How to start the java console when launching an application from Eclipse?
提问by Jenny Smith
When I start a java application, the Java Console is started. But when I start a java application from Eclipse, the Java Console does not start on its own. How can I make it start also when I run an application from Eclipse?
当我启动 Java 应用程序时，会启动 Java 控制台。但是当我从 Eclipse 启动 Java 应用程序时，Java 控制台不会自行启动。当我从 Eclipse 运行应用程序时，如何让它也启动？

What for do you need java console? There is window console in Eclipse IDE where all System.out.println are redirected.

If you are wanting the program to start in it's own window. Try running it as an external tool. The program would be cmd.exe and the argument would be your java command line, e.g. "java -cp c:\myclasspath myProg" and so forth.
如果您希望程序在它自己的窗口中启动。尝试将其作为外部工具运行。该程序将是 cmd.exe，参数将是您的 java 命令行，例如“java -cp c:\myclasspath myProg”等等。

First check that no other console is pinned, icon looks like window with a needle in it. This means that no other console except the one that is pinned will show the output. If everything else fails try to reset the java perspective in Eclipse.
首先检查是否没有固定其他控制台，图标看起来像带有针的窗口。这意味着除了被固定的控制台之外，没有其他控制台会显示输出。如果其他一切都失败了，请尝试在 Eclipse 中重置 Java 透视图。
