Reading System.in for Intellij using Console
提问by daidaidai
I need to open up the console and type in inputs for my an assignment using Intellij.
Eclipse has a way of doing this using the Scannerclass and reading System.inbut running the same code in IntelliJ does not work as I can't type anything into the console.
我需要打开控制台并使用 Intellij 为我的作业输入输入。Eclipse 有一种使用Scanner类和读取的方法来执行此操作，System.in但在 IntelliJ 中运行相同的代码不起作用，因为我无法在控制台中输入任何内容。
Is there any way to do this?
My code is as follows:
有没有办法做到这一点？
我的代码如下：
public class BasicAssertions {
@Test
public void testAssertions(){
System.out.println("Enter: ");
Scanner reader = new Scanner(System.in);
int first = reader.nextInt();
int second = reader.nextInt();
String s = reader.next();
String s2 = reader.next();
assertTrue(first<=second);
assertFalse(first+second >100);
assertNotEquals(s,s2);
assertNotNull(s2);
}
}

Resolved. A public static void main()method is required for the correct console to appear, otherwise running using the default JUnit Test configurationwill only result in a console that doesn't receive inputs.
解决。public static void main()需要一个方法才能显示正确的控制台，否则使用默认的JUnit 测试配置运行只会导致控制台不接收输入。

Just click on the console window and type, it works for me on IntelliJ 13 CE. See the image below, I clicked in the console and wrote the text (it appears in green then, I typed enter and it shows up):
只需单击控制台窗口并键入，它在 IntelliJ 13 CE 上对我有用。参见下图，我在控制台中单击并编写了文本（然后它显示为绿色，我输入 enter 并显示）：
