Eclipse Console not showing output
提问by user3497430
I have written a simple class having an SOP statement for "Hello World". But the Eclipse console is not showing output. I then wrote the same program in a previously created project and it worked fine. I am opening the Console as given below:
我编写了一个简单的类，其中包含“Hello World”的 SOP 语句。但是 Eclipse 控制台没有显示输出。然后我在以前创建的项目中编写了相同的程序，并且运行良好。我正在打开控制台，如下所示：
Window->Show View->Console.
窗口->显示视图->控制台。
But it is not working. I am using j2ee project in the same workspace. Any idea? Please help. I am stuck because of this problem.
但它不起作用。我在同一个工作区中使用 j2ee 项目。任何的想法？请帮忙。由于这个问题，我被卡住了。

Go to "Window > Reset Perspective", that will reset the window settings to default. Next, you might need to stop any running Java processes. I suggest you then click "Remove all Terminated Launches" and if the red "Terminate All" is still available click that as well
转到“窗口>重置透视”，这会将窗口设置重置为默认值。接下来，您可能需要停止任何正在运行的 Java 进程。我建议您然后单击“删除所有终止的启动”，如果红色的“终止所有”仍然可用，请单击它

Make sure that your System.out.println("Hello World") is in mainmethod with proper signature.
确保您的 System.out.println("Hello World") 在具有正确签名的main方法中。
Ex:
前任：
public static void main(String[] args){
System.out.println("Hello World");
}

None of the above. What helped in my case:
以上都不是。什么对我有帮助：
Run> Run configurations> Common> uncheckLaunch in background(last tab all the way at the bottom).
运行>运行配置>通用>取消选中在后台启动（最后一个选项卡一直在底部）。
Then it showed the error why the thing wouldnt start.
然后它显示了为什么事情不会启动的错误。
In my case: a project dependency to a project which I had closed.
就我而言：项目依赖于我已关闭的项目。
See (rightclick) Project> Build path> Configure build path.
请参阅（右键单击）项目>构建路径>配置构建路径。

Double-check you actually saved your file. Many of us forget to save the file and simply hit run.
仔细检查您是否确实保存了文件。我们中的许多人忘记保存文件并直接点击运行。
