java – System. Console () returns null from eclipse, but the command prompt is good
•
Java
When I use eclipse Helios system Console, it always returns null
However, when I use it directly from the command line (that is, manually compiling and executing java source code from the command prompt), I get a console object
You know, why did this happen? I checked the this link According to it, when I run my java code from eclipse, the background job scheduler must start my JVM What's the meaning of this?
How different is my JVM when I start it from the command line?
I also checked this link Here McDowell says CMD Exe is a console device So I'm confused again. Is that really a console device?
Solution
Because it is a bug in eclipse #122429
