如何通过Java中的命令行获取输入？ [英] How to get input via command line in Java?

问题描述

我目前有这个代码需要用户输入伪ify发送一些单词并在稍后对整数提交模糊处理。我只需要获得用户输入。任何人都有一个很好的api源来得到这个？我想我应该寻找系统。命令。

I currently have this code that needs user input to pseudo-ify some words to send out and commit obfuscation on the integer later. I just need to get the user input. Anyone have a good source of api to get this from? I think I should be looking for System. commands.

推荐答案

Scanner 类在Java 5.0中实现，使输入更容易：

The Scanner class was implemented in Java 5.0 to make getting input easier:

扫描仪输入=新扫描仪（System.in） System.in 将允许控制台输入。

Scanner input = new Scanner(System.in) the System.in will allow for console input.

Scanner sc = new Scanner(System.in);
int i = sc.nextInt();
/* will wait for input then assign it to the variable,
 * in this case it will wait for an int.
 */
System.out.println(i); // will print the variable
