Eclipse从控制台读取StdIn（System.in），但不会给出任何输出 [英] Eclipse reading StdIn(System.in) from console, but will not give any output

问题描述

我的问题是Eclipse的控制台正在控制台中输入，但它永远不会停止输入，也不会给我任何输出。我创建了一个名为histogram（）的方法，它采用整数M和整数数组a作为输入。我读取输入和生成输出的代码类似于

My problem is that Eclipse's console is taking input in the console, but it never stops taking input and will not give me any output. I created a method called histogram() that takes an integer M and an array a of integers as input. My code to read input and produce output looks like

    int M = StdIn.readInt();
    int[] a = StdIn.readAllInts();
    int[] mossah = histogram(M, a);
    for (int z = 0; z < M; z++) {
    StdOut.printf("%d", mossah[z]);
    } 

我不允许使用其他库，所以请不要建议使用其他库。我在想，也许有某种键盘快捷键可以让控制台停止输入，但我不确定。我也尝试使用 StdIn.readInts（），这给了我一个错误，它被折旧了，对于数组a的输入，但它也没有用。如果我在代码中为数组a赋值，我得到了我想要的输出，所以我的方法没有任何问题，只是我为你们提供的代码片段。非常感谢任何帮助。

I am not allowed to use other libraries, so please do not suggest one. I was thinking that maybe there's some kind of keyboard shortcut that will make the console stop taking input but I'm not sure. I also tried using StdIn.readInts(), which gave me an error that it was depreciated, for array a's input, but it also did not work. If I assign values to array a in the code, I get my desired output, so there is nothing wrong with my method, just that code snippet I put for you guys. Any help is greatly appreciated.

推荐答案

假设您在Windows上按Ctrl-Z发送EOF字符

Assuming you are on windows hit Ctrl-Z to send the EOF character
