {
  System.out.println(stdin.nextLine());
}
