Display java application errors in terminal/console - java

As you know when we building applications we get Errors/Exceptions such as NullPointerException etc. on IDE Console (I'm using IntelliJ IDEA).
I want to display those errors simultaneously in my Mac Terminal for larger view so I don't have to horizontally scroll IDE Console every time when I get big errors.
I don't want to run my applications from Terminal with commands (java class...)
I want to run from my IDE and all texts which is going down(errors,exceptions infos.) will reflect to Terminal.
So is there a any log file that i can look into? How can I achieve this?

In the Logs tab of an IntelliJ IDEA run configuration, there is an option "Save console output to a file". You can use that to save the output of your application to a file and to view it in the terminal.

Error while running a program on java on visual studio code

This is the porgram which I am running on visual studio code
When I run the program I am getting this error box
After getting the error box, it is showing this page.
What shall be done in this for the program to run on VS Code?
There should be multiple java files inside the folder you are currently opening in vscode and you are running one of them. There is a bug in another java script that causes a compilation error when you run the current file.
It doesn't matter, you just need to click on Proceed in the popup, which will continue to run the current code. As long as your current code has no errors, the program will run successfully and output the result.
Another way is to install Code Runner and then use the Run Code option it brings to run the code. This way it will only compile and run the current file, and will not bring compile errors.
But be aware that Code Runner may have errors when your file structure is complex.

System.out.println where does it write to in Intellij Idea?

I can't find the terminal where the message is supposed to show. How is it called?
I'm guessing it should be in View->Tool Windows but nothing from there seems to work. It's a Maven project and all I can see is GlassFish log.
System.out and System.err output is written to either the Run or the Debug tool window depending on whether you launch the run/debug configuration as Run or Debug. See https://www.jetbrains.com/idea/help/running-and-debugging.html and https://www.jetbrains.com/idea/help/run-tool-window.html for more information (Same information is in the Help guide of the IntelliJ IDEA Ultimate version).
In Java EE applications with Tomcat container, if you want to see the result of prints like System.out.println(), first go to Run > Edit Configurations and select your tomcat server in the left menu, then open Logs tab and check 'Show console when a message is printed to standard output stream'
Click on the below image to figure out.
For running mode:
View -> Tool Windows -> Run
For debugging mode:
View -> Tool Windows -> Debug
You must be on one of the above two states in order to accomplish this action.

How to view console output for an eclipse plugin installed in the workbench in which it was created?

Hi iam new to eclipse plugin development , iam trying to create a simple plugin having a menu . I have installed it in the same eclipse workbench in which it was developed . However if i click on it i dont see the output in the console view . Howveevr if i run the project as a seperate eclipse app in a seperate workbench it works but shows the output in original workbench in which it was developed .
Can anybody help me out how to view the plugin output in the same workbench , irrespective of whether it is a new workbench or the same workbench in which it was developed
Any help is highly appreciated .
Thanks
I think what you want is to start the workbench as eclipsec. This eclipse launcher opens a terminal window next to the workbench in which console output (i.e. things written to System.err / System.out) appears.
There is no simple way to put output in the console in both cases.
When you run in a separate workbench the console is just showing the output from System.out and System.err. Your plugin is running as part of a separate Eclipse in a new JVM, the Eclipse console is showing everything that is output by that JVM.
When you are running in the same workbench you would have to use the console APIs in the org.eclipse.ui.console package and extension points such as org.eclipse.ui.console.consoleFactories to create a console and write to it.

run java program in eclipse with data input

I seem to be able to run Java programs and get output in Eclipse when I use StdOut.println(...). I have a program that reads from StdIn and should print to StdOut. I know the program works because I have submitted it to a class autograder and got a perfect score on it, but I must be doing it wrong in Eclipse. Please explain how to set this up. I thought I understood how to use the "Run Configuration", but obviously I don't.
Follow these steps.
Right click on the project that you want to run. (In Eclipse)
From the appeared menu, Select Run As
Then finally select Java Application
And make sure, Your console is visible in your Eclipse IDE,
To Enable it,
Goto Windows tab in Eclipse IDE
Then Select Show View
Finally select Console

Pop up command line in Eclipse or NetBeans

currently for my Java code writing I am using Windows and JCreator 2.5 LE. It is ancient and has basically no frills, but it has 1 thing that I like about it. When I run/debug a program, a Windows command line windows pops up and my program runs. I really like Eclipse and NetBeans, NetBeans I like a little bit moreso, but when I run my code it comes up in that stupid tiny little console embedded window, now this might not annoy anyone out there, but I like how I get the full command line window to pop up and run my code in good old windows cmd.exe goodness. Maybe I'm just a scrub but that's what I'm used to, all C/C++ work I've done in CodeBlocks and/or MS Visual Studio IDE, when I hit run I have a command line window pop up just like in JCreator, so that's what I'm used to.
So please, is there any way to get either NetBeans or Eclipse to do what I am asking?
Add just a simple script / bat file to execute your main Java class.
In "start_app.bat"
cd path_to_build_dir
java package_name.Main
augument with pause and other stuff as you prefer.
Or you can modify your build as described here http://wiki.netbeans.org/CLIProjectInConsoleWindow#How_to_run_a_NetBeans_project_in_an_operating_system_console_window
