Eclipse Console not showing output

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:

Window->Show View->Console.

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.

Sometimes it is possible that number of character console can accomodate is beyond capacity, so increase the buffer size of console. windows>prefences>console -increase buffer size

I've lost the console only in the Java default perspective and I wasn't able to show it again by using window > show view > console.

What I did is the following :

  1. window > Perspective > reset perspective
  2. window > show view > console

and It appears now!!

If eclipse is not showing path,

Please click on RUN-> Run configuration->click on environment tab->click on New-> add a path variable as mingw_path(if compiler is mingw in case of c++ ) and set value as C:\MinGw\bin (please check ur mingw bin path then only set).

Double-check you actually saved your file. Many of us forget to save the file and simply hit run.

None of the above. What helped in my case:

Run > Run configurations > Common > uncheck Launch in background (last tab all the way at the bottom).

Then it showed the error why the thing wouldnt start.

In my case: a project dependency to a project which I had closed.

See (rightclick) Project > Build path > Configure build path.

[working] I encountered the same problem, I tried with all the solutions provided above but it didn't work then I came to a solution which worked. Follow the following process to overcome the problem.

Right click on workspace provided by Eclipse --> Select "Run As" --> Java Application.

enter image description here

This will work definitely.

  1. Just right click on console window and click Terminate /Disconnect all.
  2. Run the class again
  3. Done !!!

Make sure that your System.out.println("Hello World") is in main method with proper signature.

Ex:

public static void main(String[] args){
System.out.println("Hello World");
}

I had the same problem just figured out the solution. Just check your main method it would be 

public void main(String[] args){

just change it to this:

public static void main(String[] args){

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

Remove all Terminated Launches
