Visual Studio Code – How to stop vscode from printing extra lines when running Java

I just installed vscode along with the coding pack for Java from the vscode website, and whenever I run a Java program, it prints two extra lines in the terminal, one with a "^C" and another one that’s blank.

I’ve tried messing around with uninstalling the default java extensions and changing some of the settings but I can’t get it to go away. Any help?

    Try these solutions:

    1. Check for Auto Save and Auto Run Settings:
    • Make sure that the auto save or auto run settings are not interfering
      with the execution of your code. You can check these settings in VS
      Code:
    • Open the command palette (Ctrl+Shift+P or Cmd+Shift+P on Mac).
    • Type and select Preferences: Open Settings (JSON).
    • Look for settings related to "files.autoSave" and
      "java.debug.settings.hotCodeReplace" and see if changing them affects
      the behavior.
    1. Disable Auto Execution of Code:
    • If you have any extensions or settings that might be causing the code
      to auto execute, try disabling them temporarily to see if the issue
      goes away:
    • Go to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on Mac).
    • Disable any extensions that might be automatically running your code.
    1. Check the Run Configuration:

    • Review the run configuration to ensure that it’s not causing the
      extra output:

    • In VS Code, go to the Run and Debug view (Ctrl+Shift+D or Cmd+Shift+D
      on Mac)

    • Check your launch configurations and make sure there are no
      additional tasks or settings that might be affecting the execution.

    1. Terminal Settings in VS Code:
    • The integrated terminal in VS Code might have settings or
      behaviors that cause extra output. Check your terminal settings:
    • Open the command palette (Ctrl+Shift+P or Cmd+Shift+P on Mac).
    • Type and select Preferences: Open Settings (JSON).
    • Look for terminal-related settings and ensure there are no unusual
      configurations.
    1. Check Java Extension Settings:
    • Review the settings for the Java extensions you have installed in VS
      Code: Go to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on Mac).
    • Find the Java extensions (e.g., Java Extension Pack, Debugger for
      Java, Java Test Runner).
    • Check their settings for any configuration that might affect the
      output or termination of the Java program.
    1. Reinstall Extensions:
    • If you suspect the issue might be with the Java extensions, try
      uninstalling and reinstalling them:
    • Go to the Extensions view.
    • Uninstall the Java-related extensions.
    • Restart VS Code.
    • Reinstall the Java extensions from the marketplace.

    you can try to download the plugin Code Runner. Once the download is complete, select the settings.json file. Set the following in the file:

     "code-runner.runInTerminal": false,
    "code-runner.showExecutionMessage": false,
    "code-runner.fileDirectoryAsCwd": false,
    "code-runner.executorMap": {
        "ruby": "C:\Ruby23-x64\bin\ruby.exe",
        "go": "go run",
        "cpp": "clear && cd $dir && g++ $filerName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",
        "perl": "perl",
        "python": "python",
        "javascript": "node",
        "java": "cd $dir && javac -encoding utf-8 $fileName && java -Dfile.encoding=UTF-8 $fileNameWithoutExt"
    },

    Then save the settings and restart the vscode attempt.
    Besides, you can try changing the settings for .vscode/launch.json. Change the console settings to "console": "internalConsole". This will allow it to output results in the debug console.
